<p><strong>The international standard ISO/IEC 17025 [1] clause 7.7.2 with regards to ensuring the validity of results, requires a laboratory to participate in proficiency testing (PT) and/or to participate in interlaboratory comparisons (ILCs) other than PT. However, no guidance as to what these other ILCs might be, or indeed how they might compare in relation to PT, is provided. This leaflet aims to outline other ILCs available, pointing out some of the limitations as compared to PT.&nbsp;</strong></p><p>There are three major types of ILCs in which a group of laboratories analyses identical portions from a homogeneous, stable test sample, with each type being characterized by its intended purpose [2,3]:</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg 245w," sizes="100vw" width="1507" height="607"></p><p>A key point is that PT is an ILC that is designed to specifically evaluate the performance of participants, providing them with an infrastructure to monitor and assess the validity of their results. This is not the key purpose of the two other ILCs, and thus depending on their intended purpose they have a number of limitations that laboratories need to be aware of when using them rather than PT. Only proficiency testing should have been conducted in full compliance to the competency standard ISO/IEC 17043 [4].&nbsp;</p><h4><strong>Evaluation of measurement procedure performance&nbsp;</strong></h4><p>These ILCs, are designed to assess how a particular measurement procedure performs and whether it is fit for its intended purpose. These ILCs are often referred to as a ‘method performance study’ or a ‘collaborative study’ [2]. Some limitations of using such ILCs for monitoring laboratory performance as an alternative to PT are:&nbsp;</p><ul><li>All participants use the same measurement procedure i.e. the measurement procedure that is being validated. Unless the measurement procedure is being routinely used by the participating laboratory such an ILC will not assess the routine performance of the laboratory using their own routine measurement procedure. Nor does it enable them to compare their performance with other laboratories using alternative measurement procedures.&nbsp;</li><li>The measurement procedure is likely to be new, so participants may not have established stable procedures and quality control, so performance may not reflect routine use.&nbsp;</li><li>The report from such an ILC would not provide information on the performance of the participant, if the statistical model used makes the assumption that all laboratories perform with equal variability.</li><li>The design of the study may require the participants to assess multiple samples and/or to undertake multiple replicate analysis on the test materials. This may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li><li>The conclusion of the ILC might be that the measurement procedure being assessed is not valid.&nbsp;</li></ul><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg 157w," sizes="100vw" width="570" height="566"></p><h4><strong>Characterisation of candidate reference materials&nbsp;</strong></h4><p>These are ILCs that assign a property value to a candidate reference material, usually with a stated measurement uncertainty. These are often referred to as a ‘material certification study’ [2]. Limitations of using such ILCs as an alternative to PT are:&nbsp;</p><ul><li>The analysis of the candidate reference material is likely to require additional care in exercising the routine measurement procedure, such as substantially more replication, and/or may require quite different reporting formats (e.g. all valid replicates instead of a mean result). Thus, such an ILC will not necessarily provide an evaluation of the performance of the laboratory based on the routine use of their measurement procedures.&nbsp;</li><li>The report from such an ILC may include the results from the participating laboratories but would not provide information on the performance of each laboratory.&nbsp;</li><li>Participating laboratories may be required to assess multiple samples and/or to undertake multiple replicate analysis on the candidate reference materials. Thus this may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li></ul><h4><strong>Other ILCs&nbsp;</strong></h4><p>Some other ILCs, whilst not being conducted in full compliance of the requirements of ISO/IEC 17043, may be designed to evaluate participant performance. These would include small ILCs as defined by EA‑2/21 [5] or split sample ILCs i.e. where a portion of a single sample is sent to two or three laboratories. Whilst these ILCs are specifically designed to evaluate participant performance, they may not provide a comprehensive comparison that a PT might provide. In such cases the laboratory needs to evaluate carefully the competence of the organization managing the ILC and the suitability of the service externally provided (ISO/IEC 17025 clause 6.6).</p>

Samplify Is a device which allows unattended sampling of a reaction mixture or bioprocess or continue in line flow by taking small amount of liquid from the monitoring mixture and collecting it in a vial or a 96 wells plate

<p><strong>Samplify™ Is a device which allows unattended sampling of a reaction mixture or bioprocess or continue in line flow by taking small amount of liquid from the monitoring mixture and collecting it in a vial or a 96 wells plate. It also allows to dilute the sample with assigned dilution ratio and can provide reaction quenching to preserve the sample state at time of sampling. It has two main components: an autosampler and a probe. The Samplify™ &nbsp;controlled and setup by a PC software.</strong></p><h3><strong>Description</strong></h3><p>It is a common task in the lab to <strong>periodically sample a reactor</strong> or a fermenter to <strong>obtain information about reaction kinetic, completion and have a tangible representation of intermediate states of a dynamic process</strong>. This usually done manually with pipettes or syringes, using stopwatch to measure time and requires to be in the lab during the entire process.</p><p><strong>With Samplify it can be done in automated mode.</strong> When an automated sampling process is used it increases accuracy, safety, and productivity. It reduces potential samples cross contamination, and exposure of the reaction mixture to oxygen or moisture, when anaerobic or moisture free conditions are required.</p><ul><li>Based on a proprietary alpha/beta mechanical configuration, <strong>Alltesta Miniature Autosampler</strong> and patent pending sample probe offers affordable and reliable <strong>automation</strong> <strong>for many analytical and liquid-handling applications</strong>.&nbsp;</li><li>Small <strong>controllable volume of sample</strong> can be programmed and precisely removed from the <strong>enclosed or open system</strong>. The sample will then be transferred to a vial with inert solvent with measured volume to create a <strong>controllable dilution factor</strong>.</li><li><strong>A quench solution can be automatically preloaded</strong> in each vial to provide termination of reaction or biological process, and preserve sample content in the time of probing.</li><li>In order to effectively mix samples with diluents or quenching reagents a <strong>shaking capability</strong> of the autosampler tray can be initiated after each sample cycle.</li><li><strong>PC based software</strong> allows quick, but flexible, setup of the sampling experiment. Several <strong>preloaded methods</strong> can be quickly adapted to a particular needs of the user.</li><li>For temperature sensitive samples the entire autosampler can be placed in the <strong>temperature controlled</strong> environment.</li><li>The device <strong>small size</strong> allow to place it close to the reactor and use <strong>short connection lines</strong> to minimize dispersion.

<p><strong>Our 45-position nitrogen evaporator (Catalog # 11645) offers the largest number of sample positions in our N-EVAP line. The sample holder has dual circular rings. The outer ring has 30 positions and can accommodate samples with an outside diameter of 10-19 mm The inner ring has 15 positions and can accommodate samples with an outside diameter of 16-30 mm and a minimum height of 70 mm.</strong></p><p>This time-tested, durable system provides the least expensive price per position of all our N-EVAPs. The evaporative system, along with the standard flow control and pressure reducing regulator, enables the operator to achieve the desired level of concentration with efficient nitrogen usage. Our unique dual band spring hoist assembly ensures easy and effective operator use. Additionally, the 45 position N-EVAP includes a side control box. Timed, digitally controlled water bath temperatures provide even evaporation rates. The pressure regulator and timer combine to allow timed automatic gas flow cut off which slows evaporation to a minimum once the timed cycle has been completed. The heat can also be shut off with the gas after a timed cycle.</p><ul><li><strong>Gentle: </strong>N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to gently concentrate delicate samples</li><li><strong>Flexible: </strong>An adjustable sample holder design fits a wide variety of sample tubes and vials at once</li><li><strong>Precise: </strong>Digital controls allow exact temperature regulation</li><li><strong>Individualized Control: </strong>Optimize evaporation of diverse samples with individual gas flow control at each vial</li></ul><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Organomation_45_Position_N_EVAP_Nitrogen_Evaporator_5_20078e3969.jpg" alt="Organomation: 45 Position N-EVAP Nitrogen Evaporator." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Organomation_45_Position_N_EVAP_Nitrogen_Evaporator_5_20078e3969.jpg 156w," sizes="100vw" width="1400" height="1400"></p><h3><strong>STANDARD FEATURES</strong></h3><ul><li>Nitrogen filter</li><li>Adjustable flow meter, 0-30 LPM</li><li>Built-in pressure reducing regulator</li><li>Side control box</li><li>Digital temperature controller</li><li>Electronic timer</li><li>Safety control cover plate</li><li>High pressure phthalate free tubing&nbsp;</li><li>High temperature limit switch for safety</li><li>Dual band spring hoist assembly&nbsp;</li><li>Precision needle valve tube assembly</li><li>Needles, 4 inch x 19 gauge with chrome plated brass hub and stainless steel shaft</li></ul><h3><strong>OPTIONS&nbsp;</strong></h3><ul><li>220v wiring harness (Option Code# -2), Cat# 11645-2</li><li>Z-Purge/positive pressure purge case (Option Code# -Z), Cat# 11645-Z</li><li>Acid resistant coating on instrument and needles (Option Code# -RT), Cat# 11645-RT</li></ul><h3><strong>SPECS</strong></h3><h4><strong>45 Position N-EVAP (Water Bath)</strong></h4><ul><li><strong>Bath Type</strong>: Water</li><li><strong>Instrumental Catalog Number</strong>: 11645</li><li><strong>Number of Sample Positions</strong>: 45</li><li><strong>Overall Dimension (w × d × h)</strong>: 24 × 19 × 34 in / 61 × 48 × 86 cm</li><li><strong>Sample Holder Layout</strong>: Circular</li><li><strong>Gas Manifold Layout</strong>: Dual Rings</li><li><strong>Outer Circle Sample Holder Test Tube Range</strong>: 10–19 mm OD</li><li><strong>Inner Circle Sample Holder Test Tube Range</strong>: 16–30 mm OD; &gt;70 mm height</li><li><strong>Gas Flow Meter</strong>: 0–30 L/min</li><li><strong>Stainless Steel Needles (Length × Gauge)</strong>: 4.0 in × 19 ga / 102 mm × 19 ga</li><li><strong>Sample Tray Lift Mechanism</strong>: Dual Band Spring Hoist Assembly</li><li><strong>Rotating, Leak Tight Gas Fitting</strong>: Standard</li><li><strong>Built-in Nitrogen Gauge Input</strong>: 30–110 psig</li><li><strong>Acid Resistant Coating</strong>: Optional</li></ul><h5><strong>Heating Device Specs</strong></h5><ul><li><strong>Model Number</strong>: 13165</li><li><strong>Heating Medium</strong>: Water</li><li><strong>Inside Dimensions (Diameter × Depth)</strong>: 16.0 × 4.5 in / 40.6 × 11.4 cm</li><li><strong>Outside Dimensions (w × d × h)</strong>: 24 × 19 × 6 in / 61 × 48 × 15 cm</li><li><strong>Total Wattage</strong>: 1300 W</li><li><strong>Bath Temperature Range</strong>: 30–90 °C</li><li><strong>Temperature Controller Type</strong>: Digital Electronic with LED Display</li><li><strong>Controller Accuracy</strong>: ±2 °C</li><li><strong>Side Mount Control Box with Timer for Nitrogen &amp; Heat</strong>: Standard</li></ul><h4><strong>45 Position N-EVAP (No Bath)</strong></h4><ul><li><strong>Bath Type</strong>: None</li><li><strong>Instrumental Catalog Number</strong>: 11645-O</li><li><strong>Number of Sample Positions</strong>: 45</li><li><strong>Overall Dimension (w × d × h)</strong>: 24 × 19 × 32 in / 61 × 48 × 81 cm</li><li><strong>Sample Holder Layout</strong>: Circular</li><li><strong>Gas Manifold Layout</strong>: Dual Rings</li><li><strong>Outer Circle Sample Holder Test Tube Range</strong>: 10–19 mm OD</li><li><strong>Inner Circle Sample Holder Test Tube Range</strong>: 16–30 mm OD; 70 mm height</li><li><strong>Gas Flow Meter</strong>: 0–30 L/min</li><li><strong>Stainless Steel Needles (Length × Gauge)</strong>: 4.0 in × 19 ga / 102 mm × 19 ga</li><li><strong>Sample Tray Lift Mechanism</strong>: Dual Band Spring Hoist Assembly</li><li><strong>Rotating, Leak Tight Gas Fitting</strong>: Standard</li><li><strong>Built-in Nitrogen Gauge Input</strong>: 30–110 psig</li><li><strong>Acid Resistant Coating</strong>: Optional</li></ul><h3><strong>MODELS</strong></h3><h5><strong>Catalog Number &nbsp;/&nbsp;&nbsp;&nbsp;Bath Type</strong></h5><ul><li>11645: <strong>Water Bath</strong></li><li>11634-O: <strong>No Bath*</strong></li></ul><p><strong>*</strong>All “-O” models come with a base and stand assembly instead of a heated bath.
