This compact device saves up to 90% of mobile phase by redirection of the pure solvent to the solvent reservoir during the isocratic HPLC. The device is powered by 5 V DC from computer USB port or power adapter. Working parameters (Threshold and Delay) are set using user friendly software.<blockquote>Price: 635<bdi>&nbsp;€ ex VAT</bdi></blockquote>The UFO Solvent Recycler continuously monitors the output signal of the chromatography detector and displays its current value in the application on computer. A high-resolution analog-to-digital converter provides data for further evaluation in the built-in processor.If the input signal level exceeds a preset value (Threshold), the UFO recycler will redirect the flow to the waste. When the signal drops, the solvent recycler waits for the transport delay and then switches the mobile phase back to the reservoir. An autosampler injection marker connected to the UFO recycler START input can be used to zero the input signal at the time of injection.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UFO_schema_6a4cdc0ed4/UFO_schema.png" alt="Watrex: Principle and process of mobile phase recycling during isocratic HPLC using the UFO system" width="1348" height="1378"><h3>FEATURES</h3><ul><li>Very compact design</li><li>Simple operation</li></ul><h3>TECHNICAL SPECIFICATION</h3><ul><li>Detector compatibility: compatible with any HPLC detector</li><li>Connection: 1/16″ O.D. tubing, 1/4″-28 flat bottom fittings</li><li>Maximum pressure: 30 p.s.i./0,2 MPa</li><li>Wetted material: PEEK, PTFE</li><li>Input range: +/- 1 V or +/- 100 mV, user selectable</li><li>Computer connection: USB-A</li><li>TTL/contact closure input: configurable (ZERO, start, valve position)</li><li>Power: 5V DC/&lt;100 mA (power supply or computer USB port)</li><li>User interface: PC Windows based software</li></ul><h3>Ordering information:</h3><h5>PN/Component:</h5><ul><li>UFO000-001 UFO™ Solvent Recycler , PEEK version</li><li>UFO000-002 UFO™ Solvent Recycler , PTFE version</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_UFO_1_01268632dd/Watrex_UFO_1.jpg" alt="Watrex: Introducing Watrex UFO Solvent Recycler." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Watrex_UFO_1_01268632dd/thumbnail_Watrex_UFO_1.jpg 177w," sizes="100vw" width="1310" height="1152"><blockquote><h4>Selected document from Watrex in <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=93">LabRulesLCMS library</a>:</h4><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/Watrex_catalog_2024_ba97395f92.pdf">Watrex product catalog 2024</a></h5><ul><li>HPLC, GPC/SEC, Sample Preparation, LC columns, Consumables</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1341">WATREX SYRINGE FILTERS</a></h5><ul><li>Consumables</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products?category=48&amp;distributorItems=59&amp;manufacturerItems=93">Watrex HPLC COLUMNS</a></h5><ul><li>Consumables, LC columns</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/Watrex_Clean_Water_for_Quality_Results_Rely_on_Our_Water_Systems_dc404f75df.pdf">Clean Water for Quality Results: Rely on Our Water Systems</a></h5><ul><li>Laboratory instruments</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/300">Watrex - LSS-205 Liquid Sensing System</a></h5><ul><li>Laboratory instruments, HPLC</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/4671">8 points on how to care for columns</a></h5><ul><li>Consumables, LC columns</li></ul><h5><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products?category=179&amp;distributorItems=59&amp;manufacturerItems=93">Watrex WATER PURIFICATION SYSTEMS</a></h5><ul><li>Laboratory instruments &nbsp;</li></ul></blockquote>

Watrex SYRINGE FILTERS

Syringe filters (filters for syringes) are a universal tool that ensures sample purity and prevents contamination of analytical instruments.

Syringe filters (filters for syringes) are a universal tool that ensures sample purity and prevents contamination of analytical instruments. They are single-use filters used for precise filtration of liquids before their application or analysis.Pore Size: Filters come in various pore sizes, ranging from 0.2 μm to 5 μm, depending on the required level of filtration. Smaller pores (e.g., 0.22 μm) are often used for sterilizing solutions, as they capture bacteria and other microorganisms.We offer syringe filters in the following sizes: 4 mm, 13 mm, 25 mm, and 30 mm, all available with pore sizes of 0.22 μm and 0.45 μm.Filter Material: Syringe filters are made from different materials that are compatible with various sample types. It is important to select the correct filter material based on the chemical composition of the sample. We offer syringe filters made from the following materials:<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_Watrex_SYRINGE_FILTRY_b6ffda00e2.jpg" alt="Watrex: Watrex SYRINGE FILTERS" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Watrex_Watrex_SYRINGE_FILTRY_b6ffda00e2.jpg 245w," sizes="100vw" width="1808" height="1017"><h4>Nylon</h4><ul><li>Suitable for aqueous solutions and most organic solvents.</li><li>It has strong mechanical stability and excellent chemical compatibility with esters, bases, phenols, and alcohols.</li></ul><h4>PTFE (Polytetrafluoroethylene)</h4><ul><li>Chemically resistant to most organic solvents.</li><li>It has very broad chemical and thermal compatibility.</li><li>PTFE filters are recommended for strong acids and bases and are excellent for filtration and degassing chromatography.</li></ul><h4>PVDF (Polyvinylidene fluoride)</h4><ul><li>Suitable for biological samples.</li><li>It has good chemical resistance and low UV absorption.</li><li>Commonly used for filtering all water-based samples and most solvents.</li></ul><h4>PES (Polyester)</h4><ul><li>Ideal for water-based samples, especially biological ones, with a fast and high flow rate.</li></ul><h4>MCE (Mixed Cellulose Esters)</h4><ul><li>Ideal for aqueous samples, tissue cultures, and sensitive biological samples.</li><li>It has lower chemical resistance, excellent water flow, and a better cutoff effect.</li></ul><h4>PP (Polypropylene)</h4><ul><li>Ideal for filtering all water-based samples and most solvents.</li><li>Used for general filtration of biological samples, solvents, deionized water, and reducing biological load.</li><li>It has good thermal compatibility.</li></ul><h5>Examples of Use:</h5><ol><li>Sterilization of solutions: Filtration can remove bacteria and other microorganisms from solutions.</li><li>Sample purification: Samples are filtered before analysis to remove solid particles that could contaminate analytical instruments or affect analysis results.</li><li>Preparation for chromatography: Filtration before entering devices like HPLC (High-Performance Liquid Chromatography) to ensure sample purity.</li></ol>

ECOM Separchrom PC01-HPLC Industrial Preparative Columns with Axial Compression

Separchrom PC01 ECOM industrial preparative columns correspond to the highest requirements of preparative liquid chromatography. They are designed to be used in a mode of axial compression with a moving input piston. 

<div style="display:block;" aria-labelledby="tab_item-0">HPLC Columns for prep chromatography. High performance columns with axial compression.Separchrom PC01 ECOM columns correspond to the highest requirements of preparative liquid chromatography. They are designed to be used in a mode of axial compression with a moving input piston. In the original design, they are equipped with identical pistons on input and output (biaxial compression as an option). In the ECOM Separchrom PC FE modification, they have a fixed end plate on the output instead of the piston. Pistons and plates are equipped with frits. A liquid distributing system is installed under each frit. The design guarantees perfect piston flow, high efficiency even for high injection volume, and simple accessibility of frits for cleaning. Columns can be packed by dynamic slurry method or by sedimentation or with sorbent in a dry state.SEPARCHROM PC 01 ECOM columns are made of stainless steel AISI 316L (tube inner surface is polished to reach Ra &lt; 0.3 µm) with stainless steel pistons and UHMWPE (PTFE on the request) sealing rings. The stroke of the main piston is proportional to the used hydraulic cylinder or flange bolt length. Pistons are sectional; the frit (sintered mesh disc 3 µm pore size, 5 mm thickness) with the frit ring can be removed. The output plate in the FE version is made of UHMWPE, frit is fixed with a simple frit ring. Column flanges are not welded, but screwed onto the column tube. No temperature increase during manufacturing means no change in steel properties. The column stand made of stainless steel profiles is included for columns over 100 mm I.D.Hydraulic cylinders fitted on the upper flange are offered with manual oil pumps as well as with fully automated electric motor-driven devices for column packing/unpacking procedures.<h3>Accessories</h3>Columns are offered with a broad scale of accessories such as filling adapters, slurry mixing vessels, slurry transporting pumps, etc.<h3>COLUMN CONFIGURATION EXAMPLES</h3>Columns are custom-made, do not hesitate to ask for any other sizes within the possible ranges<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_1_1795482301.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 1" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_1_1795482301.jpg 236w," sizes="100vw" width="1440" height="952"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_2_6d3198af67.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 2" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_2_6d3198af67.jpg 239w," sizes="100vw" width="1442" height="942"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_3_9fd77a1054.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 3" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_3_9fd77a1054.jpg 245w," sizes="100vw" width="1435" height="315"></div>
