Watrex product catalog 2024

Significance of the Topic

The versatility and reliability of modular liquid chromatography and laboratory automation instruments are pivotal for modern analytical chemistry. High-performance liquid chromatography (HPLC), ion chromatography (IC), gel permeation chromatography (GPC), and sample preparation systems support quality control, research, and environmental, pharmaceutical, and polymer analysis. Innovations in pump precision, detector sensitivity, temperature control, and workflow automation help laboratories improve throughput, reproducibility, and cost efficiency.

Objectives and Overview

This document reviews the Watrex Praha product catalog, detailing the company’s background and full suite of chromatographic modules. The objective is to provide an expert summary of instrumentation options, performance specifications, and practical applications, highlighting how each module integrates into complete HPLC, IC, GPC, or automated sample preparation systems.

Methodology and Instrumentation

Watrex Praha offers a modular portfolio:

• Pumps: Analytical and preparative dual-piston designs (P102, Streamline P1/P1s) with flow rates from microliters to tens of milliliters per minute, pressures up to 6000 psi, low pulsation, and active seal washing.
• Detectors: Variable-wavelength UV/VIS (UV1), photodiode array (PDA1), refractive index (RI1), and viscosimetric (VD1) detectors featuring high stability, low noise, and broad wavelength or refractive index ranges.
• Thermostats and Ovens: Column thermostats (CT1/CT1i) up to 100 °C and CTC-330 oven to 120 °C for improved separation consistency in temperature-sensitive analyses.
• Sample Handling: Fraction collectors (FC1), solvent recyclers (SPR-200, UFO), liquid sensing (LSS-205), post-column reaction systems (PCRS-300), on-line SPE (OLE 200), and cleanup systems (SCS 205) to automate workflows and reduce solvent waste.
• Automation: xTrovert XT robotic pipettor for high-throughput DNA/RNA extraction and sample processing with magnetic bead compatibility and UV-C sterilisation.
• Integrated Systems: Preconfigured HPLC, binary gradient, IC (chemically or electrolytically suppressed), and GPC systems with Clarity software control and optional autosampler and fraction collector modules.
• Columns: IonPlus columns for cations and anions, DeltaSil C18 for reversed phase, Polymer IEX for carbohydrate and organic acid analysis, and DeltaGel SEC columns for polymer characterization.

Main Results and Discussion

The Watrex portfolio demonstrates high precision pumps with flow reproducibility better than 0.2 % RSD, detectors with baseline noise in the 10–5 AU range, and thermostats with stability under 0.5 °C. Automation units reduce manual intervention, support open programming, and accommodate standard labware. Specialized cleanup and SPE modules streamline complex sample matrices, while solvent recyclers cut mobile phase consumption by up to 90 %.

Benefits and Practical Applications

Watrex systems enable robust method development, routine QA/QC testing, environmental monitoring, pharmaceutical impurity assays, carbohydrate profiling, polymer molecular weight determination, and nucleic acid sample preparation. Laboratories gain flexibility through modular upgrades, precise temperature control for sensitive analytes, and reduced reagent costs via solvent recycling.

Future Trends and Possible Applications

Advancements in digital connectivity, predictive maintenance, and AI-driven method optimization are emerging. Continued miniaturization, greener solvent systems, and integration of omics workflows will expand the role of automated chromatography platforms in high-throughput and clinical settings.

Conclusion

The Watrex Praha instrument catalog presents a comprehensive suite of chromatography and automation modules designed for performance, flexibility, and cost efficiency. Its modular architecture, broad detector options, temperature control solutions, and sample handling automation address diverse analytical challenges and support future innovations in laboratory workflows.
