Distillation, a popular technique for producing purified water in the past, has virtually completely supplanted by less energy-intensive and operationally dependable alternatives today. <strong>Reverse osmosis</strong> is the foundation of the majority of contemporary systems for <strong>producing purified water</strong>; in reality, this principle is supplemented with <strong>adsorption</strong>, <strong>ion exchange</strong>, <strong>filtration</strong>, <strong>ultrafiltration</strong>, and other physical-chemical techniques.</p>

Watrex SYRINGE FILTERS

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

<p><strong>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.</strong></p><p><strong>Pore Size: </strong>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.</p><p>We offer syringe filters in the following sizes: <strong>4 mm, 13 mm, 25 mm, and 30 mm</strong>, all available with pore sizes of <strong>0.22 μm and 0.45 μm</strong>.</p><p><strong>Filter Material:</strong> 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:</p><p><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"></p><h4><strong>Nylon</strong></h4><ul><li>Suitable for <strong>aqueous solutions</strong> and most <strong>organic solvents</strong>.</li><li>It has strong <strong>mechanical stability</strong> and excellent chemical compatibility with <strong>esters, bases, phenols, and alcohols.</strong></li></ul><h4><strong>PTFE (Polytetrafluoroethylene)</strong></h4><ul><li>Chemically resistant to most <strong>organic solvents</strong>.</li><li>It has very broad chemical and thermal compatibility.</li><li>PTFE filters are recommended for <strong>strong acids and bases</strong> and are excellent for filtration and degassing chromatography.</li></ul><h4><strong>PVDF (Polyvinylidene fluoride)</strong></h4><ul><li>Suitable for <strong>biological samples</strong>.</li><li>It has good <strong>chemical resistance</strong> and low UV absorption.</li><li>Commonly used for filtering all water-based samples and most solvents.</li></ul><h4><strong>PES (Polyester)</strong></h4><ul><li>Ideal for <strong>water-based samples</strong>, especially <strong>biological ones</strong>, with a fast and high flow rate.</li></ul><h4><strong>MCE (Mixed Cellulose Esters)</strong></h4><ul><li>Ideal for <strong>aqueous samples</strong>, <strong>tissue cultures</strong>, and <strong>sensitive biological samples</strong>.</li><li>It has lower chemical resistance, excellent water flow, and a better cutoff effect.</li></ul><h4><strong>PP (Polypropylene)</strong></h4><ul><li>Ideal for filtering all water-based samples and most solvents.</li><li>Used for general <strong>filtration of biological samples</strong>, <strong>solvents</strong>, <strong>deionized water</strong>, and reducing biological load.</li><li>It has good thermal compatibility.</li></ul><h5><strong>Examples of Use:</strong></h5><ol><li><strong>Sterilization of solutions: </strong>Filtration can remove bacteria and other microorganisms from solutions.</li><li><strong>Sample purification: </strong>Samples are filtered before analysis to remove solid particles that could contaminate analytical instruments or affect analysis results.</li><li><strong>Preparation for chromatography:</strong> Filtration before entering devices like HPLC (High-Performance Liquid Chromatography) to ensure sample purity.</li></ol><p><strong>You can also visit the full range of syringe filters on the </strong><a target="_blank" rel="noopener noreferrer" href="https://watrex.com/?s=syringe+filters&amp;post_type=product&amp;dgwt_wcas=1?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty"><strong>Watrex website</strong></a><strong>.</strong></p>

Watrex Streamline™ P1 HPLC Pump, PEEK

The Watrex Streamline™ P1 pump is a versatile and powerful dual-piston HPLC pump.

<p><strong>Streamline P1 pump, PEEK fully meets the demanding requirements for HPLC pumps and can be combined seamlessly with HPLC detectors and instruments from other manufacturers.</strong></p><blockquote><p class="cke-user_style-important"><strong>Price 4 935 € ex VAT</strong></p></blockquote><p>In the analytical version of the pump, the flow rate range from 0.001 ml/min to 10 ml/min is adjustable in 1 ul increments with a maximum working pressure of 42 MPa (6,000 psi). Flow rate adjustment accuracy is ±1% and flow rate variation is better than ±0.1%. The pump’s extremely smooth flow profile is ensured by an efficient pulse damper and optimized cam shape.</p><p>A unique feature is the active piston and seal rinse, which prevents crystallization of buffers. A touch screen display on the front panel allows intuitive control of the pump.</p><p>The display shows the flow rate, the current pressure and the pump is equipped with pressure limits. A <strong>PRIME function</strong> is also directly available for flushing at increased flow rates.</p><figure class="image"><img style="aspect-ratio:1024/768;" src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_Streamline_P1_Pump_PEEK_dbc4418900.jpg" alt="Watrex: Streamline™ P1 Pump, PEEK." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Watrex_Streamline_P1_Pump_PEEK_dbc4418900.jpg 208w," sizes="100vw" width="1024" height="768"></figure><h3><strong>TECHNICAL SPECIFICATION</strong></h3><ul><li><strong>Flow Rates:</strong> 0.001 to 10.000 mL/min</li><li><strong>Pressure:</strong> 0 to 6,000 psi (42 MPa)</li><li><strong>Flow precision:</strong> &gt; 0.2% RSD</li><li><strong>Flow accuracy:</strong> ± 1 % @ 1mL/min and 7 MPa,</li><li><strong>Pressure accuracy:</strong> ± 2% of full-scale, with 80:20 H2O/IPA @ 7 MPa</li><li><strong>Pulsation:</strong> ± 0.5 % @ 1mL/min and 7 MPa</li><li><strong>Remote inputs:</strong> USB</li></ul>
