Since its invention of the first lead-shielded syringe in 1947, Hamilton Company has set the standard for analytical fluid handling and measurement. This portfolio has since increased to include pipettes, polymeric HPLC columns, as well as process analytics sensors and equipment.
Jan 08, 2017 · How to choose right syringe filter is important for filtration. In this blog we are going to talk about the membrane materials used for manufacturing syringe filters. Please check the filter membrane chemical compatibility for the liquids you are going to filter.
BioFil™ Syringe Filter Why To use a syringe filter? Why choose Biofil™ Syringe Filter Futures 1. HPLC certification which guarantees the filters will not produce extraneous peaks in the UV range. 2. 100% integrity tested with higher burst strength ratings assuring they will perform consistently. 3.
Clear PTFE (Hydrophobic) Syringe Filters, 0.45 µm, 4 mm (200/Pack) have broad chemical compatibility and high pH resistance. These are versatile filters for use with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation. The pure polypropylene housings are.
2.1 Total recoverable metals - The entire sample is acidified at the tim e of collection with nitric acid. At the time of analysis the sample is heated with acid and substantially reduced in volume. The digestate is filtered and diluted to volume, and is then ready for analysis. 2.2 Dissolved metals - The sample is filtered through a 0.45-µm
33 mm syringe filter with a Hydrophilic PVDF membrane, for non-sterile filtration, has a 0.45 µm pore size used in preparation of protein-containing solutions prior to chromatography or other instrument analyses.
Parameter. SPARTAN HPLC Syringe Filter, 13 mm, regenerated cellulose, 0.45 µm, with mini-tip outlet (100 pcs) Application. For manufacturing of biopharmaceuticals for clinical phase I, II, and III studies. Depending on the scale of operations, they can also be used for full-scale manufacturing, as well as for preclinical studies. Bed dimensions.
For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives. Larger 0.45, 0.8, 1.2 and 5 µm membrane pore sizes can be used for prefiltration and/or clarification.
Removal of high particulate matter with a pre filter is critical before any drug, toxic, or dirty environmental sample is filtered to ensure the highest syringe filter membrane performance. Generally , 0.45 μm porosity filters are used to remove particulates from samples and mobile phase solutions.
MS ® mixed cellulose ester (MCE) membrane filters are composed of cellulose acetate and cellulose nitrate. Because MCE membrane is biologically inert, it’s widely used in analytical and research applications. MCE membrane filter is characterized by smoother and more uniform surface than pure nitrocellulose filter.
Our filters are available in a variety of sizes and membranes that can be easily used for both sterile and non-sterile laboratory applications. Whether your research necessitates prefiltration, sample preparation, sterile filtration, laboratory filtration, or gas venting, Nalgene syringe filters are lab essentials. Key Features. 10 to 100mL
The wwPTFE membrane is ideal for sample preparation and solvent filtration. Extend column life up to 52x. Improve result quality with up to 24% less filter extractables and lower adsorption. Use one membrane filter type for all your sample preparation applications. Hydrophilic wwPTFE membrane also available in two LCMS-certified configurations.
Apply one drop of gastric sample to Gastroccult blood test slide. Observe specimen. If red blood or coffee-ground material is noted, report these findings immediately. Disconnect nasogastric tube from suction. Aspirate 5 to 10 mL with a catheter tip syringe.
Removal of high particulate matter with a glass fiber pre filter is critical before any drug, toxic, or dirty environmental sample is filtered to ensure the highest syringe filter membrane performance. Generally, 0.45 µm porosity filters are used to remove particulates from samples and mobile phase solutions.
