Features

• Built-in prefilter for quick and easy processing of difficult-to-filter samples
• Filtration product with plunger, filter and vial integrated without assembly. Sample filtration and storage are possible in one container, and filtration work is completed quickly and easily. You don't need a syringe.
• A prefilter and membrane are built into the plunger side, and when the sample liquid is put into the test tube and the plunger is pushed in, the pressure is applied and the filtration is completed. The filtrate accumulates in the reservoir inside the plunger.
• It is a product based on the same principle as Mini Uni, but the cap of Uniprep has no septum and can be used for a large amount of samples (1~5 mL).
• To use, lower the plunger tip until it touches the fluid level in the test tube and gently push it to the bottom of the test tube. Then, transfer the filtrate to a sample vial or autosampler vial, or suck it up with a syringe and inject it into the analyzer.
• PTEF: polytetrafluoroethylene. Hydrophobic membrane with excellent chemical resistance, suitable for filtration of organic solvents and acid/basic solutions.
• Note)Refer to "Chemical Resistance by Membrane Material" (PDF) for chemical resistance of materials. Only for test and research purposes.
