DORSAN® syringe filters, manufactured with naturally hydrophobic Polytetrafluorethylene membranes (PTFE). This is the type of membrane most widely used in the preparation of samples for HPLC analysis. PTFE is widely used due to its great resistance to the majority of acid, alkaline and solvent products. Chemically and biologically inert, they
Step 2: Attach a syringe filter to the Syringe. Open the syringe filter package so that you can later pick the filter up easily, especially for individually packed sterile syringe filters. a. For sample volume < 10 mL. Draw a small amount of air (about 1 mL) into the syringe before loading the sample solution.
Polypropylene, nylon, and PTFE membranes are ideal for sample preparation and small volume chemical filtration.Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common
Hold the syringe with the filter pointing up and “top off” by pushing a few drops through the filter. Place the filter tip over the collection container and push the sample through a syringe filter by applying gentle positive pressure. To purge the syringe filter and maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reattach the filter and push the plunger to force some of the air through the filter.
