Nonsterile Syringe Filters provided by STE-Mart are composed of nontoxic, Triton-free membranes which are integrally sealed within overmolded polypropylene housing to ensure durability, eliminate bypass and minimize fluid loss. Low hold-up volume helps maximize the recovery of sample after filtering. These syringe filters can be used with both slip-fit and locking-type Luer syringes as well as standard hypodermic needles.
