Sterile Syringe Filters: With proven performance, syringe filters are sterile polyethersulfone (PES) syringe filters. batch of syringe filters is certified for HPLC extractable testing. Filter size: Membrane diameter 33 mm, Pore size: 0.22 Micrometres, 50 per pack. Pore structure is suitable for laboratory sterilization of small volume samples. Bacterial Challenge: LRV 7 per lot of 0.22 Micrometre pore size membrane (ATCC 19146, ASTM Bacterial Challenge Test). Less than 0.25 EU/mL or Less than 2.15 EU/equipment () for each batch of equipment pressure required to empty the syringe. High : Larger filter surface area increases flow rate and . It also makes it easier to filter the solution because it reduces the pressure required to empty the syringe. Biosafety: Complies with USPB bioreactivity testing for Class VI plastics. to better the accuracy of the experiment.
