Sterile Syringe Filters: Made for performance, syringe filters are sterile polyethersulfone (PES) syringe filters. batch of syringe filters is certified for HPLC extractable testing. Filter Size: Membrane Diameter 33mm, Pore Size: 0.22 Micrometre, Pack of 10. Pore structure suitable for laboratory sterilization of small volume samples. Bacterial Challenge: LRV 7 per lot of 0.22um pore size membrane (ATCC 19146, ASTM Bacterial Challenge ). 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. Colour:green Material: pes Package Contents: 10 x Syringe Filters Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
