Acrodisc® Syringe Filters, 25mm, Pall® Life Sciences These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility; hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and nonaggressive, solvent-based mobile phases. Polypropylene housing with female Luer-lock inlet and standard male slip Luer outlet connections. All membranes are HPLC certified for low levels of UV-absorbing extractables.
Typical hold-up volume: \<100µL.
Note: PVDF membrane is not for use with acetone, DMF, DMSO, or bases >6N. 货号 Description | Pore Size | Supplier No. | VWR Catalog Number | Unit | | GHP Membrane | 0.2 µm | 4564 | 28139-548 | Case of 200 | | | | | Pack of 50 | | GHP Membrane | 0.2 µm | 4566 | 28139-552 | Pack of 1,000 | | GHP Membrane | 0.45 µm | 4560 | 28143-266 | Case of 200 | | | | | Pack of 50 | | GHP Membrane | 0.45 µm | 4562 | 28139-450 | Pack of 1,000 | | Nylon Membrane | 0.2 µm | 4436 | 28143-946 | Case of 200 | | | | | Pack of 50 | | Nylon Membrane | 0.2 µm | 4522 | 28144-592 | Case of 1,000 | | Nylon Membrane | 0.45 µm | 4438 | 28143-948 | Case of 200 | | | | | Pack of 50 | | Nylon Membrane | 0.45 µm | 4502 | 28144-588 | Pack of 1,000 | | PTFE Membrane | 0.2 µm | 4225 | 28143-926 | Case of 200 现货 | | | | | Pack of 50 现货 | | PTFE Membrane | 0.2 µm | 4521 | 28144-593 | Pack of 1,000现货 | | PTFE Membrane | 0.45 µm | 4219 | 28143-924 | Case of 200 | | | | | Pack of 50 | | PTFE Membrane | 0.45 µm | 4501 | 28144-584 | Pack of 1,000 | | PTFE Membrane | 1.0 µm | 4503 | 28100-062 | Pack of 1,000 | | PTFE Membrane | 1.0 µm | 4226 | 28143-928 | Case of 200 | | | | | Pack of 50 | | PVDF Membrane | 0.2 µm | 4406 | 28143-936 | Case of 200 | | | | | Pack of 50 | | PVDF Membrane | 0.2 µm | 4520 | 28143-280 | Pack of 1,000 | | PVDF Membrane | 0.45 µm | 4408 | 28143-940 | Case of 200 | | | | | Pack of 50 | | PVDF Membrane | 0.45 µm | 4500 | 28144-583 | Pack of 1,000 |
