Product Description
FilterMAX™ Syringe Filters, Hydrophilic PTFE, 25mm, 0.22um, case of 500
FilterMAX™ Hydrophilic PTFE Syringe Filters, 25mm, 0.22µm, Case of 500
Standard PTFE filters are hydrophobic and fight you on aqueous samples, forcing extra pre-wetting steps. This FilterMAX™ filter uses a hydrophilic PTFE membrane instead, so it wets out immediately with aqueous solutions while still holding up to the aggressive solvents PTFE is known for.
No hidden fees, ever. Case pricing is straightforward, and ground shipping is always free.
