FilterMAX™ Syringe Filters, Glass Filter, 25mm, 1.0um, case of 1000

Glass fiber syringe filters earn their place in the lab by handling the dirty work -- literally. This 25mm filter uses a 1.0 µm glass fiber membrane built to clear high-particulate aqueous samples fast, without clogging halfway through your run...

FilterMAX™ Syringe Filters, Hydrophilic RC, 25mm, 0.22um, case of 1000

HPLC vials with ghost peaks from filter extractables are one of the most frustrating troubleshooting rabbit holes in the lab. FilterMAX regenerated cellulose syringe filters have extremely low extractables and broad solvent compatibility, so what shows...

FilterMAX™ Syringe Filters, Hydrophobic PTFE, 25mm, 0.22um, case of 1000

Strong acids and aggressive solvents will eat through a lot of filter membranes before they're done with your sample. FilterMAX hydrophobic PTFE syringe filters are built for exactly those harsh chemistries, giving you the broadest chemical resistance of...

FilterMAX™ Syringe Filters, Hydrophobic PVDF, 25mm, 0.22um, case of 1000

Filtering organic solvents through the wrong membrane is a fast way to ruin both the filter and your sample. FilterMAX hydrophobic PVDF syringe filters are built to handle solvents and gases that would tear through a standard hydrophilic membrane,...

FilterMAX™ Syringe Filters, Nylon with Glass (GF) Prefilter, 25mm, 0.22um, case of 1000

Dirty samples shorten the life of a standard membrane filter fast. This 25mm nylon filter solves that with a built-in glass fiber prefilter layer that catches heavy particulate before it ever reaches the 0.22 µm nylon membrane, so you get longer...

FilterMAX™ Syringe Filters, Nylon, 25mm, 5.0um, case of 1000

A 25mm nylon syringe filter is the workhorse you reach for when sample volume is small but precision still matters. This 5.0µm membrane removes particulates and microorganisms from your sample before it ever reaches the column or instrument, and...

FilterMAX™ Syringe Filters, Polypropylene, 25mm, 0.45um, case of 1000

Polypropylene membranes are the go-to when your sample is aggressive or your solvent list is long. This 25mm filter pairs a 0.45 µm polypropylene membrane with a polypropylene housing for broad chemical compatibility, so you're not stuck checking...
