Syringeless Filter, Glass Prefilter, Nylon Membrane

Syringeless filters are preassembled filtration devices for removing particulates from samples. They replace syringe-coupled filtration devices with single, disposable units.
Devices are comprised of two parts: a graduated filter barrel and a plunger. The proven design features an integral filter, built-in air purge and a support stand that protects the recessed slip-luer tip. They are available in a 5 mL and 12 mL volume capacity.

Cellulose Acetate (CA): low nonspecific protein binding and high loading capacity membrane for biological solutions
Glass microfiber (GMF): depth filter for samples in aqueous or organic solutions
Nylon (NYL): for aqueous and organic samples within a pH range between of 3 to 10
Polyethersulfone (PES): low non-specific protein binding membrane for samples in aqueous solutions
Polypropylene (PP): Hydrophobic membrane. Resistant to a wide range of organic solvents
Polytetrafluorethylene (PTFE): PTFE membrane for samples with > 50% organic solvent
Polyvinylidene Fluoride (PVDF): low nonspecific protein binding membrane for samples in aqueous solutions and/or organic solvents

Single unit convenience saves time. No assembly required - easier to load
Choice of filter media. Compatible with a wide range of sample types
Ideal for hazardous samples. Self contained device eliminates risk of filter pop-off
Built-in air purge maximizes sample recovery
Sterile option available to maintain sample integrity
Unique prefilter design for difficult-to-filter samples (no prefilter in Autovial 5 and in selected Autovial 12)
Choice of glass fiber or polypropylene prefilters
