Whatman AV125NPUAQU PVDF Autovial 12 Syringeless Filter, No Prefilter, 0.45 Micron (Pack of 50)

This 12ml Whatman autovial syringeless filter is a preassembled filtration device for removing particulates from samples. It is 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 which protects the recessed slip-luer tip. The autovial filter is selected according to membrane compatibility with the sample. In practice, the sample is poured into the 5ml capacity filter barrel. The plunger is inserted into the barrel until the bottom is securely in place; there is a gap of air between the sample and plunger. The tip of the autovial is placed into the mouth of an autosampler vial or container and the plunger compressed. Filtration begins immediately and, as the plunger is compressed until it reaches the bottom, the membrane is purged with air for maximum sample recovery. For direct instrument injection, a needle is placed on the autovial slip-luer outlet. Prefilter: None. Filtration Media: PVDF. Filtration Area: 3.0 sq cm. Capacity: 12ml. Retention: 0.45µm. 50/Pack.
