This 12ml Whitman autodial syringe less 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-lure tip. The autodial 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 autodial is placed into the mouth of an auto sampler 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 autodial slip-lure outlet. Profiler: None. Filtration Media: PVDF. Filtration Area: 3.0 sq. cm. Capacity: 12ml. Retention: 0.45µm. 50/Pack.
