Product Category Description:

Ideal for monitoring purified water systems maintained at temperatures up to 90°C (194°F). Filter funnels include sample container and filter funnel in one, which eliminates the need to transfer sample from cup to disposable funnel and protects critical samples from contamination. Funnels have a leakproof, vented lid to guard against spillage of samples during transport combined with an integral membrane seal and squeeze separation of cylinder from base for easy access to the membrane.

Funnels come with GN-6 mixed cellulose ester membrane or Metricel* black modified polyethersulfone membrane for sampling ambient purified water systems. Use filter funnels with Supor* polyethersulfone membrane for hot water sampling such as hot loop water for injection.

MicroFunnel Plus AP filter funnels allow for aseptic collection of a sample through the sample port on the lid of the filter funnel, without removal of the lid. Filter holders are recommended for use when collecting hot water samples.

Gamma irradiation sterilized.

Ordering Information: Filter funnels are individually bagged. Filter funnels 28143-570 and -580 are not compatible with hot water applications; for use with ambient temperature samples only. Sterile sampling tubes for MicroFunnel Plus AP Filter Funnels are sold separately; contact our sales representative for more information.
