MicroFunnel - Filter Funnels

• Product performs as sample container and filter funnel all in one. No need to transfer sample from cup to disposable funnel and risk introducing contamination.
• MicroFunnel Plus AP unit allows aseptic collection of the sample through the lid sample port. No need to remove lid.
• MicroFunnel Plus products with Supor™ membrane are designed to allow sampling of hot water up to 90°C.
• Vented lid snaps to a liquid-tight seal and allows filtration without having to open the funnel and risk introducing contamination.
• Vent filter ensures no airborne contamination is drawn into the funnel during filtration.
• Attaches directly to a standard laboratory manifold or use with adapter and stopper.
• Volume graduations are clearly marked for ease in measuring your sample volume.
• Individually bagged and labeled for contamination control and lot traceability.
• NEW Packaging* see Specifications for more information

Applications

• Improves the efficiency of monitoring your water system while reducing the introduction of contamination.
• Eliminates steps in sample collection and testing that could potentially contaminate your sample.
• Gridded 0.45 μm GN-6 Metricel™ membrane is ideal for analysis of ambient water by Membrane Filter (MF) Technique.
• MicroFunnel Plus with 0.45 or 0.2 μm Supor™ membrane is designed for sampling hot water (such as that found in hot loop WFI systems).

Performance

How to Use the MicroFunnel Plus Filter Funnel

• Sampling Ambient Water
• Carefully remove the vented lid and collect the sample.
• Securely snap lid in place to prevent sample loss. Transport sample to laboratory for filtration.
• Remove membrane vent from base, place funnel directly onto manifold, and filter the sample.
• Gently grasp funnel then remove and discard lid.
• Release cylinder from base by squeezing the midpoint of the cylinder.
• Remove the membrane, plate the filter, and incubate.

Collecting Hot Water Samples

• Place funnel into holder with graduations visible through the viewing slot. Carefully remove the vented lid and collect the hot water sample.
• With funnel and holder resting on a firm, level surface, securely snap lid in place to prevent sample loss. Remove funnel from holder and transport sample to laboratory for filtration. (Proceed with steps 3-6 for ambient water.)
