MicroFunnel™ Plus Filter Funnels

Revolutionizes Water System Monitoring
to Eliminate the Risk of Contamination

• 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 ºC.
• 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.

• 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).

MicroFunnel Plus Filter Funnel Features

Save yourself time, avoid sample contamination or mix-ups, and reduce the steps in sample collection and testing.

How to Use the MicroFunnel™ Plus Filter Funnel

Sampling Ambient Water

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

 

Collecting Hot Water Samples

1. Place funnel into holder with graduations visible through the viewing slot. Carefully remove the vented lid and collect the hot water sample.
   
2. 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.) 
   

Note: When using this product for sampling hot water, observe safety precautions which include the use of insulated rubber gloves, safety glasses, and Pall Life Sciences funnel holder (PN 4824 for 100 mL funnels and PN 4825 for 300 mL funnels).
