Ready-to-use with No Time-consuming Presterilization or Cleanup Required
Helping you eliminate potential contamination risks is what Pall’s MicroFunnel™ filter funnel is designed to do. Because environmental microorganisms are opportunistic by nature, they readily grow when introduced to a wide variety of aqueous solutions. If left unnoticed, these harmful microbes can result in a significant loss of time, money and productivity.
Our disposable, gamma irradiated MicroFunnel filter funnels come ready-to-use and are individually bagged. These convenient filter funnels provide quality assurance when testing for microbial contamination – especially when employing the MF Technique. Offered in 100 mL and 300 mL sizes, MicroFunnel filter funnels are available in a variety of models featuring a wide selection of membrane options to meet your specific application requirements.

Standard Procedures Using MicroFunnel Plus Filter FUnnels
Analyzing Ambient Samples
|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 base then remove and discard lid.|
|5. Release cylinder from base by squeezing the midpoint of
|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.)
