Disposable Filter Funnel

Product Description

Disposable filter funnels

 Microfilt 47 disposable filter funnel for vacuum use is an excellent tool for testing for microbial contamination such as coliforms, fungi or specific organisms. Individually bagged and designed to attach directly to the Pall Gelman aluminum filter funnel manifold , the MicroFunnel is ideal for membrane filtration.

There are two ways to culture a sample filtered with the MicroFunnel: squeezing the top of the cylinder releases the base for easy access to the membrane when plating onto agar or a broth soaked pad. Alternatively the base can be used as a petri dish by placing the clear plastic lid directly on the base. The funnel can also be used on other manifolds by inserting an adapter (supplied) into a rubber stopper.

Funnel bases and cylinders are constructed of polypropylene. Plugs and adapters are polyethylene. The support pad is cellulose laminated to polypropylene, and the clear plastic lid is polystyrene.

Each MicroFunnel is individually bagged, labelled, and sterilized by gamma/ETO  irradiation.

Note: Use with vacuums under 650 MM Hg only.
