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.

Optimal Design for Laboratory Needs

Disposable Filter Funnels feature a conical shape and are constructed from robust polypropylene for high chemical resistance. The integrated filter support (if specified) streamlines filtration workflows, aiding efficient separation of solids from liquids. The standard neck compatibility ensures seamless integration with laboratory flasks, while the range of available sizes (50 mm to 150 mm diameter) provides flexibility for various sample volumes.

Single-Use Convenience and Safety

Designed for single-use applications, these filter funnels minimize the risk of cross-contamination in sensitive laboratory environments. Pre-sterilized options are ideal for microbiology and analytical testing, ensuring sterility from the packaging. Their disposable nature simplifies cleanup, making them an excellent choice for fast-paced laboratories. Both bulk-pack and individually wrapped packaging suit different throughput and sterility requirements.

FAQ's of Disposable Filter Funnel:

Q: How do I select the appropriate size of disposable filter funnel for my application?

A: Choose a funnel size (50 mm to 150 mm diameter) based on your flask neck size and the volume of liquid you need to filter. Capacities typically range from 100 mL to 500 mL, making them suitable for most laboratory filtration needs.

Q: What are the benefits of using pre-sterilized disposable filter funnels?

A: Pre-sterilized funnels offer assurance of sterility for sensitive applications such as microbiology and analytical testing. They help prevent contamination, reduce preparation time, and eliminate the need for extra sterilization steps.

Q: Where are disposable filter funnels typically used?

A: These funnels are primarily used in laboratories for filtration, separation of solids from liquids, and in microbiological or analytical testing processes. Their compatibility with standard laboratory glassware makes them versatile for various industries.

Q: When should I choose individually wrapped funnels over bulk packed ones?

A: Individually wrapped funnels are suitable when sterility must be maintained until the point of use or when cross-contamination risk is high. Bulk packaging is ideal for high-throughput labs where funnels are used frequently and sterility is less of a concern.

Q: What is the process for using a disposable filter funnel in laboratory filtration?

A: Place the funnel onto a compatible flask, pour the sample into the funnel, and allow filtration to occur. If the funnel includes integrated filter support, it secures the filter in place. Dispose of the funnel after use to maintain a contamination-free environment.

Q: Can these disposable filter funnels withstand autoclaving?

A: Yes, the polypropylene material is temperature resistant up to 121C, making the funnels suitable for autoclave sterilization, if required, for non-sterile versions.
