Pezafilter
Product Code : SCL-BLE-11663
Pezafilter (SKU SCL-BLE-11663) is a 50 mm bottle top filter: a polystyrene funnel with an integrally welded filter membrane, designed to filter liquids directly into sterile glass media bottles. It comes with an emery (corundum) cover. It suits microbiology, biology and chemistry teaching labs that prepare filtered solutions and media. Science Lab Supplies supplies it out of Ambala, India for schools, colleges, training institutes, tender contractors and distributors sourcing biology lab equipment in India.
Specifications
The table lists each specification of the 50 mm Pezafilter. In short, it is a polystyrene funnel whose filter membrane is welded in place, made to sit on a glass media bottle so the filtrate runs straight into it, and closed with an emery-finished corundum cover.

Applications and Experiments for the Pezafilter Bottle Top Filter
Despite its name, the Pezafilter is a bottle top membrane filter, not a separate filter paper or apparatus. It sits on a glass media bottle so that a solution passes through the welded membrane and collects in the bottle, reducing transfers between vessels in culture-media and reagent preparation.
- B.Sc. microbiology: filtering heat-sensitive solutions into glass media bottles during culture-media preparation.
- Chemistry and biochemistry practicals: clarifying buffers and reagent solutions before use.
- Water-quality teaching: filtering water samples and comparing them with gravity filtration through a glass Funnels and paper.
- Preparing filtered distilled water drawn from a Mariot Bottle (for Distilled Water).
The membrane pore size, the bottle thread it fits and the connection needed for filtration are confirmed on the quotation, so the filter can be matched to your media bottles.
Standard Scope of Supply
Each Pezafilter comprises the 50 mm polystyrene funnel with its welded filter membrane and the emery (corundum) cover. Glass media bottles and any vacuum source are not included; they can be listed on the same quotation so the filtration set-up is complete.
Packing, MOQ and Lead Time
Ask for a quotation for a few filters for a trial practical or a quantity to last a full term. It lists packing, delivery time and price for the chosen quantity, and media bottles, filter flasks or filter paper can be added to the same quotation.

Frequently Asked Questions
What is a bottle top filter?
It is a funnel with a filter membrane built in, made to sit on top of a bottle. Liquid poured into the funnel passes through the membrane and collects directly in the bottle beneath, so no separate receiving flask is needed.
What size is the Pezafilter?
The filter has a 50 mm diameter. The funnel is polystyrene with an integrally welded membrane, and an emery (corundum) cover closes it. Bottle thread and pore size are confirmed with the quotation.
How does it compare with filter paper in a glass funnel?
Filter paper in a funnel suits simple gravity separations of solids. A membrane bottle top filter is used when a solution must pass straight into a clean media bottle, as in culture-media and reagent preparation.
Who supplies the Pezafilter?
Science Lab Supplies supplies it from Ambala, India, and can quote it with media bottles, filter flasks and funnels for a microbiology or chemistry preparation room.
