This Filtering Flask with Standard Ground Mouth is made using high-grade borosilicate 3.3 glass, which is known for its excellent thermal, chemical, and mechanical strength. It is professional-grade conical flask designed to meet laboratory filtration requirements. It has a thick-walled body and reinforced neck, which allow for safe and efficient vacuum filtration in educational and industrial laboratories.

Rubber stoppers, funnels, or adapters that are compatible can seal to the standard ground mouth allowing for reliable setups to enable filtration through reduced pressure or gravity.

Feature Of  Filtering Flask

● Vacuum Pressure With No Risk Of Cracking: Designed for strong wall thickness conditions.

● Universal Lab Use: Ground joint compatible with several different filtration devices.

● Greater Clarity and Borosilicate Glass Durability: Filtered high acid or alkaline procedures use for round glass.

● Customization Without Original Manufacturing: Ability to customize volume markings, branding, and size.

● Improved Efficiency: A airtight sealing from ground mouth improves filtering effectiveness.

Specitication Of Flask

Application Of  Lab Glassware Conical  Flask

● Chemical Laboratories

Used for vacuum or gravity filtration of suspensions, precipitates, and chemical residues. Commonly paired with Buchner funnels, filter paper and vacuum pumps to isolate solids from liquids with high purity.

● Microbiology and Biological Labs

 Frequently Asked Questions (FAQ)

What’s the primary application of a Filtering Flask Standard Ground Mouth within a laboratory setting?

The Filtering Flask with a Standard Ground Mouth is often utilized for vacuum or gravity filtration in chemical and biological laboratories. Its ground joint permits the strong sealing with Büchner funnels or other adapters, which makes it good for safe and effective solids liquid separation.

In what way is this filtering flask different from a conical flask from the laboratory glassware collection?

The filtering flask is different from laboratory glassware conical flask because it has reinforced walls and a ground glass neck which is a feature for vacuum pressure filtration on the filtering flask. It is designed for higher level pressure operations typical in advanced scientific laboratories.

Is it possible to use this flask with 250ml volumetric flasks when preparing solutions?

Yes, this flask can be used as a controlled funnel setup with volumetric flasks for filtering into or out of the flasks. Its clear body allows accurate transfer and contamination-free manipulation, while its tight sealing provides exceptional protection from contamination.
