Filtering Flask  China
filtering flask, also known as a Büchner flaskvacuum flask, or suction flask, is a type of laboratory glassware designed for filtration under reduced pressure. It has distinct features and specific uses that set it apart from a regular flask.

Specification :

  1. Home Science Tools filter flasks are made from high-quality GG17 borosilicate glass
  2. Low coefficient of thermal expansion means this glass is capable of withstanding typical laboratory temperature variations
  3. Heavy wall construction to withstand 1 atmosphere (760mm Hg) vacuum
    Side hose connection
  4. Markings are accurate to +/-10%

For 250 ml

Height: 13.5 cm.

Diameter: 8.5 cm at base

Neck inside diameter approximately 36 mm

Marked to fill 50-250 mL in 50 mL increments


For 500 ml

Height: 17.5 cm

Diameter: 10.5 cm at base

Neck inside diameter approximately 29 mm

Marked to fill 100-400 mL in 50 mL increments



🔍 Uses of a Filtering Flask:

  1. Vacuum Filtration: Primarily used with a Büchner funnel to perform filtration faster and more efficiently by applying vacuum suction.

  2. Separation of Solids from Liquids: Helps isolate precipitates or particulate matter from solutions.

  3. Sample Preparation: Used in microbiology, pharmaceuticals, and chemistry labs to prepare purified samples for analysis.

  4. Drying Solids: Speeds up drying by removing moisture under reduced pressure.

  5. Crystallization Processes: Sometimes used to collect crystals after cooling and filtering a solution.

     Safety Note: Due to the pressure difference, there's a risk of implosion if the flask is damaged or of poor quality. Always inspect before use and wear proper eye protection.
