Erlenmeyer-Style Büchner Flask Borosilicate 3.3

Büchner flask manufactured in LBG borosilicate 3.3 glass. The Erlenmeyer profile combines bench stability with the ability to swirl the filtrate freely. The side tubulation connects directly to a vacuum line or water aspirator.

Features

• Material: LBG borosilicate 3.3 glass
• Profile: Erlenmeyer with side vacuum tubulation
• Chemical resistance: High — suitable for acids, bases and common laboratory solvents
• Autoclavable: Yes

Applications

Vacuum filtration with Büchner funnel or sintered glass crucible. Also used as a collection flask in reduced-pressure distillation setups. Standard in chemistry laboratories, quality control and sample preparation.

The Erlenmeyer profile — unlike the flat-bottom Büchner flask — allows swirling the filtrate between cycles without splashing at the mouth.

Technical Data

• Material: Borosilicate 3.3 (LBG)
• Type: Erlenmeyer-style Büchner flask
• Tubulation: Side, for vacuum connection
• Autoclave: Yes, 121 °C

Assembly and Compatibility

Connect the side tubulation to a vacuum pump or water aspirator using standard rubber or silicone tubing. The mouth accepts a Büchner funnel with a rubber adapter. The flask stands directly on the bench — the Erlenmeyer base is stable without additional support.
