Filter flasks, with glass olive, borosilicate glass 3.3
The LABSOLUTE® Erlenmeyer shaped filter flasks with glass olive made of high-quality borosilicate glass 3.3 comply with the ISO 6556 and DIN 12476 standards. Together with the LABSOLUTE® Buchner funnels and suitable rubber gaskets, they form a perfect unit for almost all kinds of filtration applications in chemical labs. All LABSOLUTE® filter flasks are autoclavable and, because of their high wall thickness, also vacuum-proof.
We recommend a vacuum tube with an inner diamater of 8 mm to connect the filter flasks to a vacuum pump.
Due to the glass olive, the flasks do not comply with the requirements of the German product safety law (ProdSG).
