Filtration apparatus

The LABSOLUTE® filter crucibles are made of borosilicate glass 3.3 and are therefore extremely resistant against high temperatures and chemicals. The crucibles are autoclavable and can be perfectly used for applications in qualitative analysis and preparative chemistry. The sintered glass filter disc has a porosity of 4 which equals a pore size of 5 -15 µm.

The LABSOLUTE® Buchner funnels are made of high-quality porcelain and comply with DIN 12905. They are glazed on the inside and outside and are characterized by an excellent resistance to lyes and acids with the exception of hydrofluoric acid.

The LABSOLUTE® Erlenmeyer shaped filter flasks with glass olive are made of high-quality borosilicate glass 3.3 and comply with ISO 6556 and DIN 12476. Together with the LABSOLUTE® Buchner funnels and suitable rubber gaskets, they form a perfect unit for almost all kinds of filtration applications in chemical laboratories. 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).

Filter plates must be ordered separately.

The DURAN^® filtering apparatus is made of high-quality borosilicate glass. Aside from glass, the medium only comes into chemical contact with PTFE. This means that the filtering apparatus can be used to filter virtually any chemical. Thanks to the PTFE disc holder, fritted glass discs of different porosities can be used in addition to the slit-sieve disc. This creates a wide application scope for filtration using filter paper, membrane filters (47mm) or simply using glass filters. Different porosities are available between 10µm and 160µm, which makes it possible to perform coarse and fine filtration in addition to analytical filtration. Furthermore, the filtering apparatus is suitable for the filtration of HPLC media, testing for bacterial contamination, residue analysis and the filtration of other media.
