Conical. Glass Type I / neutral glass as per USP, EP and JP. Autoclavable.

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.

Scope of delivery: 1000 (2000) ml suction bottle with NS 45/40, extension NS 45/40 with hose connection GL 14, PTFE adapter plate, Filter disc D50 (Porosität 2), slit-sieve disc D48, filter funnel 250 (500) ml, clamp (Alu), straight plastic hose connection with seal, threaded cap GL 14

Glass Type I / neutral glass as per USP, EP and JP. Autoclavable.

Useful interface layer between filter paper and perforated Buchner plate. Avoids clogging of filter holes.

With sintered disc filter.

Due to the heavy wall thickness the apparatus is vacuum-tight.

For vacuum or pressure filtration up to 2 bar.
For ultra or sterile filtration.
With collecting bottle 250 ml.
For filter 47mm diameter filters.
