Filtration apparatus

To DIN 12905.

White, cellulose nitrate membrane. Colour code: green. Gamma-irradiated sterile. Highest throughput rate for water and aqueous solutions, low extractables content. Surfactant-free. Lot number, catalogue number, membrane type, pore size and expiration date are printed on filter units, bottle tops and receivers for easy identification and lot traceability.

With glass rim. For use in dismountable filter holders. Patented design. Filter discs must always be screwed in between two FKM rubber seals. Without top manifold, PP outlet funnel or seals.

DIN 12476. ISO 6556. With PBT tubing connection and silicone (VMQ) seal. Heavy wall for vacuum use. These filtering flasks fulfil the regulations of the equipment and product safety regulations.

Buchner pattern funnel with slotted sieve (perforated) filter plate. 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

Graduated reusable filtration unit bodies with upper manifolds and lower receivers made of unbreakable polysulphone (PSU). Nominal filtration surface 11cm². With membrane support plate. Without membrane. For filter membrane from 47mm to 50mm.

Ready-to-use pressure filtration capsules for sterile filtration of media and aqueous solutions with volumes of up to 20 litres (Sartobran 150), or 40 litres (Sartobran 300). The units consist of a polypropylene housing containing a double-layer cellulose acetate membrane (0.2 µm and 0.45 µm). The membranes, which have an area of 150 cm² or 300 cm², have extremely low protein adsorption levels. Autoclavable at up to 134°C. Automatically air vented via an integral PTFE membrane. Sterile and individually packed. With 6 to 12 mm flexible tubing connections (SO) or 1/2 inch tri-clamp (TC).

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

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