Description
BOLA vacuum filtration units provide a complete fluoroplastic assembly for laboratory vacuum filtration of chemically demanding samples. The filtration unit is made of PTFE and includes a multi-stage olive with integrated locking screw for vacuum tubing with inner diameters of 6 and 8 mm, plus a PTFE support disc for optional filter membranes of 47 mm diameter. The receiving vessel and the filling container with slip-on lid are both made of PFA, giving a working volume of 240 ml, an outer diameter of 86 mm and an overall height of 250 mm. Filter area is 13,8 cm². Plasticizer-free construction yields near-universal chemical resistance and avoids release of trace elements into the filtrate, while the anti-adhesive surface simplifies cleaning for repeated use. This 240 ml unit from manufacturer Bohlender is suited to preparative and analytical workflows where glass or conventional plastics are unsuitable. Net weight is 0,838 kg per piece. Membranes are optional and selected separately to match the intended application and pore rating.

Questions about BOLA Vacuum Filters, 240 ml Fully made of fluorplastics (PTFE/PFA) membrane dia.
What is this article?
BOLA Vacuum Filters, 240 ml Fully made of fluorplastics (PTFE/PFA) membrane dia. is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Lab consumables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
