Filtration apparatus

These bottle-top filter units are ideally suited for the separation or purification of samples which are contained in large volumes. The units are available with either 0.22 µm or 0.45 µm pore sizes and 3 different volumes (250, 500 and 1000 ml).
Features:

• Bottle-top filter and reservoir bottle are included
• Light weight and stable wall construction
• Large knurls on the reservoir bottle cap for easy screwing
• Wide bottle mouth for efficient pouring out
• Volume graduation
• Hose connector fits multiple diameters
• Pyrogen-free
• Membrane material: Polyethersulfone (PES)

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.
