Sartolab® RF | BT vacuum filtration units are designed for research purposes, and therefore for filtering small volumes from 50 ml to 1 L. Sartolab® RF as a complete system includes a flask to receive the filtrate to the filtration funnel. Sartolab® BT is a filter at the top of the bottle (filter funnel) without a flask, which allows users to use their own flasks and/or expand the filtration capacity, depending on the particle load of the filtered liquid, by filling more than one flask.

User benefits:
- highest flow rates with an asymmetric membrane and a large surface of filtration
- no loss of proteins with a very low protein binding membrane
- low dead volume thanks to an optimized membrane support
- flexibility to use any bottles suitable for vacuum with a neck size of 45 mm
