Sartolab RF | BT vacuum filtration units are convenient filtration units designed for research purposes and, therefore, for the filtration of small volumes from > 50 mL to 1 L. These units have the highest flow rates with a large filtration area, no loss of protein with a low protein affinity membrane, and low hold-up volume due to an optimized membrane. They can be used as a stand-alone system or with the Sartolab Multistation, which allows parallel filtration of up to 6 samples.

Membrane made of polyethersulfone (PES) in 3 pore sizes to meet most applications:

• 0.1 µm for mycoplasma removal
• 0.22 µm for the sterile filtration of cell culture, media, buffers, and reagents
• 0.45 µm for the clarification of aqueous and viscous solutions

Sartolab RF vacuum filtration units are comprised of:

• A graduated funnel with a polyethersulfone (PES) membrane, a vacuum adapter and a lid
• A bottle, with graduation and writing field 
• A tube connector for vacuum connection (for stand-alone filtration)
• A screw cap for storage of the filtrate (individually wrapped to maintain sterility)

Sartolab BT bottle top filters are comprised of:

• A graduated funnel with a polyethersulfone (PES) membrane, a vacuum adapter, and a lid
• A tubing connector for vacuum connection (for use as stand-alone)

Sartolab Bottles:

• Delivered sterile, for filtration and storage
