Sartolab® RF Vacuum Filtration Units (Sartorius) are convenient filtration units designed for the filtration of small volumes from >50 mL to 1L. Units are manufactured in an ISO 13485 certified plant and ISO Class 8 cleanroom to ensure the highest level of purity. All fluid path materials used in products are medical graded for highest quality, without any animal origin, are determined to be non-cytotoxic in accordance to ISO 10993, and meet the requirements for United States Pharmacopeia (USP) Class VI Biological Test for Plastics, latest volume.

The Sartolab RF is a complete system from receiver funnel to the filtration funnel. Each unit is comprised of a graduated funnel with a polyethersulfone (PES) membrane, a vacuum adapter and a lid, a bottle with graduation and writing filed, a tube connector for vacuum connection (for stand-alone filtration), and a screw cap for storage of the filtrate (individually wrapped to maintain sterility).

The ergonomic design of the 150mL to 1L bottles allow for easy gripping with one hand and are designed with a writing field on the back for clear labeling of samples. Engraved graduation on the funnels and the bottles ensures accuracy and the highest readability. The footprint of the bottles gives good stability for the unit during filtration and no extra tightening of the funnel before filtration is required (vacuum-tight sealed).

• Risk of contamination is minimized by the complete read-to-use RF unit
• Highest flow rate with a large filtration area
• No loss of protein with a low protein affinity membrane
• Low hold-up volume due to an optimized membrane support
• Can be used as stand-alone system or with Sartolab® Multistation, which allows parallel filtration of up to six (6) samples
• Choose from 0.22µm or 0.45µm (and 0.1µm for RF250 and RF500)
• Funnels and bottles are stackable to save space in the refrigerator and on the bench
• Sold sterilized and guaranteed endotoxin-free
