Sartolab® BT Bottle Top Filters (Sartorius) are filtration funnels without a receiver flask, enabling customers to use their own receiver flasks and/or to expand the filtration capacity, depending on the particle load of the filtration liquid, by filling more than one receiver. Filters 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® BT bottle top filter is comprised of a graduated funnel with polyethersulfone (PES) membrane, a vacuum adapter and a lid, and tubing connector for vacuum connection (fur use as stand-alone).

The ergonomic design of the 150mL to 1L bottles (optional; sold separately) 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.
