Sartorius introduced Sartolab® RF|BT 150-1000 vacuum filtration units that the new design has been improved to offer greater capacity and speedier and greater physical stability for a wide range of sample types.

Design modifications include:

1.An increase of the membrane surface area to facilitate optimal filtration

2.Replacement of the 0.45 μm cellulose acetate membrane with a 0.45 μm polyethersulfone

3.membrane to increase the flow rate while keeping the same low protein binding properties

4.An optimized center of gravity to increase stability of the units

5.Direct use on the Sartolab® Multistation for parallel filtration

“We are excited to introduce our updated Sartolab® vacuum filtration units which build upon the benefits and ergonomic design of the original units,” said Catherine Leluan, Product Manager. “The redesign of these units exemplifies our commitment to engineer products that accelerate and streamline workflows, are user-friendly and are well-suited for the busy laboratory setting. In addition, improvement in our manufacturing controls are expected to lead to increased robustness of supply to help meet growing market demand.”

Sartolab® RF|BT vacuum filtration units are made to be used for research and for filtration of small volumes ranging from 50 mL up to 1L. Sartolab® RF units come with a receiver flask that connects to the filtration funnel. The Sartolab® BT design includes only the bottles top filter (filtration funnel) that allows users to make use of their own flasks to filter their receivers, and/or increase the filtration capacity according to the amount of particles in the liquid that is being filtered by filling multiple flasks for receivers.

1.Redesigned units provide faster, higher capacity and greater physical stability for a wide range of sample types

2.Larger membrane surface area facilitates optimal filtration

3.Use of polyethersulfone membrane in the 0.45 μm pore size filter increases the flow rate with the same low protein binding properties

These filtration units provide the best flow rates and have huge filtration areas and a low affinity protein membrane that minimizes loss of protein and a membrane that is optimized for a smaller hold-up volume.

The Sartolab® RF|BT vacuum filtration units are available in three different pore sizes to meet most of the applications:

1.1 μm for mycoplasma removal

2.22 μm for sterile filtration of cell culture media, buffers, and reagents

3.45 μm for clarification of aqueous and viscous solutions

Sartolab® RF|BT products are now manufactured in a new plant designed to meet growing market demand for vacuum filtration units. The plant is ISO 13485 certified, and an ISO Class 8 cleanroom assures the highest level of sterility.

Improved efficiency of logistics during manufacture combined with improved storage processes has reduced the carbon footprint required for global distribution of these units by 99%.
