Sartobran® P | Sartoscale 25 | 0.2µm | 6pc.

Sartobran® P with its unique low-binding cellulose acetate (CA) membrane is mainly used for the sterile filtration of blood & plasma products and vaccines. The ultra-low binding of the membrane material leads to highest product yield and exceptional filtration performance. Especially large, shear-stress sensitive proteins do not lose their structure and function when filtered through this special membrane. This will improve your product yield even further.

Main Applications

• Coagulation factors, Albumin, lgG
• Bacterial, viral & mRNA-based vaccines
• Bioprocessed pharmaceuticals
• Ophthalmics
• Purified protein solutions
• Biological fluids
• Fluids containing preservatives

SartoScale units are ideally suited for all types of filterability studies with the aim of selecting the optimal prefilter for an optimal application. Moreover, they can determine the ideal combination of pre- and final filters with the aid of a minimum product volume.

• Developed for the execution of reliable filterability samples
• Made from the same non-woven fabric material as the original filter cartridges
• Ready-to-use single-use test filter unit

Membrane

Sartobran^® P uses a double membrane made of Cellulose Acetate

SartoScale units contain the original filter active material of the corresponding filter cartridges to ensure the repeatability of test results.

Flexibility

Sartobran^® P filters are available in different sizes and formats with corresponding filter areas from 4.5 cm² up to 1.8 m². Different connections allow easy integration into existing systems.

Using SartoScale during filtration studies saves time which would otherwise be used for the installation preparations for the punch piece in the stainless steel filter brackets and prevents possible installation errors.

After the material selection or the definition of a pre/final filter combination with the SartoScale units, a scale-up method should be carried out for the flow rate and total flow using pleated capsule units of small scales (e.g. capsule size 4).

SartoScale units have an extremely low residual volume for performing filterability samples with minimized product volumes.

SartoScale test filter units are equipped with suitable filter membranes for integrity testing so that their integrity can be determined using the bubble point test in order to ensure absolute reliability of the test results.

We recommend using the SartoScale units together with the Zero-T Filter Test System to make the filtration studies as effective as possible. The Zero-T system consists of hardware and software modules which make it easy to handle and install Sartoscale test filter units. Automatic data collection is achieved by connecting a frame to a laptop. The software automatically analyzes the incoming data for the scale-up calculations.
