Sartoguard PES Sartoscale 25 0.2µm | 6pc.

Ready-to-use single-use flat filter for impressive filtration tests of biopharmaceutical liquids to the smallest scale.

• Protection of downstream equipment and final membrane filters
• Bioburden reduction

Sartoguard PES is suited for all, basic membrane prefiltration steps to protect your final membrane filter and downstream equipment. The single-use variants are also available as gamma sterilizable versions.

• More economical process flow
• Downsizing of filtration systems
• Significantly higher total throughput performance
• LRV of 6 per cm² filtration area for Brevundimonas Diminuta and for Serratia Marcescens
• Developed for the execution of reliable filterability samples with 25 mm stamping blades
• Made from the same non-woven fabric material as the original filter cartridges
• Ready-to-use single-use test filter unit

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.

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

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.
