CLEARLine® Single-Use Vacuum Filtration Systems, PES 0.22 µm

Biosigma’s single use vacuum filter cup is a disposable laboratory filtration system designed for the sterilization and clarification of biological liquids.
The system combines a filter funnel, adapter and collection reservoir in an independent vacuum filtration unit, offering a practical solution for processing large volumes of liquid in professional laboratory workflows.

It is made with a PES filter membrane with 0.22 µm pore size to support efficient filtration, while the high flow rate and high flux help reduce filtration time and improve process efficiency.
The quick-disconnect pre-filter is designed for convenient handling, and the 90-degree orientation between the filter tip and the graduation scale makes it easier to read the liquid level during filtration.

Manufactured under ISO 13485 and ISO 9001 quality management systems, the filter cup is gamma-sterilized to SAL 10⁻⁶, non-pyrogenic and non-cytotoxic.
The product is intended for general laboratory use and is not autoclavable.
