Description générale

The Biopak® Polisher is an ultrafiltration cartridge designed to produce water suitable for molecular biology, biochemistry and cell culture when fed with Milli-Q® purified water. It is validated for continuous use for 90 days.


Biopak® Polisher ultrafiltration cartridge is suitable for use with Milli-Q® IX 7003/05/10/15, Milli-Q® IQ 7000, Milli-Q® IQ 7003/05/10/15 and Milli-Q® EQ water purification systems. Designed for applications such as molecular biology, biochemistry and cell culture (when fed with Milli-Q® purified water), the Biopak® ultrafiltration unit removes macromolecules and larger biological structures, such as bacteria.

Biopak® Polisher is recommended for a wide range of laboratory applications where bacteria, pyrogen, nuclease and/or protease levels must be controlled.
This includes small-interfering RNA (siRNA) research, RNA in situ hybridization, microarray development, or studies of protein synthesis machinery.

Caractéristiques et avantages

  • Minimizes risk of nuclease, protease, pyrogen or bacteria contamination.
  • Eliminates the need for toxic agents such as DEPC, therefore improving safety, saving time and reducing costs.
  • Bottom-tip is redesigned for a secured installation of the protection bell.
  • Easy maintenance: the polisher is easily installed and replaced; does not require sanitization.
  • e-Sure tag for RFID connection with POD enables full traceability (data management) and automatic consumable status monitoring on the POD′s touchscreen interface.
