General description

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.

Application

Biopak® Polisher is recommended for a wide range of laboratory applications such as molecular biology, cell culture and biochemistry, where bacteria, pyrogen and/or nuclease levels must be controlled. This includes bloodstream bacterial infections (BSIs) research, electrochemical biosensor development, endotoxin adsorption studies, antimicrobial testing and mRNA and protein detection.

Features and Benefits

  • Minimizes risk of nuclease, pyrogen and bacteria contamination.
  • Eliminates the need for toxic agents such as DEPC, therefore improving safety, saving time and reducing costs.
  • Care-free maintenance: The polisher is easily installed and replaced; does not require sanitization.

Water for Nuclease-sensitive Molecular Biology Studies

Nuclease-free water (or PCR water) is needed in molecular biology to avoid sample degradation during PCR, sequencing, etc. Ultrafiltration provides a quicker, safer, and more sustainable alternative to DEPC treatment when preparing RNase-free and DNase-free water.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
