High-Performance Centrifuge Filters in Australia for Laboratory Applications

15, Feb 2026

In modern laboratories, efficient sample preparation is critical to ensuring accurate analytical results and reproducible research outcomes. Whether working with proteins, nucleic acids, enzymes, or biological samples, laboratories require filtration tools that deliver high recovery, consistency, and speed. For researchers and analysts sourcing a reliable centrifuge filter in Australia, CoPure supplies Cobetter centrifugal filtration solutions engineered for precision laboratory workflows.

Cobetter centrifuge filters combine advanced membrane technology with user-focused design, supporting applications across life sciences, biotechnology, diagnostics, and analytical laboratories.

What Is a Centrifuge Filter and Why Is It Essential?

Centrifuge filters, also known as centrifugal ultrafiltration devices, use centrifugal force to separate molecules based on size through a semi-permeable membrane. They are widely used for:

  • Concentration of dilute protein and nucleic acid samples
  • Desalting and buffer exchange
  • Removal of low-molecular-weight contaminants
  • Sample cleanup before analytical techniques such as HPLC and mass spectrometry

Compared to precipitation or evaporation methods, centrifuge filtration offers faster processing times, higher recovery rates, and minimal impact on sample integrity.

Cobetter Briscale™ Centrifuge Filters Supplied by CoPure

CoPure supplies Cobetter Briscale™ centrifugal filters, designed to deliver high protein recovery, low non-specific binding, and reliable performance across a broad range of laboratory conditions.

Focus Product: 4 mL Ultrafiltration Centrifugal Filter with RC Membrane

The Cobetter Briscale 4 mL centrifugal filter is specifically engineered for efficient concentration and purification of biological samples.

Membrane Technology: Regenerated Cellulose (RC)

Regenerated cellulose membranes are widely recognised in laboratory filtration for their hydrophilic nature and exceptionally low protein binding. Cobetter’s RC membrane achieves a protein recovery rate greater than 90%, validated using lysozyme (14.4 kDa) at 0.25 mg/mL after 60 minutes of centrifugation.

This makes RC centrifugal filters ideal for valuable or limited samples where yield preservation is critical.

Design Advantages for Faster, More Reliable Concentration

Cobetter Briscale centrifugal filters feature a vertical membrane design that increases effective membrane surface area while reducing concentration time. This configuration enables:

  • Rapid processing with up to 80-fold concentration
  • Uniform flow distribution across the membrane
  • Reduced membrane fouling compared to angled designs

The translucent housing and clear volume graduations allow users to visually monitor sample concentration throughout the centrifugation process.

Chemical Compatibility and Handling

Cobetter RC centrifugal filters offer broad chemical compatibility from pH 1 to 14, enabling use across a wide range of buffers and sample types. Delivered non-sterile and individually packed, these filters are intended for single-use laboratory applications. Sterilisation is not recommended to preserve membrane integrity.

Key Features That Support Laboratory Efficiency

  • Low-binding RC membrane for high sample recovery
  • Colour-coded caps for easy identification of different MWCOs
  • Clear volume markings for precise monitoring
  • Individually packaged units to minimise contamination risk
  • Pack size: 15 units per box

These features reduce handling errors and improve day-to-day laboratory productivity.

Typical Laboratory Applications

Cobetter centrifugal filters are widely used in:

  • Concentration and purification of proteins, antibodies, antigens, and enzymes
  • Nucleic acid preparation and cleanup
  • Desalting, buffer exchange, and dialysis of protein samples
  • Removal of primers, adapters, or molecular tags after reactions
  • Concentration of pre-purified proteins from chromatography
  • Sample cleanup before HPLC and mass spectrometry
  • Purification of macromolecules from tissue culture extracts or cell lysates

How to Choose the Right Centrifuge Filter

Selecting the correct centrifugal filter depends primarily on molecular weight. A common best practice is to choose an ultrafiltration membrane with a molecular weight cut-off (MWCO) that is 2–3 times lower than the target macromolecule’s molecular weight. This ensures efficient retention while allowing smaller contaminants to pass through.

CoPure’s technical team can assist laboratories in selecting the appropriate MWCO and device configuration based on sample type and application.
