At CoPure, we’re proud to bring Cobetter’s world-class centrifuge filters to Australian researchers, biopharma labs, and diagnostic facilities. Engineered for high-speed separations and ultra-low protein binding, Cobetter filters are trusted in demanding applications—where every drop matters.
Why Choose Cobetter Centrifuge Filters from CoPure?
Low protein binding & high recovery rates
Cobetter’s ultrafiltration centrifugal filters — for example, the 2 mL unit with regenerated cellulose (RC) membrane — report a protein recovery rate of over 90 % when using lysozyme (14.4 kDa) at 0.25 mg/mL and centrifuged for 60 minutes.
For Australian labs where precious samples such as proteins, antibodies or viruses must be recovered with minimal loss, this performance is key.
Wide range of pore sizes & membrane materials
Cobetter’s filters come in a variety of molecular-weight cut-offs (MWCO) — e.g., 3 kDa, 10 kDa, 30 kDa, 50 kDa, 100 kDa for the 2 mL unit.
Although your blog brief mentions pore sizes 0.1 µm, 0.22 µm, 0.45 µm, these correspond more to sterile/clarification filters rather than ultrafiltration membranes. In either case, Having a broad choice lets labs tailor the filter to their sample size, whether it’s nucleic acids, viral particles, or concentrated proteins.
Advanced membrane materials
Cobetter employs membranes such as RC (regenerated cellulose), which have very low protein adsorption and broad chemical compatibility (pH 1-14 for many models).
Some designs also use PES or PVDF membranes depending on the chemical/biological challenge at hand.
Sterile and non-sterile options
Depending on your workflow—whether it’s cell culture clarification, viral filtration, DNA/RNA purification or standard protein concentration—Cobetter offers sterile-grade units or non-sterile options. Their broader filtration portfolio shows they support sterile workflows.
In the Australian context, with strict lab accreditation and regulatory requirements, this versatility matters.
Trusted brand, local supply
Cobetter is a globally recognised name in filtration, with ISO 9001-certified manufacturing and validated product lines.
At CoPure, you gain local access to these products in Australia — meaning faster shipping, no long overseas waits, and technical support tailored to the ANZ region.
Ideal for These Applications
Because of the performance and flexibility of Cobetter centrifuge filters, they are an excellent fit for:
Cell culture clarification (removing cell debris after harvest)
Microbial/viral filtration (especially when you need low binding, high recovery)
DNA/RNA purification workflows (ultrafiltration instead of just simple spin columns)
Protein separation & concentration (especially when sample amounts are precious)
Clinical diagnostics labs where sterility, traceability, and repeatability are key
Why CoPure? (And Why It Matters in Australia)
Filtration experts you can rely on
We’re more than just a supplier — we’re your technical partner in the lab. Need help choosing the right Cobetter filter (e.g., deciding MWCO, membrane type, starting volume vs concentrate volume, rotor compatibility)? Our team is here to assist.
Australia-wide delivery
Shipping from our Melbourne facility means you avoid long lead times, customs surprises, or overseas freight delays. For time-sensitive projects in Melbourne, Sydney, Brisbane, Perth or beyond, this is a big advantage.
Bulk orders & custom quotes
Whether your facility is a university research group, a diagnostic laboratory, or a biopharma company scaling up protein purification, we support bulk orders, custom packaging, and quotes tailored to your budget and timeline.
Key Specs at a Glance
Filter volumes: e.g., 2 mL units with effective membrane area ~1.4 cm².
High concentration ratios: e.g., up to ~80-fold concentration from dilution.
Excellent compatibility: e.g., RC membranes with a broad pH range.
Rotor compatibility: fixed angle + swing bucket rotors up to ~4 mL sample.
Practical Tips for Australian Labs
Match MWCO to your target molecule: As Cobetter recommends, select an ultrafiltration unit with an MWCO ~2-3 times smaller than your target molecule’s size for optimal retention.
Consider rotor type & maximum g-force: Check your centrifuge rotor compatibility (fixed-angle vs. swing-bucket) and the g-force requirement. Some units specify a maximum of 7,500 g (e.g., 2 mL unit) for optimal performance.
Avoid reuse unless validated: Cobetter indicates single-use is recommended; while some users may try reuse, recovery may drop or membrane integrity may change.
Check sample volume and concentrate volume: Knowing your starting volume and desired concentrate volume helps pick the correct unit (2 mL vs 15 mL etc).
Pre-check chemical compatibility: Although RC membranes have broad pH tolerance, if you have unusual solvents or high ionic strength, confirm compatibility.
In the fast-paced world of Australian biomedical research, diagnostics and biopharma, you need filtration consumables that deliver repeatable, high-yield, and low-artifact results. The Cobetter centrifuge filters we supply at CoPure combine premium membrane design, a wide array of formats, and local support — making them an excellent choice for any lab seeking to elevate their centrifuge-filtration workflow.
If you’re looking for a centrifuge filter in Australia and want a partner who understands your lab’s demands, talk to CoPure today. Let’s help you choose the right Cobetter filter for your application, get it delivered quickly, and get your research or production moving with confidence.
