Henderson Biomedical recommend the following:

Full complement of buckets

Always run with a full complement of buckets. Never run a centrifuge with buckets missing as this will lead to imbalance problems.

Distribute the load evenly

Distribute the load evenly around the rotor to avoid unnecessary strain on the motor shaft or bearing housing. Each bucket should be within 5 grams.

Regularly decontaminate the device and it's accesories

Devise a schedule to regularly decontaminate your rotor, buckets and adaptors. Decide on who will clean the accessories and on which day. If there is a spillage during centrifugation, this should be cleaned up immediately and not left until the next cleaning day.

Use a soft brush

Use a soft brush for cleaning in those hard to reach places. Avoid using a brush with wire bristles which can damage the anodising on the rotor and lead to rusting.

‘O’ rings

Remove ‘O’ rings when cleaning to ensure there is no bacteria trapped in the seal.

Dry all accessories

Dry all accessories immediately after cleaning with a soft, dry cloth. This will prevent to prevent corrosion.

Anti-corrosion spray

Once buckets are dried, evenly spray all areas with an anti-corrosion spray. Henderson Biomedical can supply you with the appropriate anti corrosion spray.

Ensure everything is securely fitted

Ensure rotor, rotor nuts, buckets and windshield lids are securely fitted when in operation. Rotors that haven’t been tightened properly or lids that haven’t been secured can lead to a disruption and a big repair bill.

Never run a windshield rotor without the lid

The spinning action of the rotor will mimic a helicopter and try to break away from the shaft or bearing housing. This will cause considerable damage to your rotor and centrifuge itself.

Broken tubes

If any tubes break during centrifugation, this should be cleaned up immediately before the next run is carried out.

Refrigerated centrifuges

When using refrigerated centrifuges, you should leave lid open after use to allow any moisture to evaporate. This will prevent corrosion.

Replace after 10 years or 30,000 cycles

As a general rule of thumb, rotors and buckets should be replaced after 10 years or 30,000 cycles (whichever the greater). However, the user should take into account how well the accessories have been cared for over time and the type of materials being centrifuged. For example, more corrosive or messy materials may degrade the accessories more quickly.

Damaged elements

Always replace rotors and buckets if they are damaged.

It is important to also regularly service your centrifuge depending on how much you use it. For most people, a single, annual service is sufficient, but for heavy centrifuge use, two service visits may be required.

As with a car, an annual service can extend the life of your centrifuge and ensure safety for the users. A regularly serviced centrifuge will be more reliable in the long term.

Henderson Biomedical also recommends that users are trained on how to properly use a centrifuge. Untrained and inexperienced centrifuge users can be potentially hazardous. We can offer users comprehensive training on centrifuge use.
