Maximize personal safety and protect your investment by ensuring the long life of your equipment with Beckman Coulter’s Field Rotor Inspection Program (FRIP). FRIP inspections are free and designed to prevent premature rotor failure due to stress corrosion, metal fatigue, and wear or damage to anodized coatings.

How FRIP Works

A certified Beckman Coulter Service Specialist will visit your lab and examine all of your rotors. This includes rotor scoping of all cavities for signs of wear and deterioration. Our specialists will also provide recommendations for replacement of over-speed disks and lubrication of all O-rings and threads as necessary.

A formal training session is also available so that you can learn about proper rotor care and handling, avoiding rotor damage, and the significance of safe and proper laboratory practice.

Observing operating procedures and precautions provided in individual rotor manuals helps optimize your separation results and ensures the safe and long-lasting operation of your centrifugation systems.

Implementing the following care and maintenance recommendations will help keep service requirements and downtime to a minimum.

  1. Inspect the rotor at least monthly–especially inside the cavities and buckets–for rough spots, cracks, pitting, white powder deposits (on aluminum rotors) or heavy discoloration. If any of these signs are present, discontinue rotor use.
  2. Regularly check the condition of O-rings and replace any that are worn or damaged. Otherwise, replace O-rings as required. For heavy usage, replace twice a year.
  3. Regularly check to make sure all sealing surfaces are smooth and undamaged in order to ensure proper sealing.
  4. Our Field Rotor Inspection Program (FRIP) is one more way to maximize functionality and enhance efficiencies.

  1. Familiarize yourself with the rotor’s imbalance tolerance specifications before your run.
  2. Make certain samples and, where applicable, buckets are properly counterbalanced and positioned symmetrically across the rotor spindle.
  3. Verify that all labware has the correct chemical resistances and attributes for the sample type and application you’re running.
  4. Before seating the rotor, make sure the instrument’s chamber and spindle are clean and dry.
  5. Use proper fill volumes, adapters and spacers, and remove moisture from the exterior of all tubes or bottles to prevent them from collapsing.
  6. Always make sure the rotor lid is properly attached and tightened.
  7. Observe required speed reductions for running high-density solutions, plastic adapters, or stainless steel tubes.

  1. Wash rotors and rotor components, including O-rings, immediately if they come into contact with salts or other harmful materials; do not allow these materials to dry on rotor surfaces. Washing and lubricating rotors, rotor components and accessories thoroughly on a regular basis will help extend their useful life.
  2. When washing, use a mild detergent diluted 10:1 with water and a soft brush.
  3. Do not wash rotor components or accessories in a dishwasher or soak them in a detergent solution for prolonged periods.
  4. Do not immerse or spray a swinging-bucket rotor body with water, as water trapped inside can cause corrosion.
  5. Rinse all rotors and rotor components thoroughly with water and air-dry the body or buckets upside down. Do not use acetone to dry rotors.
  6. Clean rotor threads–including those on plugs, buckets, and cavities–with a small amount of concentrated detergent, then rinse and dry thoroughly before lubricating them.
  7. Remove O-rings or gaskets using a non-metal tool to avoid scratches, then wipe them and any contact surfaces clean. Apply a light coat of silicone vacuum grease before reassembly.

  1. Rotors contaminated with radioactive or pathogenic materials must be decontaminated following appropriate laboratory safety guidelines and/or other regulations.
  2. Only use substances that do not damage anodized surfaces– such as isopropyl alcohol–for decontamination.
  3. Do not use strong bases and/or high-pH solutions for decontamination, as they can damage rotors or rotor components.
  4. Use other decontamination products only when necessary and for no longer than the minimum amount of time specified before promptly removing them from all surfaces.

  1. If sterilization or disinfection is necessary, consult your laboratory safety officer regarding proper methods. Otherwise, while sterility or disinfection is not guaranteed by using them, the following methods have been shown to be effective without the risk of damaging the rotor or components.
  2. Leaving O-rings or gaskets in place, remove the lid and bucket caps or rotor plugs and place the rotor or bucket caps upside down in an autoclave at 121°C for up to an hour.
  3. Immerse rotor components for the minimum time specified in Ethanol (70%) or bleach (sodium hypochlorite). Note: Bleach may cause discoloration of anodized surfaces.
