Invest in the safety of your lab

With total-system design in mind from the start, Beckman Coulter Life Sciences designs ultracentrifuge labware to complement the Optima Series ultracentrifuges, optimizing performance, ease of use, and safety.

Centrifugation Total System Design Logo
  • Beckman designs the rotors in a way that the tube/bottle is supported correctly to minimize high stress areas that may cause premature failure
  • Compare theoretical models vs actual results
    • During the rotor design phase, sophisticated simulation software allows engineers to remove problem areas
    • Beckman Coulter centrifuge products go through Maximum Credible Accident testing to ensure instrument containment safety
    • The results are part of the certification process for the CSA and CE marks for Optima Series ultracentrifuges.

Therefore, using our consumables with our rotors is necessary.

Sealing Tubes

We offer 2 different types of sealing tubes that are compatible with ultracentrifuge rotors. Sealable tubes allow for the 1st level of biocontainment for tube transfers to rotors.

OptiSeal Tubes

Employ patented technology to provide a fast, reliable seal every time. Seal with a finger-touch and without tools, heat, or closure verification. Wide necks offer effortless filling and fraction collection.

OptiSeal Tubes Principle

  • Material Offering: Thinwall PP
  • Volume Range: 3.3 ml — 36.3 ml
  • Compatible with 20 Ultra Rotors
  • Can be sliced or punctured
  • Wider tube neck allows for easier buffer and sample exchange
  • Uses a push-in Noryl plug with O-ring to seal tubes
  • Ability to be unplugged for sample recovery
  • Tube rack provides a convenient means of holding tubes during loading and unloading, which also keeps fingers clear during syringe extraction
  • Requires spacer above tube during centrifugation

4.9 362185 Polypropylene 13 x 51 VTi 90, VTi 65.2, NVT 90, NVT 65.2

Quick-Seal Tubes

Provide secondary BioSafe* containment. Seal with a simple, hand-held sealing tool without plugs or O-rings.

  • Material Offerings: Thinwall PP and Ultra-Clear
  • Volume Range: 1 mL – 100 mL
  • Styles: Round Bottom and konical Bottom
  • Compatible with 36 Ultra Rotors
  • Can be sliced or punctured
  • Handheld heat sealer and accessories to seal the tubes
  • Requires spacers above tube during centrifugation
  • g-Max System – allow flexibility of volumes within the same ultracentrifuge rotors while maximizing efficiency
g-Max System Principle

Advantages of g-Max spacers:

  • No reduction in rotor g-force
  • Reduced run time (shorter pathlength)
