Sealing Tubes

We offer several types of sealing tubes designed for use in specific rotor types and applications: 

OptiSeal tubes

  • Single-use tubes available in dome-top and bell-top styles.
  • Come with plastic sealing plugs, easily prepared for use without tools or heat.
  • Spacers are used to seal the tubes and to support the tops of the tubes during centrifugation.
  • With the tube plug and spacer (and rotor plug, if required) in place, the g forces during centrifugation ensure a tight, reliable seal.

Quick-Seal tubes 

  • Heat-sealed tubes used in swinging bucket, vertical tube, near vertical tube, and in most fixed-angle rotors.
  • Especially useful for the containment of radioactive or pathogenic samples.
  • The bell-top style simplifies removal of materials that float during centrifugation.
  • Dome-top style tubes hold more volume.
