Beckman.com is conducting maintenance on its shopping cart Friday, July 10th at 9 pm PST thru Sunday, July 12th at 10 pm PST. During this time, orders can still be placed by calling Client Services. We look forward to providing you an improved shopping experience.
We offer several types of sealing tubes designed for use in specific rotor types and applications:
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.
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.
