Quick-Seal Ultracentrifugation Tubes, Beckman Coulter
Tubes Centrifuge Tubes
Quick-seal tubes eliminate most of the steps involved in capping tubes and cut handling time in half.

  • Different types of materials
  • Various configurations
  • Wide selection

The top of the tube is either dome-shaped or bell-shaped with a 3 mm-long inlet through which the tube is filled. The filled tube is heat-sealed using the hand-held sealer (required). The highly reliable seal achieved makes these tubes ideal for sample storage and for working with radioactive or pathogenic samples.

Beckman Coulter quick-seal tubes are designed for use in swinging bucket, vertical tube, near vertical tube, and most fixed angle rotors. The tubes are available in many sizes and in three different designs - dometop, bell-top, and conical bell-top. These are also available in two materials: polypropylene and ultra-Clear. Tubes made of both materials are thin-wall and non-wettable.

These tubes are especially useful for providing secondary biocontainment or for runs requiring cesium chloride gradients. There is no need for caps - the tubes are heat-sealed, resulting in a very reliable seal. However, spacers and/or floating spacers are required to support the tops of the tubes during centrifugation (Please refer to the rotor manual for the list of compatible tubes and spacers).

The g-Max system uses a combination of short bell-top polypropylene quick-seal tubes and floating spacers (also referred to as g-Max spacers). The floating spacers sit on top of the quick- seal tubes; thus, there is no reduction of maximum radius, and therefore, no reduction of g force. The shorter pathlength of the tubes permits you to achieve separations with much faster run times than with full-size tubes.

Caution: Please always check the centrifuge rotor manual for the list of compatible tubes and adapters.
