Reaction Vessels & Tubes

Reaction vessels and tubes for centrifugation, PCR and sample storage – in various volumes.

Reaction vessels and centrifuge tubes hold samples while they are mixed, spun, incubated or stored. This subcategory comprises three snap-cap reaction vessels in 0.5, 1.5 and 2.0 ml and two sterile screw-cap centrifuge tubes in 15 and 50 ml. Everything is made of polypropylene.

The reaction vessels come in bags of 500; the centrifuge tubes are racked – 50 per rack for the 15 ml tube and 25 per rack for the 50 ml tube. That lets you buy small volumes in large numbers and larger sample volumes in manageable units.

Typical applications

  • Reactions and aliquots in molecular biology and biochemistry
  • Centrifuging small samples at up to 20,000 × g in the 0.5 ml tube
  • Storing labelled samples in the 2.0 ml tube with writing area
  • Sample preparation and storage of larger volumes in 15 and 50 ml tubes

What to look for when buying

Volume, closure and sterility are what count. Snap-cap reaction vessels open and close with one hand and suit batch work; they are supplied without a sterility claim. Screw-cap centrifuge tubes are sterile, graduated and intended for samples that need to be transported or stored tightly sealed. The 15 ml tube has a conical bottom and is specified as DNase/RNase-free; the 50 ml tube is self-standing and suitable for high g-forces.

Before ordering, check that the tubes fit your rotors and racks. For a hands-on trial, free samples are available for most products.

Frequently asked questions

What maximum g-force is specified?

The 0.5 ml reaction vessel is rated up to 20,000 × g, and the 50 ml tube is described as suitable for high g-forces. The catalogue gives no figure for the other items; ask for the specification if you need it.

Are the reaction vessels sterile?

They carry no sterility claim. In this subcategory only the 15 ml and 50 ml centrifuge tubes are supplied sterile.
