Molecular Diagnostics

Improper sample storage can jeopardize months of research work and quickly send you back to square one. From leaky tubes to poorly configured cold storage organization, one seemingly small mistake has the potential to not only drain resources, but also produce inaccurate findings.



Also available within our molecular diagnostics range are 2D storage tubes and pipet tips for liquid handling.

FAQ

Do all of your storage tubes meet ASTM standards?

Most manufacturers’ tubes will not be pressure tested for ability to withstand leaks at 95 kPA (14psi). They may work, but have not been tested and verified in these conditions. Corning's products with plug seal caps are an example of one that is verified to ASTM standards.

How should my storage requirements vary if I’m saving samples for longer-term research rather than rapid patient testing?

Most transport tubes are not suitable for testing at <-70°C for long periods due to their thinner tube walls and butyl seal, if any seal at all. A true cryovial - with its thicker walls and silicon or TPE seals - will withstand the potentially deleterious effects of cold storage.
