Transformation Tube, 15 mL
Product Code : EL-BLS-10954
Last updated: 6 October 2026
Quick answer: A sterile 15 mL polypropylene tube with thermal properties suited to yielding a high number of competent cells for transformation, free of surfactants and detergents that inhibit bacterial transformation. Size 17 x 100 mm with a snap cap. Pack of 25.
Bacterial transformation is unusually sensitive to the vessel. Heat shock depends on how fast the tube wall conducts, so wall thickness and material change the yield; and any surfactant residue left from moulding will inhibit the transformation outright. This listing addresses both: the tube is stated to have the appropriate thermal properties for yielding a high number of competent cells, and to be free of surfactants and detergents that inhibit bacterial transformations.
That second point is the reason to buy a tube specified for transformation rather than a general 15 mL tube. A standard centrifuge tube may be chemically clean for most purposes and still carry enough mould release to spoil a transformation, which is a failure students cannot diagnose.
The published specification is a 15 mL capacity, 17 x 100 mm, polypropylene with a polypropylene snap cap, sterile, chemical resistant, in packs of 25. Ask for the sterilisation method and the transformation efficiency the tube has been tested at, if you need a figure to compare against.
