Delasco TCA is mixed from absolutely fresh TCA crystals, using proper weight/volume calculations, for standardization of potency. Locally-made TCA is subject to variation.
TCA is often made from old crystals that have lost some of their potency, or by using incorrect formulas, such as weight/weight or other non-standard calculations.
Delasco's translucent, unbreakable and acid-resistant plastic bottles (triple-sealed for shipping) mean less risk of breakage or leaks in transport or in your lab.
Our TCA has no degradable paper liner in the cap.
Our translucent bottles allow you to confirm the clarity, purity and color of the solutions. (TCA is not light-sensitive, so dark bottles just mask the contents). Available in 1 oz (30 ml), 2 oz (60 ml), or 1 pint (16 oz or 480 ml) bottles.
