ColorSeed™ is a revolutionary internal certified standard for Cryptosporidium and Giardia testing.

Japanese Water Works Association (JWWA) approved and USEPA approved as a batch control.

ColorSeed™ plus EasyStain™ = best performance for your test method

Each ColorSeed™ tube has a mean between 98 and 102 of inactivated Cryptosporidium oocysts and between mean 98 and 102 inactivated Giardia cysts (with a standard deviation of 2.5 or less) in 1ml of saline solution. All oocyst and cysts are permanently labelled with a red florescent dye.

ColorSeed™ takes quality control of testing Cryptosporidium and Giardia to a revolutionary level by including a control sample in every sample being tested. When added to the test sample, it provides the analyst with an internal quality control parameter against which the performance of every test can be measured.

ColorSeed™ is sealed, sterilised and stable for 4 months from date of manufacture.

To use ColorSeed™, one simply adds the contents of a vial to every sample to be analysed. With ColorSeed™ added, the sample is analysed through the normal procedure. During the final microscopic detection stage of the test, the analyst can identify ColorSeed™ Cryptosporidium and Giardi (oo)cyst (fluorescing red) and intrinsic sample Cryptosporidium and Giardi (oo)cyst (fluorescing green).

The number of ColorSeed™ Cryptosporidium and Giardia (oo)cysts detected provides the percentage recovery achieved in the sample.
