What Is The Polymerase Chain Reaction?

Polymerase chain reaction (PCR) is a revolutionary method used to analyze and amplify short DNA (or RNA) sequences in a sample with small quantities of RNA or DNA.

What Is ATP Testing?

ATP testing is used for measuring the growing microorganisms by using adenosine triphosphate, or ATP for their detection. ATP is an energy molecule found in living cells, which gives a direct measure of their health and biological concentration. ATP can be quantified by using a luminometer for measuring the light produced through its reaction with [...]

ATP Testing Kits

Hygiene monitoring is critical when it comes to HACCP compliance. It is common for industries like prepared and processed foods, beverage and dairy to enroll in a HACCP program.
