Summary
Purpose of the DR/Check Absorbance Standard Kit (Set of 4)
Answer
The DR/Check Absorbance Standard Kit (Set of 4; Product # 2763900) are secondary gel standards having varying shades of black. These standards are used to verify colorimeter or spectrophotometer response at specific wavelengths. Use the absorbance mode on the instrument when measuring DR/Check Absorbance Standard Kit (Set of 4). Set the instrument to a particular wavelength, zero with the blank standard from this set, and read the absorbance of each of the 3 standards. These standards come with a certificate that shows what the absorbance values should be at certain wavelengths. Measure the absorbance of these standards periodically to check for any significant changes in instrument response.
