CHECK STRIPS
Dri-Dye Check Strips
®
offer an easy means of verifying proper calibration and linearity on a routine
basis. If a strip reader can obtain acceptable results with this kit, then the instrument demonstrates
linearity, calibration, filter integrity, repeatability, and lack of stray light. Therefore, proper use
of Dri-Dye Check Strips
®
is recommended to assure long term instrument performance verification.
Dri-Dye Check Strips
®
contain 5 absorbance levels of predispensed chromophore with NIST
traceable absorbance values assigned. Simply add water, wait, mix, and read.
Using predispensed dyes reduces the degree of pipetting precision required to reconstitute the
check set strips. Since the strip reader looks through the sample from top to bottom, volume is
proportional to pathlength and hence to absorbance. If a well is reconstituted with too much water,
the decrease in concentration will be corrected by the increase in pathlength. In fact, the system is
self-correcting for random pipetting errors up to 10%.
The charts and graphs provided in the kit allow instant interpretation of results, because they are
designed to replace the normal calculations with easy to visualize, built-in acceptance ranges.
