Benefits
Safe and easy handling
LCK cuvette tests use innovative Dosicaps that are easier to use than powder pillows or liquid reagents. There’s no risk of spillage, no safety risk, or risk of contamination with Dosicaps because the reagents are completely contained within the cuvette cap. The glassware used assures the best precision and the cuvettes have a flat bottom so they can stand on their own.
Packages of LCK cuvette tests are colour-coded for fast and easy parameter and range recognition for the exact test you need. Step-by-step illustrated test methods are printed on the box for quick reference.
Reduce errors
A unique barcode label on each Hach LCK cuvette test is automatically read by the spectrophotometer when used with Hach’s DR6000 UV-VIS spectrophotometer or DR3900 benchtop spectrophotometer to identify the appropriate method and take the measurement. This significantly reduces errors as well as scratched, flawed or dirty glassware becomes non-issue as the instrument averages 10 readings and rejects outliers.
Batch after Batch - Be Right
Truecal with each cuvette includes the calibration data for each individual batch, reducing variation in results. This allows you to meet reporting standards and to perform proficiency testing with higher confidence.
Documented shelf life and COA
The barcode details batch number and expiry date of reagents, which are documented along with the measurement result. An automatic warning is issued if expiry date has passed. Batch specific information (COA) is available on RFID tag on the box, which can be read out with the DR6000 or DR3900 spectrophotometer.
No reagent blank necessary
The high quality of LCK cuvettes, tight reagent production controls, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks - saving you time and money!
