What is the best way to clean the TU5200 Benchtop Laser Turbidimeter sample cells?
Summary
TU5200 sample cell cleaning
Answer
The Sample Vials for TU5200 Benchtop Laser Turbidimeter (Product # LZV946) are best cleaned as follows:

1) Put the exterior and interior surfaces of the sample vial and the cap in 10% hydrochloric acid for 15 minutes.
2) Clean the exterior and interior surfaces of the sample vial and the cap with laboratory cleaning detergent for glass (concentration 0.1%)
3) Fully rinse the sample vial three times with distilled or deionized water. (If the sample vial is used to measure low range turbidity samples or dilution water, rinse with dilution water - not distilled or deionized water)
4) For the best results, clean the sample vial with the optional Manual Vial Wiper for TU5200, TU5300 sc, and TU5400 sc Laser Turbidimeters (Product # LZY903). Then fully rinse the sample vial again.
5) Dry the external surfaces of the sample cell with a soft, no-lint cloth. Do not let the sample vial air dry.
6) For storage, fill the sample vial with distilled or demineralized water. (If the sample vial is used to measure low range turbidity samples or dilution water, fill the sample vial with dilution water)
7) Immediately put the cap on the sample vial to keep the interior of the sample vial wet.
