New Polishing Cloth Helps keep Optical Faces of Cuvettes Pristine

To enable precision spectrophotometry applications to produce highly accurate results there is a constant requirement to keep the optical faces of a cuvette clean and in a pristine condition at all times. Even the most basic of UV-Visible spectrophotometers are quite capable of measuring differences caused by micro-scratches, surface contamination, etc. not visible to the naked eye. For this reason, the inappropriate use of lens tissues, and/or abrasive or caustic cleaning agents will cause progressive chronic degradation, which again modern instruments are quite capable of compensating for, long after the cuvette should have been discarded.

“Also, in this era of instrumental qualification and control, the day-to-day variation of a modern spectrophotometer pales into insignificance when one considers the effect of a fingerprint on the optical face,” explained John Hammond, Starna’s Technical and Marketing Manager. “

For the above reasons, a similar product to the OPC is routinely used by Starna’s own technicians in all areas of the company’s manufacturing facilities and within the Starna Certified Reference Material Calibration Laboratory”, and is routinely issued as a complimentary product with our Pharmacopoeia compliance kits.
