Page 26: Important Operating Notes
Important operating notes 1. The device is only suitable for aqueous solutions. 2. Only use sample tubes which were obtained from KNAUER or recom- mended by KNAUER. Sample tubes should not be reused. 3. To ensure a fixed sample volume, always introduce the solutions with a clean and dry pipette tip into the sample tube. - Page 27 Calibration solu- tions should be used not longer than 30 – 60 min after the tubes were opened. We recommend using KNAUER calibration solutions which are mentioned in chapter „13. Repeat orders“ on page 42.
