Polarimeter laboratory tube 02604

glasswith bubble trap

Allows for easy filling Bubble-free for accurate measurements Can be integrated in a range of different applications Meets the ICUMSA recommendations, class A (±0.01%) and the corresponding specifications of the O.I.M.L. and the Australian Standard K 157 regarding construction and precision Glass sample tubes are available for single measurements and come with a standard bubble trap for bubble-free filling. Choose between simple or center filling. The central filling cup allows easy filling and emptying of the tube. Air bubbles escape through the filler opening when moved slightly. Polarimeter tubes of SCHMIDT+HAENSCH are designed for different applications. All tubes meet the ICUMSA recommendations, class A (±0.01%) and the corresponding specifications of the O.I.M.L. and the Australian Standard K 157 regarding construction and precision. In general: Longer measuring tubes are more reliable than short ones. Sample heterogeneity and residues from previous samples have a larger influence on the accuracy of the measurement when applying shorter tubes. Larger sample volumes ensure more stability. An exception is the case of dark samples; a shorter measuring tube might be necessary due to the high absorption of light. Please consider that SCHMIDT+HAENSCH guarantees the precision of polarimeters only if SCHMIDT+HAENSCH measuring tubes are used.
