Borosilicate-glass polarimeter (optical rotation) sample tubes with high light transmittance. They come in funnel, bubble, jacketed (thermostatic) and micro styles, in standard (STD) and precision (PREC) grades and 50 / 100 / 200 mm lengths. Spare rubber washers and optical glass windows are also available. They fit most polarimeters, including WXG-4, WXG-5, WZZ-1, WZZ-2A/2B, WZZ-3, WZZ-1S/1SS and WZZ-2S/2SS.
Key Features
Heat- and chemical-resistant borosilicate glass with excellent light transmittance
Funnel type: wide inlet for easy filling with less spillage
Bubble type: a middle bubble trap removes air bubbles for stable readings.
Jacketed type: water jacket for stable constant-temperature measurement, e.g. sugar and pharmaceutical testing
Sealed caps with matched rubber gaskets: leak-proof and easy to disassemble
Resistant to acids, alkalis and organic solvents. Reusable after cleaning.
