Red spirit filled glass thermometers with a yellow back are reliable, non-mercury temperature measurement instruments designed for laboratories that prioritise safety, clarity, and consistent accuracy. Manufactured from durable borosilicate glass that aligns with the material requirements of ASTM E438 Type I, Class A, these thermometers offer strong thermal resistance and excellent chemical durability during routine experimental work. The scale accuracy and graduation quality follow the performance expectations outlined in ISO 1770, ensuring dependable, traceable temperature readings suitable for education, research, and industry.
The red spirit column provides enhanced visibility compared to traditional mercury, while the yellow-back reflector increases contrast for quick and precise measurement. The fine capillary tube supports smooth expansion of the red spirit fluid, reducing reading errors and improving repeatability in laboratory workflows. At 300 mm in length, this thermometer is well suited for water baths, heating blocks, general chemistry experiments, distillation setups, and environmental temperature checks where clear, safe, and accurate temperature monitoring is essential.
LabChoice Australia supplies these red spirit thermometers with careful attention to scale precision, structural quality, and thermal performance in line with international ISO and ASTM guidelines. The borosilicate glass body ensures resilience against temperature cycling, chemical vapours, and day-to-day handling. Supported by the trusted quality standards of LabChoice Australia, this thermometer provides a safe, accurate, and versatile temperature measurement solution for schools, universities, research laboratories, and industrial facilities across Australia.
