PM-160 PVG SPECIFIC GRAVITY BOTTLES WITH GROUND IN THERMOMETER 0 TO 50 C

A density bottle with a thermometer (also known as a pycnometer or specific gravity bottle) is a precision glass instrument used to accurately measure the density or specific gravity of liquids.

An essential instrument for chemistry, biology, and industrial laboratory applications.

Manufactured from high-purity, low-expansion borosilicate glass (such as 3.3 borosilicate) to resist thermal stress and chemical corrosion
Specific gravity bottles are calibrated to ensure accuracy in density measurements.

Usually features a built-in standard-joint thermometer (commonly scaled from +10°C to +50°C with 0.5°C increments) to monitor sample temperature in real time for temperature-corrected.
The specific gravity bottle is sealed with a ground glass stopper or cap that fits tightly into the neck of the bottle.

Features a narrow neck and tight-fitting stopper for easy filling, secure handling, and reproducible measurements.
