Signal Word: Danger

Hazard statement: H330 H360 H372 H400 H410

Description

For investigating the thermal behaviour (expansion, pressure increase) of gases, for introducing the absolute temperature scale, and for determining absolute zero. Consists of a capillary tube open at one end, in which a variable volume of gas is sealed with a drop of mercury. The open end is treated with gas-permeable frit and silica gel to prevent moisture from forming inside the tube. Includes a glass vessel for the water bath.

Length: 48 cm
Outer diameter of capillary tube: 8 mm
Inner diameter of capillary tube: 2.7 ± 0.2 mm
Divisions: mm scale over the entire length
Connection: 8 mm tubing nipple
Glass vessel:
Length: 44 cm
Diameter: 30 mm
