Pocket Glass Thermometer, 155 mm, Blue LO-tox, -10°C to +110°C, Blue Case

Description

The Pocket Glass Thermometer, 155 mm, Blue LO-tox, -10°C to +110°C, also known as a pocket laboratory thermometer, LO-tox glass thermometer or portable spirit thermometer, is designed for measuring temperatures during routine laboratory testing, scientific experiments and educational activities. Manufactured by Brannan UK, this portable thermometer combines a traditional liquid-in-glass measuring system with a protective blue plastic case. Its compact pen-style design allows convenient temperature monitoring without batteries or electronic equipment. The thermometer measures temperatures from -10°C to +110°C, making it suitable for general laboratory measurements, heating and cooling investigations, liquid temperature checks and educational science experiments.

Its 1.0°C scale divisions allow users to observe and record temperatures directly in Celsius. These graduation intervals indicate the spacing between scale markings and should not be confused with the instrument’s measurement accuracy. The blue LO-tox filling is a specially developed organic liquid designed by Brannan as an alternative to mercury. It provides a visible measuring column while reducing the hazards associated with conventional mercury-filled thermometers. As the surrounding temperature changes, the LO-tox liquid expands or contracts within the narrow glass capillary. The position of the blue column against the graduated scale indicates the temperature being measured.

The compact 155 mm design makes the thermometer convenient for portable temperature measurements. Its slim construction allows laboratory personnel and students to carry the instrument between workstations and experimental areas. A blue plastic protective case helps protect the fragile glass body during storage and transportation. The case features a pen-style design with an integrated clip for attachment to laboratory coats or pockets. During measurement, the glass thermometer remains secured in the case cap, allowing the protective body to be removed while retaining the thermometer in its holder. This arrangement provides convenient access to the measuring section.

The thermometer is calibrated for total immersion, meaning the liquid column should be immersed to approximately the measured temperature level, according to the manufacturer’s instructions. Correct immersion is important for obtaining reliable readings. The instrument is suitable for chemistry experiments, water temperature investigations, cooling demonstrations and routine laboratory temperature monitoring where its operating range and measurement characteristics meet the requirements of the procedure. For temperature measurements, remove the protective case body, position the thermometer correctly and allow sufficient time for the liquid column to stabilise. Read the Celsius scale at eye level and avoid contact with container surfaces that may influence the result.

Safety Precautions: Handle the glass thermometer carefully to prevent breakage. Avoid direct flames, sudden temperature changes and measurements outside the specified range. Follow laboratory procedures when handling broken glass or spilled LO-tox filling. Each unit is supplied as one Brannan Blue LO-tox Pocket Thermometer with a protective blue plastic case and pen-style clip. Calibration certification is not confirmed as included.
