A crucial parameter for all laboratory applications is temperature. It can influence the phase conditions or consistencies of several analytes, and change the reaction dynamics of substances under examination. Incident heat must be alleviated by ensuring consistent facility conditions wherever heat-sensitive samples are stored or handled.
The temperature of refrigerators and clean rooms are usually calibrated for application-specific temperatures, and meticulous handling procedures are used to reduce the risk of sample spoiling because of external temperatures. Heating elements and heat-treatment sample chambers meanwhile are checked and modified using sensitive thermocouples.
Thermocouples are sensors having two metal wires welded at a temperature-sensitive junction. They are combined into thermal processing equipment and laboratory heaters to attain internal temperatures as an electrical value. This value is transferred to a dedicated temperature controller, where scientists can observe and alter the sample parameters as necessary.
These probes are fully modifiable, with varying lengths, diameters, and metallic compositions to meet diverse experiment requirements. Glas-Col supplies a wide range of base metal thermocouples for laboratory applications, with typical lead lengths of up to 72″ and a mini-plug for easy integration with Glas-Col’s temperature controllers.
Glas-Col’s product range consists of:
- Type J thermocouples — formed of an iron–constantan junction having an exceptional sensitivity of up to 50 µV/°C across a suggested temperature range of 0 °C–750 °C (0 °F–1382 °F)
- Type K thermocouples — general-purpose temperature probes having chromel–alumel wire legs. They are designed with the recommended temperature range of −50 °C to 1000 °C (−58 °F to 1832 °F).
- Type T thermocouples — comprise of copper–constantan wires having a temperature range of approximately 0 °C–370 °C (0 °F–698 °F)
These thermocouples are available in different specifications, with optional synthetic fluoropolymer coatings of polytetrafluoroethylene (PTFE). These coatings with chemical-resistance feature safeguard the thermocouple’s insulating sheath to lower the risk of mechanical failure because of corrosion.
Temperature Monitoring with Thermocouples
Thermocouples obtain the electrical signal relating to a sample chamber’s temperature conditions, but temperature monitors and digital thermometers convert that signal into an understandable value for research applications. It offers the base signal for process control and monitoring in temperature crucial research applications. Glas-Col’s precision heating controls are available with diverse thermocouple specifications, each of which can acquire temperature data with an accuracy of within 1.0 °C.
