Digital low-temperature thermostat bath liquid medium selection principles:
When the working temperature in 5-85°C, the liquid medium is generally selected water;
When the working temperature is 85-95°C, the liquid medium can be selected 15% glycerol solution.
When the working temperature is 95°C, the liquid medium is generally used oil, and the selected oil should be higher than the open cup flash point value of the working temperature of more than 50 ° C;
There are pulleys at the bottom of the instrument, and the pulleys can be opened during the moving process, which is convenient for pushing. When the instrument is running, please fix the pulley to avoid the instrument moving during operation, causing damage The instrument has high power, before using, should ensure that the power supply power is greater than the instrument using power, to avoid causing short circuit of the instrument. Percival cryostat adopts three-legged plug with bottom wire device.
In the cryostat tank to add media, should ensure that more than the instrument to use the water level line, to avoid the instrument heater is in a dry burning state. Percival cryostat has a low water level alarm function, when used to join the medium can be heard beeping, such as the instrument is running when the beeping sound that the instrument is in a low water state, should be added in a timely manner sufficient medium. Ensure the safe operation of the instrument digital cryostat in the use of high temperature, please do not look directly at the opening too close, such as the use of the medium is oil, may splash.
With external circulation function of the instrument, low-temperature use is recommended to open the pump cycle, to prevent the water temperature should be too low ice phenomenon, affecting the experiment, the pump cycle is conducive to a more constant water temperature, it is recommended to open.
When the instrument is finished using, switch off the instrument first, and then disconnect the connection cable. Clean the instrument in time to avoid dirt affecting the next experiment. The instrument should be placed in a ventilated location to avoid humidity.
