Price of laboratory heating plate: laboratory heating plate can meet the needs of different experiments
Laboratory electric heating plate is a dedicated to analyzing all kinds of sample pretreatment for heating thermostatic device, using a simple keyboard keys, the controller design, LCD screen display, safety lock, hour meter function, as well as the high temperature alarm prompt, convenient to use, suitable for most of the vessel, glass, ceramic, metal, all can't, operation mode diversification, cooperate with the needs of different experiments.
Laboratory heating plates convert electrical energy into heat energy to heat objects. Is a form of electricity utilization. The temperature distribution of the heated object can be maintained as needed. Electric heating can generate heat directly in the heated object, so the thermal efficiency is high and the heating rate is fast. According to the technical requirements of heating, uniform heating or partial heating (including surface heating) can be achieved. It is easy to achieve vacuum heating and control atmosphere heating. In the process of electric heating, there is little waste gas, residue and smoke, which can keep the heated object clean and do not pollute the environment. Therefore, electric heating is widely used in the fields of production, scientific research and experiment. Electric heating is used especially in the manufacture of single crystal and transistor, mechanical parts and surface quenching, smelting of ferroalloy and manufacture of artificial graphite.
The use of the electric heating plate in the laboratory should follow the corresponding specifications, among which:
1. Fix the pole in the screw hole above the back of the agitator, adjust the height of the cross clip, fix the reaction bottle with the clip, insert the power supply ~ 220V, and open the switch.
Set according to add 2, temperature setting: "bring" or set minus "▼" key not to put, will quickly setting out the required heating temperature, such as: 100 ℃, green light said heating, green light goes out to stop, microcomputer based on the determined by the temperature difference size of set temperature and the current temperature and quantity of heat, ensure no WenChong warming in place at a time, and keep the set value and display values for heat balance of the + / - 1 ℃ temperature differences, make the heating process easily.
3. Self-setting function: when different heating sections or heating power and the amount of solution are irregular, the heating time zui is short, the heating temperature zui is small, and the balance zui is good. However, after changing the heating medium or heating conditions, the self-setting should be reset.
4, start self-setting: often press the shift key "?" 5 seconds, the setting window digital flicker enters the self-setting state, after three times of warm flush, the digital flicker stops, indicating that the self-setting is over and can be used, but the self-setting needs to be used at the initial heating, and the self-setting in the middle is not accurate.
5. There is a rubber plug below the instrument to protect the external thermocouple socket from corrosion and rust and to conduct the inner wire. If the plug is pulled out, the inner probe will be disconnected and the machine will stop working. If the external thermocouple should be removed and saved, the external thermocouple plug into the socket and lock the nut, and then put the stainless steel probe into the solution for temperature control heating.
