Lab vacuum drying oven is a commonly used teaching instrument, which is widely used in industry, chemical industry, electronics, electric power, colleges and universities, medicine and other fields.
Compared with conventional drying technology, laboratory vacuum drying oven has the following advantages:
1. The vacuum environment lowers the boiling point of the liquid that needs to be removed, so vacuum drying can be easily applied to heat-sensitive substances.
2. For samples that are not easy to dry, such as powder or other granular samples, vacuum drying can shorten the drying time.
3. Various mechanical parts or other porous samples with complex structures are cleaned and then vacuum-dried, leaving no residue after drying.
4. Under vacuum or inert conditions, eliminate the possibility of oxides being heated.
5. Compared with ordinary drying relying on air circulation, powdery samples will not be blown or moved by flowing air.
Points for attention in the use of lab vacuum drying oven:
1. When the lab vacuum drying box does not need to be continuously pumped, the vacuum valve should be closed first, and then the power of the vacuum pump should be turned off, otherwise the vacuum pump oil will be poured into the box.
2. Take out the processed items and tear them up. If the processed items are flammable items, the air must be put in after the temperature is cooled below the ignition point, so as to avoid oxidation reaction and cause combustion.
3. There is no explosion-proof device in the lab vacuum drying oven, and no explosive items should be placed in it for drying.
4. The shell of the lab vacuum drying oven must be effectively grounded to ensure safe use.
5. It is best to cross the filter between the lab vacuum drying oven and the vacuum pump to prevent moisture from entering the vacuum pump.
6. There is no explosion-proof device in the lab vacuum drying box, and it is not allowed to put explosive materials into it for drying.
7. When the lab vacuum drying oven is used, it must be supervised by a special person to ensure the normal operation of the equipment.
8. When the lab vacuum drying oven is not in use for a long time, the items in the working room should be taken out and wiped clean to keep the equipment dry.
9. If there is an abnormal phenomenon in the lab vacuum drying oven, it should be checked and repaired in time. If the fault cannot be accurately judged, please contact the technical department of the purchasing company.
10. When it is not necessary, please do not disassemble the side door at will, so as not to damage the electrical system.
11. The lab vacuum drying oven should be equipped with a special air switch.
12. When the lab vacuum drying oven is used, it must be supervised by a special person to ensure the normal operation of the equipment.
13. When the lab vacuum drying oven is not in use for a long time, the items in the working room should be taken out and wiped clean to keep the equipment dry.
14. The electrical insulation is intact, and the equipment shell must have reliable protective grounding or protective zero connection.
15. Vacuum pump oil should be replaced frequently.
16. When taking out the processed items, if the processed items are flammable items, the air must be put in after the temperature is cooled below the ignition point, so as to avoid oxidation reaction and cause combustion.
Lab vacuum drying oven product features:
1. The heating element is located on the inner partition of the box, and the heating time is shortened by 50% compared with the traditional vacuum drying box.
2. Large-screen LCD display, multiple sets of data displayed on one screen, menu-style operation interface, easy to understand and easy to operate.
3. The aluminum shelf stamped by special process has high temperature non-oxidation and fast heat conduction. Minimize heat loss
4. The cuboid studio maximizes the effective volume, and the microcomputer temperature controller ensures accurate and reliable temperature control.
5. Toughened, double-layer glass door to observe the objects in the working room at a glance, and can fill the interior with inert gas.
6. The closing tightness of the box door can be adjusted by the user, and the integrally formed silicone rubber door seal ensures high vacuum in the box.
7. The working room is made of stainless steel plate, the box shell is made of high-quality cold-rolled steel plate, and the surface is electrostatically sprayed.
8. Storage, heating, testing and drying are carried out in an environment without oxygen or filled with inert gas, which will not cause oxidation.
Frequently asked questions and answers for lab vacuum drying ovens:
1. Can the power supply be disconnected after the lab vacuum drying oven is vacuumed?
Yes, the vacuum pump can be turned off after vacuuming.
If there is a valve between the vacuum pump and the tank, just close the valve and disconnect the power supply.
If the vacuum pump is directly connected to the tank, the vacuum pump stops working after the power is disconnected, and the negative pressure in the tank may suck out the oil in the vacuum pump.
2. Can the vacuum pump be turned off after the lab vacuum drying oven is exhausted?
This problem mainly depends on the characteristics of the dry matter. If there is a lot of solvent, it must be pumped all the time, otherwise the vaporized solvent will condense again when it hits the wall of the box, and some will drip into the dried material, so It is not recommended to turn off the vacuum pump for dry matter with more solvents.
Turning off the vacuum pump is suitable for materials with less solvent, and vacuum storage after removing a small amount of water vapor.
3. Why does the lab vacuum drying oven need to be vacuumed before heating?
If it is heated first, the gas inside the box, especially the water vapor, will react chemically with the dry objects inside the box at high temperature, thus losing the function of the vacuum drying box.
4. How to control the heating temperature in the vacuum state of the laboratory vacuum drying oven?
Lab vacuum drying ovens are designed and manufactured according to the common requirements of different users. Although the control methods, structures, materials, and shapes are different, the heating principles or methods are basically the same. Therefore, when users use it for the first time, it is recommended to do an application test first, that is, to record the surface state of the object to be heated, the number of objects, the placement position, the readings of the instrument and thermometer. After the drying is over, check the drying effect, and determine the optimal number of items and the reading of the instrument (or thermometer). In doing so, you can get twice the result with half the effort.
