How to choose a vacuum drying oven? Mosquito Killer Lamp,T5 Bl Tube,T5 Bl Lamp,T5 Bl Bulb Changxing leboom lighting product CO.Ltd. , https://www.leboomuvs.com
1 determine the industry in which the user is located
The users of vacuum drying ovens are generally divided into the following industries: 1 biological industry; 2 chemical industry; 3 electronic industry; 4 pharmaceutical industry; 5 scientific research institutions.
2 determine the use temperature of the vacuum drying oven
The temperature control requirements of vacuum drying ovens are generally RT+10~200 °C (RT stands for ambient temperature). In addition, some professional manufacturers will produce needle leveling instruments after understanding the use requirements of a certain industry. The cabinet used in a certain industry, for example, for the bio-industry, produces a cabinet with a temperature control range of 0 to 65 °C in the RT+1 centrifuge. Of course, when we choose a vacuum drying oven, we need to ask ourselves how much we need to control. temperature.
3 determine the liner material of the vacuum drying oven
Vacuum drying ovens are usually divided into cold-rolled sheets and stainless steel "target=_blank> stainless steel according to different materials. Stainless steel "target=_blank> stainless steel is subdivided into 304/316 stainless steel" target=_blank> stainless steel, if we are in chemistry In the field of industry experiments, in order to better resist corrosion, you can choose 316 stainless steel "target=_blank> stainless steel liner.
4 Determine the vacuum degree control method of the ideal conductivity meter
What is the vacuum degree control method? The vacuum degree control method is generally divided into manual control and automatic control. That is, in the process of our experiment, when the object in the box is heated and evaporated to generate water vapor to affect the vacuum degree, the vacuum pump is automatically re-vacuum. Still have to manually vacuum, from the name is not difficult to see, of course, automatic control is more convenient, but the automatic control is more expensive than the manual control of the vacuum drying oven, the so-called value is different here.
5 ask what kind of heating effect you need
Vacuum heating ovens are usually divided into two types, bundled heating and baffle heating. It may be common in domestic laboratories to bundle heat. It is recommended to use baffle heating. The reason is very simple. The heated objects on each layer of the partition can be heated more evenly. We may wish to ask the manufacturer when choosing. What is the heating method.
6 When we choose the most ideal vacuum drying oven,
You can start to determine the working size of the vacuum drying oven. Here are two questions: First question: What is the venue you placed? Whether the vacuum drying oven requires a bench top or a vertical. Second question: How many L is needed for the specific tank volume. At the end of the two questions, the size of the drying box will be fixed.
7 The vacuum drying oven has been selected. Do you still need some accessories to facilitate our work? May ask yourself. The accessories for vacuum drying ovens usually have the following categories:
Program temperature control: Let us no longer bother with the leveling instrument. In an experimental project, the instrument automatically realizes multiple stages of different temperature control and timing. Gas Intake Valve: Allows us to more easily remove air residue from the tank. Liquid Water Filter / Drying Tank: Let us dry the water to protect and extend the life of the vacuum pump. (One constant instrument / Shanghai Yiheng Tips: If the water content of the experiment is large, the two accessories can be used together.) Vacuum pump: This is the most important, the vacuum drying oven must be equipped with a vacuum pump, so the bar coater we When purchasing, you should confirm with the manufacturer whether there is a vacuum pump. If we have it, then it is not necessary. More common are oil pumps and pumps, oil pumps are mostly used. On-site commissioning: Vacuum drying ovens are relatively simple equipment, so generally do not require on-site commissioning, but if there are special needs, it should be realized as an optional value-added service, but the cost is expected to be inevitable. Look at your needs.
