TIP1. Three advantages of choosing a PTFE coated vacuum pump
There are many types of vacuum pumps in the laboratory, whether it is oil-free vacuum pumps , oil-type vacuum pumps , corrosion-resistant vacuum pumps , etc., the vacuum pumps used according to the type of experiment are different, and the price is very different depending on the severity of use. . How to find the most suitable vacuum pump has always been a matter of learning. Let me introduce to you a new PTFE coated vacuum pump from Loco. This vacuum pump has the following three characteristics: |
1. The strongest CP value vacuum vacuum pump resistant to organic and corrosive gases
In the course of the experiment, organic solvents or acid-alkaline gases are often encountered, whether it is solvent purification of HPLC mobile phase , bleaching water commonly used for sterilization and sterilization , acetone which is the most commonly used organic solvent , etc., such as a general vacuum vacuum pump. Vacuum filtration of such organic solvents and corrosive gases can easily damage vacuum vacuum pumps. However, the price of a corrosion-resistant vacuum pump is not cheap, so the PTFE coated vacuum pump is a good choice for price considerations. As the name implies, the PTFE coated vacuum pump is coated with PTFE (as shown in the figure below) and the gas is also made of stainless steel #316. In addition to being resistant to most solvents, it can also effectively resist corrosive gases and allow vacuum pumps. One more layer of protection. Such a design greatly reduces the material cost, but has a certain anti-organic and corrosive gas effect, and is a high-quality vacuum pump design with a very high CP value.
2. Not afraid of the experimental process with a lot of water vapor
The filtration experiment process will inevitably produce water vapor, especially the experiments related to the aqueous solution. Water vapor is one of the main causes of rust damage to vacuum pumps. Moreover, after the water vapor condenses, a large amount of white scale is generated, which easily blocks the cavity of the vacuum pump and causes clogging of the pores, thereby reducing the flow rate of the vacuum pump and even affecting the operation of the vacuum pump. The PTFE material used in the PTFE coated vacuum pump has a very low coefficient of friction, so that dust and scale do not adhere to the vacuum pump, and its corrosion resistance is also resistant to the rust caused by a large amount of moisture. Keep the vacuum pump in good working condition.
PTFE coating does not adsorb liquids and layers like GoreTex
Inadvertently pumping in water, don't worry about it. Presumably, most of the experimenters who use vacuum vacuum pumps have experienced inadvertently pumping in water and causing damage to the vacuum pump. The diaphragm structure of the PTFE coated vacuum pump allows the cylinder and motor structure to be completely closed. Therefore, even if you accidentally pump in water, you don't have to worry about it. You can avoid the vacuum pump damage by following the simple four steps below.
1). Turn off the vacuum pump power supply quickly.
2). Remove the vacuum line
3). Tilting the vacuum pump to allow the aqueous solution drawn into the cylinder to flow out
4). Turn on the vacuum pump and evacuate the atmosphere for 1 minute to clean the vacuum pump.
The vacuum pump can continue to use the residual water in the cylinder.
3. PTFE coated vacuum pump can not resist the corrosion resistance of strong acid and alkali grade, like the corrosion-resistant vacuum pump made entirely of PTFE material, but the wide range of usability and price of the people is indeed one of the necessary equipment in the laboratory. Oh!
