Laboratory Vacuum Pump is an adjustable tool that can serve a wide variety of research needs for researchers and scientists. Vacuum pumps are modelled to lessen the pressure of the system by reducing the boiling point of a solution. Once the boiling point is reduced, the solution evaporates at a low temperature which in turn decreases the sample degradation. Vacuum pumps comprise Rotary Vane Pumps, Diaphragm Pumps, Combination Pumps, and Scroll Pumps provide the combination of vacuum pump solutions.
Therefore, some common types of lab vacuum pumps are oil-free vacuum pumps, water aspirators, Rotary Vane Vacuum Pumps, etc. Further, the type of technology used in lab vacuum pumps is Rotary Vane, Rotary Screw, Rotary Claw, Side Channel Blower, Rotary Lobe, Radial Fans, Liquid Ring, etc. Furthermore, lab vacuum pumps are used in various commercials and industries. Also, the applications to remove the molecules of the gas and air. Below are some common Uses of Laboratory Vacuum:
● Next, it is also used for providing suction to move the aspiration or filtration of the suspended samples or the liquid.
● The laboratory vacuum pump is also used in improving the instrument-detection sensitiveness by evaluating the molecules of the air.
● Helps in controlling or inducing the evaporation of the solution by lessening the vapour pressure as in concentrators, rotary evaporators, ovens, gel dryers, etc.
Types of Vaccum Pumps used in Laboratories:
● Diaphragm Vacuum Pumps: Diaphragm Vacuum Pumps need oil to operate. This type of laboratory appliance is suitable for certain functions like liquid degassing, filtration, backing pumps, etc. It utilizes the rotating piston, which shifts diaphragms to do the traction.
● Rotary Vane Vaccum Pumps: Rotary Vane Vacuum Pumps are the most commonly used pumps. At the same time, they are also considered cheap. The processes like reduction of the dry gas or continuous suction are performed. Further, the rotary vane vacuum pumps can be used in the atmosphere by the researchers. Therefore, special air filters help in removing the air filters.
● Scroll Vacuum Pumps: Scroll Vacuum Pump is a dry pump and needs no oil to operate. This type of vacuum pump needs less maintenance and operates with no or less noise.
● Combination Vacuum Pumps: Combination Vacuum Pumps is a combination of Rotary Vane Vacuum Pump and Diaphragm Vacuum Pump in one. Hence, the combination of both the pumps and their usage relates to significant duty activities utilizing harsh chemicals.
Factors to be Considered to Choose the Perfect Laboratory Vaccum Pump:
● Type of Pump: The most common types of lab vacuum pumps are oil-free vacuum pumps that use dry lubricant and not oil. Next, the Rotary Vane Vacuum Pumps are the kind of oil-sealed that is used for several applications in the lab. Further, Water Aspirants are easy to operate and less expensive. It demands continuous water flow.
● Model of Pump: You can select either of the 2 models of the pump: Max Vacuum and Max flow rate. The Max vacuum is the lowest level of pressure that a lab vacuum can grab. Next, the Max flow rate, also known as pumping speed is the elevated rate that the lab vacuum pump can evacuate vapours.
● Horsepower (hp): Horsepower is the ratio of mechanical energy used by the vacuum pump. Hence, the Rotary Vane Vacuum pumps drag a strong vacuum and utilize 1/2 hp- 1/3 hp.
● Motor Speed (rpm): RPM stands for "Revolutions per minute". Therefore, this mostly varies between 1275 rpm- 1750 rpm.
● Noise level (dB): The amount of noise the vacuum pump will produce while operating, determines the noise level. At first, the oil-free pumps range from 50 dB-68 dB and are generally quiet. Simultaneously, the water aspirant has no motor and is quiet.
● Net Weight (Kg): The weight of the laboratory Vaccum pump unit ranges from 4 kg-14 kg.
● Hose barb(mm): Hose barb is the inner diameter of the fittings of the hose barb. Thus, hose barb models range from 8 mm-10 mm.
Benefits of Laboratory Vacuum Pump:
● The lab vacuum pumps are used for moving the dangerous material with safety. Hence, this protects the environment from toxic wastage.
● The lab vacuum pumps are also used to securely friction & drag the trash of mine camp.
● The laboratory vacuum pumps are used in power jets, dipping tanks, and rear doors which are suitable to be used in a wide range of applications.
● At the same time, these vacuum pumps can avoid spills and control the odour to make stable & manageable transport materials of the bio-solids.
● These pumps are also beneficial in removing the wastage quickly from the blocked drains. Further, this accomplishes the tasks accurately and is less time-consuming.
Selecting the Vacuum Pump for laboratory use:
Application is the most important factor to be considered while selecting the vacuum pump. For the basic application of the suction, the most suitable option is the dry pump for the filtration process and aspiration process. On the other hand, the pumping speed of the vacuum pump should also be considered.
