Choosing the Right Vacuum Aspirator: A Complete Guide


Vacuum Aspirator 

Sizes and capacities distinguish Vacuum Aspirators to meet the needs and diverse range of applications and experiments researchers perform in research facilities and laboratories. The length of any vacuum aspirator is usually determined by the fluid flow rate, which quantifies the movement of liquid and the level of suction required for the experiment. Small aspirators are generally designed for everyday and regular laboratory tasks; on the other hand, medium and large-size Vacuum aspirators are more utilized for industrial usage and more complex and extensive operations. As a researcher, the choice among different sizes of vacuum aspirators exclusively depends on the particular requirement, nature, and processes of the facility and working floor. Hence, an individual must select an aspirator with suitable features and specifications for specific tasks and procedures. 

How to Choose the Right Vacuum Aspirator 

I-Spirator Mini:

I-Spirator Mini is the smallest Aspirator designed and constructed at IMRALI Inventions. The device has a volume of 500 ml and can be utilized in any Duran bottle designed especially for Laboratory methods, including cell culture preparation. The common applications of I-Spirator Mini are mentioned below: 

  • This Mini model can regularly be utilized in processes including suction filtration, which is a method that includes the dissociation of a solid phase from a liquid phase by a procedure performed under vacuum pressure.
  • Mini aspirators can also be used in processes performed for the concentration of fluids, which helps the examiner extract the excess solvent from the samples.
  • The smallest Aspirator also facilitates the researcher for the fluid transfers between flasks or containers, furthermore, the Aspirator also allows the movement of fluids without the requirement of manual fluid pouring, reducing the physical stress on the researcher.
  • The mini device can be used to construct a product or multiple compounds by processes involving simple compounds. The device is perfectly built for facilities and labs that facilitate organic synthesis.
  • DNA structuring and cell culture media preparation usually involve processes that require the utilization of small instrumentals. Thus, the I-Spirator Mini can easily be used for tissue culture.
  • Lastly, the device can also be employed to collect liquid waste in separate containers.

I-Spirator Midi:

I-Spirator Midi at IMRALI INVENTIONS is built for handling larger volumes of fluids. This device can be used with one-, two— and three-litre Nalgene Bottles, giving more flexibility to the researcher performing various aspiration processes. The device has more capacity than our Mini model but is ideal for situations that incorporate substantial vacuum. The uses of the device are as follows:

  • This midi model is ideal for handling greater fluid volumes in filtration processes. Midi, unlike mini, also includes the processes of dissociations of liquids on a larger scale.
  • The instrument can also be deployed in distillation processes, which include separating the substances on the boiling point levels; hence, the purification of liquids can easily be performed with i-Spirator Midi.
  • This Aspirator is the perfect choice for drying processes and heat treatments; thus, the device is essential for the procedures performed under reduced pressure.
  • Like mini, Midi is also useful for large-scale chemical substance synthesis. So, for synthesis requiring a large reaction container, Midi is the ideal choice for functions where removing an element or substance is crucial.
  • Ideally for industrial usage, this medium Aspirator is used in numerous processes, such as removing impurities from chemicals, degasification, and gas from liquids.

I-Spirator Maxi:

I-Spirator Maxi is built to have a storage capacity of 5 litres. This Aspirator is the largest among three aspirators, designed for larger volumes of fluids, providing a significant vacuum pressure, and, hence, is ideal for numerous industrial and research facility applications. The instrument has more capacity than our Mini and Midi models. Below are the uses of our largest Aspirator, Maxi:

  • Like Mini and Midi, Maxi can be used in industrial settings for procedures, for instance, distillations, degassing, and suction filtration.
  • This device is ideal for large-scale processes performed in chemical and pharmaceutical manufacturing. This large Aspirator with substantial capacity facilitates various methods, which include substance concentration and chemical distillation, on a mass scale.
  • In an industrial setting, with Maxi’s assistance, processes are tested on a large scale, enabling researchers to test fluids on a greater level.
  • Apart from the chemical industry, Maxi can be used in bioprocessing. The instrument is utilized in handling biological samples on a larger scale than mini and Midi.
  • The device can filter large liquid quantities with a waste storage capacity of 5 litres. Moreover, researchers can also use maxi in industries such as metallurgy and electronics.


The vacuum aspirator is intended to use in the laboratory for sucking liquid from the laboratory vessels like a beaker, flasks, Petri dishes, etc. There are three types of vacuum aspirators used in the laboratory i.g. I-Spirator Mini, I-Spirator Maxi, and I-Spirator Midi. Depending on the volume of the liquid required for sucking, the I-Spirator is selected. The I-Spirator Maxi has a storage capacity of 5 Liters; similarly, the I-Spirator Mini has a capacity of 500 ml, and the Midi has a 2-3 litre volume of liquid capacity.
