Its main products include but are not limited to chemical reagents, standard products, gas chromatography-related consumables, liquid chromatography-related consumables, sample preparation products, laboratory general consumables, small instruments, etc. Today, we will mainly talk about the HAWACH vacuum filtration apparatus: vacuum filtration.

HAWACH vacuum filtration apparatus: vacuum filtration

vacuum filtration is widely used in the filtration of various liquids in the laboratory, including the detection of various microorganisms in food, medicine, beverages, and drinking water, determination of suspended solids in water, and sample preparation or solvent purification for trace analysis of HPLC, GC, AA, etc. This combination is a unique vacuum filtration design, which is composed of a filter funnel combined with a fast-draining waste liquid bottle and a magnetic fixed seat pumping, which can conveniently and quickly drain the waste liquid, and it is not easy to fall down.

Solvent filter

A solvent filter is a frequently used device in a chemical laboratory. In chromatographic analysis, it plays a vital role in removing impurities that affect the life of the column and the accuracy of the system detection. The degassing effect of the liquid during the filtration process is also very obvious. The device is equipped with filter membranes for different purposes and is widely used in gravimetric analysis, microanalysis, colloidal separation, and sterility testing.

Vacuum Filtration Procedure:

  1. Assembling the Apparatus:
    • Set up the filter flask, and filter funnel, and connect the rubber or silicone tubing to the vacuum source.
  2. Preparing the Filter Paper or Membrane:
    • Place the appropriate filter paper or membrane in the filter funnel, ensuring it covers the entire surface.
  3. Adding the Sample:
    • Pour the liquid sample containing solid particles into the filter funnel.
  4. Initiating Vacuum:
    • Turn on the vacuum source, creating a pressure difference that forces the liquid through the filter paper or membrane, leaving solid particles behind.
  5. Collecting Filtrate:
    • The liquid, now free from solid particles, is collected in the filter flask.
  6. Completion of Filtration:
    • Once the filtration is complete, turn off the vacuum source and carefully disassemble the apparatus.
