What is the Role of Weighing Equipment in Microbiology?

Microbiology is one of the branches of biology. At the molecular, cellular or population level, it studies the basic laws of life activities such as morphological structure, growth and reproduction, physiological metabolism, genetic variation, ecological distribution and taxonomic evolution of various micro-organisms. These micro-organisms include bacteria, actinomycetes, fungi, viruses, Rickettsia, mycoplasma, chlamydia, spirochete protozoa and unicellular algae. Microbiology applies this basic law to the fields of industrial fermentation, medical health and bioengineering.

What Commonly Used Instruments are Needed in Microbiological Laboratories?

Aseptic Room

Aseptic room is the core part of the laboratory, which mainly provides protection for samples and ensures the accuracy of experimental results and the safety of personnel.


Super Clean Workbench

Microbial culture is carried out in a specific medium for aseptic culture, so aseptic culture must require a super clean workbench to provide a sterile working environment. The main purpose of super clean workbench is to inoculate microorganisms and aseptic operations during treatment.


High-Pressure Steam Sterilization Pot

The autoclave is a sealed, double-layer metal pot that can withstand certain pressure. Generally, before aseptic operation, the operating utensils and culture medium should be sterilized in the autoclave before use.



The incubator is mainly used for the cultivation of microorganisms in the laboratory and provides a suitable environment for the growth of microorganisms.


Laboratory Balance

The balance is a kind of equipment for accurately weighing all kinds of reagents and drugs. Laboratory analytical balance and electronic top pan balance are commonly used in laboratories.



The micro-organisms are so small that their individual morphology and cell structure can be observed clearly with the help of a microscope. Therefore, in the research of Microbiology, microscopes have become an indispensable tool.


Colony Counter

The colony counter can help the operator count the number of colonies. The number of colonies can be accurately obtained by magnifying, photographing and counting. Some high-performance colony counters can also be directly connected to the computer to complete the automatic counting operation, which is convenient and fast.



Spectrophotometer can be used to determine the concentration of microbial suspension in microbial tests, which can correctly select the appropriate culture time.



Centrifuges are used to collect microorganisms and other sediments. Centrifuges are divided into freezing centrifuges and normal temperature centrifuges.


liquid Nitrogen Tank

Liquid nitrogen tank contains liquid nitrogen, which can be used for long-term preservation of various strains in the microbial laboratory.

Classification and Characteristics of Balance

Balance is the oldest measuring instrument used to weigh the weight of objects. It has a history of more than 4000 years, and has experienced a development process from simple to complex, from low accuracy to high accuracy. It is the continuous development of the balance that the precision of balance and accuracy of weighing balance are constantly improving.


According to the structural principle of the balance, it can be divided into four categories: torsion balance, hydrostatic balance, lever balance and electronic balance. Among them, lever balance and electronic balance are the most common balances.


As the most basic equipment of weighing in the microbial testing laboratory, the appropriate balance should be selected according to the different weighing objects and weighing accuracy requirements, combined with the situation of the laboratory. In microbial research experiments, we mostly use laboratory fine balance or laboratory precision balance.、


The balance which balances the mass of the object by electromagnetic force is called electronic balance. Compared with mechanical balance, lab electronic balance has the characteristics of accurate weighing, fast and clear display. In addition, electronic precision balance has the functions of calibration, digital display, automatic peeling, automatic data output and automatic fault inquiry.



The study of microorganisms requires us to be careful and careful, so a set of precise experimental instruments is essential. Lab precision electronic digital balance and lab precision electronic gold balance can bring you accurate results.
