Microbiology is a mysterious and novel field, and the research results obtained from this profession have been used in many industries. When conducting microbiological research, due to the need for accurate measurement of cultured bacteria or utensils, moisture analyzers, analysis and semi-micro balances have become important measurement tools. Next we will discuss some of the weighing processes in conventional microbial applications.
If you've ever grown bacteria in a lab for work or school, you may remember the Petri dish. This is the medium in which the bacteria will grow. This medium can be purchased in advance, but it is expensive and specific to certain media, which is why many laboratories make their own medium formulations.
Agar is the key component of medium preparation. Agar is a polysaccharide derived from algae. It can solidify the medium and give it a gel-like texture. It is used because it melts only when heated to boiling temperature but remains molten until it cools to 42 ℃. Why is it useful? Because scientists can completely dissolve the ingredients in agar and make it the medium of their own choice. Another useful feature is that it will not be swallowed or degraded by most bacteria, so we can effectively control the sample.
After the agar is completely dissolved, other ingredients (such as protein EPT, mixed reagent, yeast and broth powder) can be added. They are usually powdery solids and must be soluble in water. Depending on the type of bacteria to be cultivated, there are many kinds of nutritional formulas and nutrients, and you have to use a precision weighing machine to weigh them to follow the formula.For these fine particles or powders, you need to use a small precision digital scale similar to a household electronic scale to make the measured items more accurate and reliable.
Pipettes are used to dispense various liquids during the formulation and compound creation process, so it is critical to ensure that they are dispensed in the correct amount. So in order to be accurate, you need to use an electronic balance to calibrate the pipette.
Microbial biomass is a basic variable used in microbiological research. It allows researchers to determine some subtle factors, such as growth kinetics (the relationship between bacterial growth and substrate concentration), yield factor (the weight of formed bacteria) and metabolic quotient (the amount of carbon dioxide produced), etc. In order to improve the efficiency of the process, precision electronic analytical balance is often used for front and back measurement. At the same time, after the measurement, another digital platform scale is needed to measure to achieve the most accurate data.
From food to cosmetics to drugs, we often use digital measuring scales to measure the weight of samples and compare the weight of different samples, which will help us adjust the size of the sample. For example, the cultivation of some microorganisms requires mixing and crushing many materials, and then measuring them with an electronic scale after processing. The prepared sample needs to be mixed with yeast and other ingredients again, and the final mixture needs to be measured again with a precision scale to get the final result.
It can be seen that weighing equipment plays a very important role in microbiological research. Choosing high-precision electronic scales can effectively improve work efficiency and the accuracy of research results. Our company specializes in the production of high-precision scales, welcome to buy.
