There are many different weighing methods, and each one offers unique advantages. Choosing the right weighing method will help you optimize your production processes and ensure the quality of your products.
A quality weighing process depends on precision calibration and routine inspection of the equipment. This is particularly important for specialized systems such as process weighing.
Weighing a sample
Weighing is an essential process in the workplace. It quantifies the matter that makes up various objects and helps us use them more efficiently. From making medication to building a bridge, mass and weight are vital components in many applications.
It’s important to keep weighing equipment clean and in good condition so that readings are accurate. This can help you avoid cross-contamination of your samples and erroneous readings. Also, make sure that you always touch the weighing chamber with gloves to avoid hand grease. Lastly, keep the weighing chamber closed to prevent air currents from entering and affecting your reading.
Weighing systems are a great tool for quality control and data collection. They can increase efficiency, decrease deviation from a set standard and make it easy to record and manage results.

Our team of experts will work closely with you to ensure that your weighing systems are accurate, efficient and compliant.
Weighing the sample on a balance
A good weighing process is vital for the pharmaceutical, manufacturing, food, and jewelry industries. It helps reduce waste, ensures quality, and provides traceability. It also helps companies meet regulatory requirements and achieve higher profit margins. The reduction in errors and waste caused by accurate weighing can be seen directly in the bottom line.
First, ensure that the analytical balance is “tared,” or recalibrated to read 0.0000 g. This is done by briefly pressing the control bar. Then add the sample to the container. Be careful not to spill chemicals on the balance, as they may corrode it and change readings.
Also, be sure to use containers that are not too large for the capacity of the balance. Otherwise, air gusts will cause the mass to move up or down. Additionally, condensation and dust accumulation can affect the measurements. Finally, the presence of magnetic materials may interfere with the components of the balance.
Weighing the sample on a scale
In manufacturing, accurate weighing is critical to maintaining quality. It ensures that ingredients are added in the correct order and that the finished product meets quality standards. In addition, it reduces raw material losses and rework, boosting profitability. For sensitive materials, automated weighing systems can also help minimize exposure to humans.
To avoid errors, make sure that the scale is tared before measuring the sample. This can be done by pressing the tare button on the balance or using a calibrated weight to zero the instrument. Then, place the container on the scale and record the weight measurement. Be sure to write the measurement on the label of the container or in a lab notebook to avoid transcription errors.
The weighing process requires careful attention to detail, especially when measuring small masses in humid conditions or with hygroscopic samples. You should also use a face mask and disposable gloves to prevent hair fall or breath from affecting the measurement.
Weighing the sample on a microscope
Having accurate, consistent measurements is essential for businesses that handle large quantities of materials. Accurate weighing reduces waste and raw material losses, and increases profitability. It also helps manufacturers comply with industry standards and regulations. In addition, it reduces employee exposure to hazardous chemicals and improves product consistency.
The simplest way to measure objects under a microscope is by using a graticule and micrometer slide. Place the graticule on the microscope stage and align it with the micrometer scale. Then, count the number of graticule divisions that line up with the micrometer scale and divide them by the number of micrometer scale divisions to get the value in microns (e.g., 48 graticule divisions / 35 micrometer scale divisions = each graticule division is 5.7 um).
Once the microscope is calibrated, you can measure the size of your subjects with the eyepiece reticle scale and convert them to microns to add scale bars to photographs. This method is particularly useful for measuring cellular specimens, such as red blood cells.
