A laboratory scale is an indispensable tool in both research and production environments.
The main function of a laboratory scale is to ensure the accuracy and reproducibility of measurement results. Inaccurate measurement results can lead to quality problems or even safety hazards in many industries. A particular challenge, especially in the pharmaceutical and food industries, where even minor errors can have a critical impact on the result.
The choice of the correct laboratory scale depends on the needs of the industry, the user and the environment in which it will be used. It’s also vital to consider the characteristics of the scale and the importance of calibration and maintenance. This article explains how to choose a laboratory scale to ensure your measurements remain accurate and reliable.
Choosing the correct laboratory scale starts with your needs
Different types of scales serve various purposes. Key factors in selection include sample size, accuracy requirements, and the operating environment. For instance, a micro-scale is designed to precisely analyze small samples, while an analytical scale is ideal for more detailed work, such as in the pharmaceutical industry. On the other hand, a precision scale is suitable for weighing larger samples and is commonly used in industrial and educational settings.
Selecting a scale tailored to your specific needs ensures reliable and accurate measurement results.
Microscale – For ultra-precise measurements
A microscale is designed to weigh microscopic and delicate samples. It’s an indispensable tool for applications requiring microgram-level accuracy, such as chemical analysis or medical research.
Analytical scale – For high-precision weighing
An analytical scale is specifically designed for laboratory use where high accuracy is essential but with a slightly broader range than microscales. Its weighing capacity typically ranges from a few dozen to several hundred grams. The scales’ high precision makes it the preferred choice for chemical laboratories, pharmaceutical production, and food quality control.
Precision scale – For accurate weighing of large samples
A precision scale is a versatile tool, especially suited for weighing large or medium-sized samples. It can handle weights from several grams to kilograms. This type of scale is often used in industrial environments, education, and applications where extreme accuracy is not critical, but reliable results are still required.

| Accuracy | Extremely high | High | Good |
| Measurement range | Small | Medium | Large |
| Applications | Small samples, research | Analytical work, pharmaceutical industry | Industry, education |
The operating environment affects the choice of laboratory scales
In many laboratory and production environments, measurement accuracy can be disrupted by environmental factors such as vibrations, temperature fluctuations, or air currents. In demanding environments, choosing a scale that withstands humidity and temperature changes and includes features such as a draft shield to minimize the effects of air movement is essential.
Particularly when selecting a micro scale, environmental conditions must be carefully considered. A draft shield and specialized table solutions to reduce vibrations and air movement may be necessary to ensure stability. Precision scales are well-suited for fluctuating conditions, often equipped with durable structures that make them ideal for field and industrial use. Most analytical scales, on the other hand, feature built-in check weights, automatic calibration functions, and draft shields to ensure reliable measurements.
Features of laboratory scales ensure smooth operation
Traceability of measurement data is a crucial requirement, particularly in highly regulated industries such as the pharmaceutical sector. Modern laboratory scales offer advanced data transfer options, including USB, Bluetooth, and WiFi connectivity, providing efficient ways to store and share measurement results, reducing errors, and enhancing comprehensive data management.
Ease of use and efficiency are also important considerations when choosing a laboratory scale. Automated functions such as programmable settings and automatic doors speed up workflows and reduce the risk of errors. For example, high-quality Sartorius laboratory and precision scales – included in Tamtron’s offering only in Finland – combine intuitive user interfaces with ergonomic design. Sartorius is globally recognized for its innovative and high-quality laboratory scales designed to endure even the most demanding environments.
Calibration and maintenance are the foundation of measurement accuracy
Calibration and maintenance are central to the upkeep of laboratory scales. They ensure that measurement results remain accurate and traceable while helping extend the scale’s lifespan and maintain its reliability.
Regular calibration is essential for maintaining measurement accuracy and device performance. It allows for the evaluation of precision and helps minimize deviations. Accredited calibration connects measurement results to international standards.
Maintenance tasks performed during calibration, such as removing dirt, extend the device’s lifespan and enhance its operational reliability.
