Buy laboratory balances: precise weighing technology with service from a single source
Laboratory balances and fine balances are used wherever measurement results must be reliable, reproducible and documentable. In the ESSMANN scale shop, you will find suitable solutions for laboratories, research, pharmacies, development and quality control.
Depending on the application, choose between analytical balances with fine readability, precision balances for everyday laboratory use, microbalances for the smallest sample quantities and moisture analyzers for moisture analysis.
Choosing the correct weighing range and readability
The weighing range must be suitable for the largest sample expected, including the container, weighing pan or tare. Selecting a maximum load that is too low will quickly lead to overloading or impractical operation in day-to-day use. At the same time, the balance should not be selected solely on the basis of its maximum capacity: the finer the weighing required, the more important readability, repeatability and the actual conditions at the installation site become.
Readability indicates the increments in which the weight value is displayed, for example in 0.1 g, 0.01 g, 0.001 g or finer. However, it is not synonymous with measurement accuracy on its own. Reliable measurement results also depend on repeatability, linearity, adjustment, calibration status, operation and environmental influences.
Wind protection, installation location and operation
The smaller the sample and the finer the resolution, the greater the impact of draughts, vibrations, temperature changes, electrostatic effects or unstable workbenches. A draught shield is advisable or necessary for precision weighing. The balance should be placed on a stable, level surface, as far away as possible from doors, windows, heat sources, ventilation outlets and equipment that vibrates heavily.
Before starting work, the laboratory balance must be levelled. To do this, adjust the levelling feet so that the bubble in the spirit level is centred. The balance should then be allowed to acclimatise sufficiently and, if required, be adjusted. Clean weighing vessels, correct taring and careful handling of the sample are simple but crucial prerequisites for reproducible measurement results.
Adjustment, calibration and control of measuring equipment
Adjustment, calibration and verification are different processes. Adjustment involves setting the balance so that it operates within the specified tolerances. Calibration documents the measurement deviation relative to a traceable standard. It is particularly relevant for quality assurance, test equipment monitoring, audits, ISO 9001 processes and applications related to GMP or GLP.
A DAkkS calibration may be advisable where measurement results need to be documented to a particularly high standard and verified with traceability. However, it is not automatically required for every laboratory balance. For simple internal checks, an ISO calibration or a regular internal check using suitable test weights may be sufficient, provided this is in line with quality management requirements.
This should be distinguished from verification. Verification is regulated by law and is only relevant if the specific application is subject to verification requirements, for example where weight values are of legal or commercial significance. Calibration does not replace verification where verification is mandatory.
Interfaces and documentation
In laboratories where measurement data must be documented, interfaces may be more important than they initially appear. USB, RS-232, Ethernet or other output options can help to transfer measurement data to printers, laboratory software or a quality management system. Before purchasing, you should check whether only individual weighing readings need to be output, or whether details such as the user, sample, date, time, calibration status and other information are required.
Avoiding typical bad buys
People often make the wrong purchase when they focus solely on the price or the displayed accuracy. A laboratory balance with a very high-resolution display does not automatically deliver better results if it is placed on a vibrating table, used without a draught shield or not checked regularly. An insufficient weighing range is equally problematic when working regularly with heavy vessels.
For very precise weighing, analytical balances or microbalances are more suitable than standard laboratory balances. For larger samples, harsher working environments or frequent batch weighing, a precision balance may be the better choice. For simple training applications, school balances may be sufficient if no documentation subject to audit is required. If moisture content or dry matter is also to be determined, moisture analysers may be the appropriate solution.
Thinking ahead about service, calibration and operation
When it comes to laboratory balances, it is not just the choice of instrument that matters. Test weights, calibration intervals, cleaning, spare parts, repair options and documentation are all part of day-to-day operation. ESSMANN combines its online balance shop with the specialist expertise of a balance manufacturer and provides support with queries regarding selection, calibration services, maintenance, balance servicing and balance repairs. For applications subject to audit requirements, the appropriate type of calibration should be clarified before purchase.
