Guide and selection support
Drying balances are used for the precise determination of moisture content in material and food samples. They work by controlled drying of the sample using heat, followed by weighing the dried sample to quantify moisture loss.
When choosing a drying balance, key criteria include accuracy, temperature control, weighing capacity, and user convenience. Various models offer different programs for drying time and method, enabling adaptation to specific sample characteristics.
LabFinder supports users in targeted searches for suitable drying balances for diverse laboratory requirements and provides orientation regarding application areas and technical features of the devices.
Application and Benefits
Drying balances are used for rapid and accurate determination of moisture content in small to medium sample quantities. They are applied in quality control, materials testing, and research to precisely determine water or moisture content in foods, plastics, pharmaceuticals, and other materials. Samples are dried using halogen lamps, then reweighed to establish the exact moisture loss.
Selection Criteria
Key selection aspects for drying balances include weighing performance and sensitivity, type of temperature control, and the availability of individually programmable drying cycles. User interface, documentation options, and compatibility with laboratory software can also be relevant. Depending on sample type and requirements, the required drying times and temperatures can vary.
Variants and Measuring Principles
The fundamental measuring principle combines halogen-based drying with high-precision load cells for moisture analysis. Different models are available, distinguished by their capacity, timing options, temperature ranges, and degree of automation. Some devices allow standardized or user-defined program selection to tailor the process for individual samples.
Calibration and Maintenance
Regular calibration is necessary to ensure precise measurement results. Maintenance typically involves cleaning the weighing hardware and heat source as well as performing regular system checks according to manufacturer specifications. Stable testing environments and mechanically protected components support long-term accuracy.
Limitations of Application
Drying balances are designed for small to medium sample volumes and are suitable for materials that do not experience chemical decomposition under heat. For substances with volatile components or highly heat-sensitive samples, alternative methods of moisture determination should be considered. The accuracy of the load cell constitutes the fundamental analytical limit.

Frequently asked questions
How does a drying balance determine moisture content?
A drying balance dries a sample using halogen lamps and weighs it before and after the drying process. The difference in weight corresponds to the moisture loss, thus allowing the moisture content of the sample to be determined.
What types of drying balances are available?
Variants mainly differ in weighing performance, temperature ranges, programmability of drying times, and automation functions. Some models offer fixed programs, while others allow flexible, pre-settable programs.
What are the key selection criteria for a drying balance?
Key criteria are weighing performance and accuracy, temperature control options, ease of use, and the availability of individual drying programs suitable for the sample.
For which samples is it appropriate to use a drying balance?
Drying balances are suitable for samples where moisture content can be determined through thermal drying, especially for solid and semi-solid substances in small to medium quantities.
What are the limitations of moisture determination with a drying balance?
They are not suitable for highly heat-sensitive samples or substances with volatile components that do not solely lose water during drying. Additionally, the sensitivity of the weighing station limits the method’s analytical resolution.
