RADWAG is a well-established manufacturer of precision instruments specializing in laboratory balances, moisture analyzers, and advanced weighing systems for regulated and industrial research environments. Its portfolio of laboratory balances supports analytical weighing, sample counting, and routine mass determination where accuracy, repeatability, and product quality are critical.
The RADWAG lineup includes analytical balances, ultra and microbalances, precision balances, high capacity precision balances, and mass comparators designed for applications requiring tight tolerance ranges and consistent measurement precision. Features such as internal calibration, air buoyancy compensation, stainless steel weighing platforms, and stable measurement ranges help ensure reliable results under temperature variations and demanding laboratory conditions. These laboratory devices are widely used in scientific research, chemical engineering, and industrial research workflows.
RADWAG moisture analyzers and moisture balances support moisture content determination using Loss on Drying methods for powders, raw materials, and production samples. Systems such as the MA 5Y Moisture Analyzer and MA 50.X2.A enable dry mass determination, relative moisture content analysis, and controlled sample drying through programmable drying profiles, temperature control, and automated chamber operation. Moisture analyzer accessories, disposable pans, heating elements, and finish modes support consistent sample weighing across food research and manufacturing processes.
MSE Supplies provides access to RADWAG laboratory balances, moisture analyzers, and precision weighing systems through reliable sourcing and a curated product selection, enabling laboratories and production facilities to implement dependable weighing solutions that support accuracy, compliance-driven processes, and long-term operational confidence.
What a Balance Specification Does Not Tell You About the Room It Will Live In
Readability is the number on the datasheet and the one most purchase decisions turn on. It is also the specification least likely to be achieved in practice, because it describes the instrument under conditions the room rarely provides. A balance reading to five decimal places on a bench near a door, under a vent, beside a centrifuge, will not deliver five usable decimal places. The limiting factor is almost never the instrument, which is why installation conditions deserve as much attention as the model number.
The Conditions That Consume Resolution
Air movement, vibration, temperature gradient and static each erode the last digits before the sample is even loaded. Draught shields address only the first. A bench that transmits footfall or a nearby compressor removes resolution that no amount of averaging restores, and a sample warmer than the surrounding air generates convection that reads as slow drift. Allowing a sample to equilibrate to room temperature before weighing costs a few minutes and recovers more precision than most instrument upgrades, which makes it the cheapest available improvement in any weighing protocol. Specifying an analytical balance for the environment it will actually occupy, rather than for the best case, is what makes the quoted readability meaningful in daily use.
Sample State Before It Reaches the Pan
Mass is a proxy for something else in most protocols, and the assumption linking them is usually dryness. Hygroscopic powders gain mass between the oven and the pan, so the number recorded reflects ambient humidity rather than composition. A karl fischer moisture analyzer resolves that directly by measuring water content instead of inferring it, which converts a persistent source of scatter into a measured quantity. The lab consumables used to hold and transfer the sample matter too, since static on a plastic weighing boat shifts readings at the microgram level.
Calibration Against Traceable References
A balance that repeats well is not necessarily accurate, and the difference only appears against a traceable reference. Calibration masses from a general testing supplies range establish that link, and the same discipline applies to every instrument reporting a number, including a conductivity meter checked against standard solutions. Where weighing feeds preparation directly, IKA rotary evaporators and stirrers depend on that mass being right before concentration means anything.

What to know before you buy
For labs looking for RADWAG in the USA, this collection lists the main RADWAG weighing lines, from microbalances to weighing modules and terminals. Analytical options include the AS.R2 PLUS analytical balances and the AS.5Y from the ELLIPSIS 5Y series. For the smallest samples, there are the XA.5Y.M microbalances.
Precision balances, such as the PS.R and PS.X7 series, handle larger loads at coarser readability, and the WLC series adds more capacity. For water content, the MA R, MA 5Y, MA 5Y.IC and PMV 5Y moisture analyzers dry and weigh samples in one step.
Industrial and integration users can pick MAS and MPS weighing modules, the MWLH 10 electromagnetic compensation module, PUE weighing terminals, HRP high resolution scales and the PA-04/H automatic feeder. For help picking a balance, see key factors that determine a quality balance.
Frequently Asked Questions
Do I need an analytical balance or a precision balance?
Analytical balances read to 0.1 mg or finer and suit sample prep for analysis and standards. Precision balances have lower readability but higher capacity, so they suit routine weighing and larger containers. Compare readability and capacity on the AS.R2 PLUS and PS.R pages.
When do I need a microbalance?
Use a microbalance when sample masses are in the milligram range or smaller, for example filters, small catalyst loads or thin film samples. The XA.5Y.M microbalances are built for this work. They need a stable bench and controlled airflow.
Which RADWAG moisture analyzer should I choose?
The MA R series covers routine moisture checks. The MA 5Y series is built on the 5Y platform, and the MA 5Y.IC version is listed separately. The PMV 5Y is another option. Compare drying methods, capacity and readability on each product page.
What are weighing modules and terminals used for?
Weighing modules, such as the MAS.1 IP54 module or the MWLH 10, build weighing into a production line, test rig or automated system. PUE terminals, such as the PUE 7.1, display results and connect a scale to other equipment.
How do I order several balances for one lab?
