Radwag general laboratory equipment

Buying guide

Choosing a Radwag general laboratory equipment

The first decision is the one that separates the Radwag lines from each other: readability against capacity. Fix the smallest increment the work genuinely needs before looking at anything else. If analyses call for 0.1 mg steps, the AS analytical line is the starting point and its limited capacity is a constraint to plan around, not a flaw. If the work is batching reagents at a milligram or coarser, a PS or WLC precision balance gives the capacity an analytical balance cannot, and paying for analytical resolution would be wasted. For moisture determination the MA series is a separate purchase, not a balance with an accessory, and should be chosen on its drying temperature range and heating method.

On a used Radwag unit, check what ages rather than what is cosmetic. Ask the seller to confirm whether an internal adjustment mass is present and functioning, since this is the part that keeps a balance in specification between external calibrations and its failure is not visible from the outside. For any balance, a recent calibration record and evidence of a stable zero and repeatable readings are what a seller should be able to show. Weighing pans, draft shield glass and levelling feet are replaceable; the load cell and the adjustment mechanism are not, so weight the inspection toward those.

Price breaks down along the same readability and capacity axis that separates the series, with internal adjustment and higher resolution pushing a given model up the band. A compatibility point specific to this maker: Radwag weighing terminals and platforms are sold as matched pairs within a series, so a terminal from one line does not always drive a platform from another. When a listing is a terminal or a platform on its own, confirm which platform or indicator it was built to work with before assuming it completes an existing system. Parts can be sourced via Questpair, and where warranty matters it is arranged in consultation for the specific listing.

Radwag balance and scale series on Questpair

Among the listings that specify a type, the common ones are the industrial scale, the platform scale, the precision balance, the weighing terminal and the analytical balance. Radwag's own series map onto those types in a fairly direct way. The AS series sits in the analytical balance group, built for four-decimal and sometimes five-decimal readability and aimed at sample preparation, standard solution work and quantitative chemistry. Precision balances are covered by the PS and WLC series, the first with higher resolution and internal adjustment, the second a simpler line for general bench weighing where a milligram or a centigram is enough. The MA series moisture analysers form their own group, combining a balance with a heating element for loss-on-drying measurements. At the fine end, the XA, MYA and UYA series extend into micro and ultra-micro weighing, though those appear less often in a general laboratory intersection than the bench and analytical lines. The industrial scales, platform scales and weighing terminals are the heavier end of the same portfolio, where the terminal is the indicator and control unit paired with a separate weighing platform.

Where the AS, PS and WLC lines diverge

The deciding specification between these lines is readability set against capacity, and the two move in opposite directions. An AS analytical balance reads to 0.1 mg or 0.01 mg but tops out at a few hundred grams, so it suits small samples weighed precisely. A PS precision balance trades that resolution for capacity, typically reading to 1 mg or 10 mg across a range that can reach several kilograms, which fits reagent batching and formulation work. The WLC line sits below the PS on resolution and is the choice where throughput and durability matter more than the last decimal. Internal adjustment is the other dividing feature: higher AS and PS models carry an internal calibration mass that compensates for temperature drift automatically, while entry WLC units rely on external calibration weights. For moisture work the MA series is specified by drying temperature range and balance resolution rather than capacity, since the sample mass is small. Matching the line to the work means fixing the required readability first, then checking the maximum load, then deciding whether automatic internal adjustment is worth the higher price.
