When you're shopping for a lab balance, the early decision usually comes down to capacity versus readability: how much sample you need to weigh and how fine the result has to be. The Mettler Toledo XSR1202S Precision Balance is listed with a 1210 g capacity and 0.01 g readability, and it carries a price of USD 1,999.00.
Quick Verdict
If your protocols require top-loading weighing with 0.01 g resolution and your loads stay under 1210 g, this balance is a straightforward fit. The automatic internal calibration (FACT) is a useful feature because it reduces the chore of manual calibration with external weights. The unit is described as being in exceptional cosmetic and working condition, and it has reportedly been professionally inspected, thoroughly cleaned, and fully tested.
Who It Suits
This balance is intended for biological laboratories, and the broader description points to pharmaceutical, biotechnology, research, quality control, and industrial settings. It's well suited to media preparation, buffer making, sample formulation, and checkweighing tasks where a top-loading pan makes sample handling easy.
What Stands Out From the Listed Details
The two numbers you'll see first are 1210 g and 0.01 g. That combination means you can weigh small research samples and still handle larger industrial quantities without switching instruments. The FACT automatic internal calibration is a notable convenience, and the top-loading design lets you set containers directly on the pan without a draft shield slowing you down. The description also emphasizes a professional inspection and full testing.
Meaningful Trade-Offs
The 0.01 g readability is precise, but it is not in the analytical balance category, where readability typically reaches 0.1 mg or finer. If your work hinges on sub-milligram differences, this won't replace a microbalance. As a used instrument, the specific unit's condition will matter more than the model's general reputation.
Bottom Line
The Mettler Toledo XSR1202S is a direct match for labs that need a top-loading precision balance with 0.01 g readability and 1210 g capacity. At USD 1,999.00, it's a significant investment, but the automatic internal calibration, top-loading convenience, and described inspected condition make it worth a close look.
Mettler Toledo XSR1202S Precision Balance (1210 g / 0.01 g)
This precision balance offers a 1210 g weighing range and 0.01 g readability. It's a top-loading model from Mettler Toledo's Excellence Series. The description notes that it has been professionally inspected, thoroughly cleaned, and fully tested, with an exceptional cosmetic and working condition. It's aimed at biological laboratories and fits applications that need repeatable 0.01 g measurements. Consider this if your lab's maximum load is around 1.2 kg and you want automatic internal calibration. The main limitation is the 0.01 g readability itself, which means you should pair it with a finer analytical balance if you ever need sub-milligram accuracy.
