Sartorius Practum 513-1S Laboratory Balances

This listing is for 1 of 3 Sartorius Practum 513-1S Laboratory Balances. The unit is in full working condition and is ready for immediate release. The Practum series is described by Sartorius as offering “best value for your money, without compromises in precision and reliability.” The model 513‑1S is one of the higher‑capacity versions of the Practum range: a capacity of 510 g, with a readability (resolution) of 0.001 g (i.e., ±1 mg) for that capacity. It uses the typical features of the Practum line: rugged housing (aluminium die‑cast base and ABS housing) and technology built for standard applications. Connectivity: has a Mini‑USB interface for outputting data to a PC or compatible printer. Weigh‑below hook capability (for e.g., hanging weights beneath the balance) is supported. A front level bubble and adjustable feet support easy leveling, which improves accuracy and repeatability. Mechanical overload protection is built in to help ensure durability. The Practum 513‑1S is well‑suited for standard analytical/precision weighing tasks in laboratories where you need to weigh up to ~ 510 g with 1 mg resolution. Typical use‑cases: formulation work, general sample weighing, quality control, density determination, routine laboratory tasks. The documentation mentions modes like counting, percent weighing, averaging and “unstable conditions” for the broader series. Because of its resolution and capacity, it's a good fit when you don’t need ultra‑fine microgram resolution but need relatively high capacity with milligram resolution.
