FAQ

For which applications can I use automatic weighing?

Multiple applications in various industries can benefit from automatic weighing, such as bottling for sales, sample preparation, capsule filling, or screening. Automatic scales are widely used in industries such as fine chemicals, pharmaceuticals, CROs, CDMOs, or testing labs.

What is an automatic weighing balance?

The automatic balance can automatically dispense powders and liquids with high accuracy, in addition to performing solution preparation and serial dilutions. It improves workflows of sample preparation in the lab for qualitative and quantitative analysis of various analytical techniques including HPLC, GC, ICP, and NMR.

How can I improve the efficiency of sample preparation?

An automatic balance greatly reduces time spent on sample preparation. To further increase efficiency, an automatic balance can be upgraded with a sample changer, which can prepare samples while the operator focuses on other tasks in the lab.

What is gravimetric sample preparation?

Gravimetric sample preparation is weighing a sample, either manually or using automation, and then delivering the required amount of solvent to achieve a desired concentration. The solvent amount is calculated based on the actual amount of sample weighed and measured by its weight rather than volumetrically.

What is the lowest amount I can weigh automatically?

METTLER TOLEDO automatic balances (XPR226DRQ and XPR106DUHQ) show reliable performance for target weights above 0.30 mg. At this weight, 93% of measurements did not deviate more than 20% from the target weight.

How much time and sample can I save using automatic weighing?

The exact savings can be counted using a return-on-investment calculator. It can vary depending on the task time when working manually and sample costs. Generally, approximately 75% can be saved on sample and time when preparing the samples automatically.

How can I safely weigh potentially hazardous samples?

An automatic scale is the perfect solution for weighing hazardous samples. The system can work with limited technician interaction and can be easily placed in safety enclosure or glove box.

What are the tricks to improve capsule filling?

An automatic balance with a sample changer is a useful solution for filling small batches (up to a few hundred) of capsules. Every capsule can be filled with a different amount of samples if necessary. This automated solution includes a specially designed powder dosing head in order to avoid spillage, error, waste, and save time.
