Weighing Technology for Filling
Small-Sized Containers


Weighing. It's the easiest and most accurate method for filling syringes, vials, ampoules and tubes. The new guideline provides practical know-how to achieve the best gravimetric filling results.




Weighing is typically the most accurate and reliable measuring method for filling, formulation, dosing and batching processes whether you work with liquids, solids or gas. The method is also highly hygienic and sanitary to eliminate contact with stored substances and enhance operator safety by reducing cross-contamination risk. This can be a huge benefit in highly regulated industries such as pharmaceutical, food, chemical and cosmetics production.

Fill-by-Weight Advantages

Filling by weight has many advantages compared to volumetric filling with flowmeters or other such devices, including accuracy, ease of calibration, and facilitation of statistical process control and traceability. A huge variety of materials are filled and a corresponding variety of fillers used; weighing is the one universal technology that can be used regardless of the material or container characteristics.
