FDA-compliant weighing table made entirely of stainless steel

Precise work is the top priority in pharmaceutical production - this also includes the extremely precise weighing of the smallest quantities of products or active ingredients.

Where exact measurement results are required, weighing tables or anti-vibration tables are used. These tables are designed in such a way that they absorb vibrations, e.g. caused by movements in the environment, thanks to their enormous weight and structural stability and decoupling, and stabilize the measuring devices such as analysis and microbalances during use, thus preventing measurement inaccuracies as best as possible.

An anti-vibration or weighing table usually has an integrated stone plate that is mounted on rubber blocks. Such a stone or granite slab is increasingly presenting clean room operators and pharmaceutical manufacturers with the problem that FDA approval is not available for a natural material such as granite.

Friedrich Sailer GmbH, as an innovative outfitter for cleanrooms and pharmaceutical companies, has developed a solution for this: the Sailer weighing table made of stainless steel. This anti-vibration table, which is suitable for cleanrooms and is made of material AISI 304, has the Sailer-typical brushed finish with a surface roughness of Ra < 0.8 µm. Due to its densely laser-welded stainless steel table top construction with a filling of ultrahigh performance concrete (UHPC) and its high weight of 130 kg, it is extremely low in vibration. The upper plate is also vibration-decoupled from the substructure via 4 dampers made of FDA-compliant plastic. All of the materials used for the table are FDA-compliant, as is the surface quality.

The Sailer weighing table ensures maximum stability of a scale and reduces vibrations to a minimum. Tests with a high-performance analytical balance from Mettler Toledo (model XPR225DR) have shown that measurement accuracies of 0.1 mg to four decimal places are stably achieved in both cleanroom and uncontrolled conditions.

This means that there is now the possibility of doing without non-FDA-compliant material in the pharmaceutical environment and using a solution for safe and precise weighing that meets all the specifications for a clean room-compatible design.
