Sample Prep Solutions for HPLC & More

Quality Control (QC) Is a Critical Step in the Pharmaceutical and Biopharmaceutical Industry

Every pharmaceutical manufacturer must demonstrate that their products are consistently manufactured, safe, potent, and pure. The number of tests that must be run by QC labs continues to rise to meet the ever-increasing QC requirements of global regulatory agencies.

Our analytical sample preparation solutions combine our legendary quality and reliability with our design wisdom to provide the very best in high-pressure liquid chromatography (HPLC), liquid chromatography–mass spectrometry, ion chromatography (LC-MS, IC), or inductively coupled plasma mass spectrometry (ICP-MS) filtration solutions.

  • Fast, simple, & economical
  • Low retention volumes & maximal recoveries
  • Almost zero leachables or extractables

Pharma Compliant Weighing and Sample Management

In the biopharmaceutical industry, scientific innovations are occurring very rapidly and are affecting all aspects of drug development and manufacturing, including the regulatory framework. As a laboratory balance manufacturer, we are committed to develop products which integrate the newest technologies and follow the latest pharmacopeia requirements. 

Quality Control in the biopharmaceutical industry includes the testing of raw materials, product intermediates and final drug products to ensure they meet the specifications related to their safety, stability, and efficacy. Typical quality control processes that we support with our high-end laboratory balances include sample preparation and management. See how we can address your weighing challenges in your QC process.

Sartorius Solutions for Laboratory Weighing

Pharma Compliant Weighing

Sartorius’s Cubis® II is designed to follow US FDA data integrity principles that require data to be accurate, legible, contemporaneous, original, and attributable (ALCOA).

The Cubis® II balance, with the Pharma package, contains all the technical controls to support full compliance with common regulations.
