Improve accuracy and safety with this automatic balance
The new XPR Automatic Balance (photo) incorporates state-of-the-art active machine learning to deliver accurate powder weighing. Safety when weighing potentially toxic or active substances is of paramount importance in industries such as chemical, pharmaceutical and biotechnology. The XPR Automatic supports accuracy, repeatability and safety by dosing from an enclosed head into target vials or capsules with openings as small as 6 mm in diameter. It then uses live feedback to learn a substance’s flow characteristics and improve dispensing efficiency in real time. This can be particularly effective when combined with a sample changer that can process as many as 30 samples in one automated run. Direct dosing reduces the kind of airborne exposure risk to lungs and eyes that spatula use represents. Spill risk is also eliminated, as is the need to repeatedly open the balance door and transfer compounds from the main container into a secondary container. The balance can be operated inside a glove box or safety enclosure. — Mettler Toledo, Columbus, Ohio
