Sartorius (Germany) has developed a new range of Class M1 stainless steel calibration weights. Designed in cooperation with a pharmaceutical manufacturer, the new weights meet the health and safety requirements for lifting and carrying. The use of stainless steel was the starting point for the new design, to both avoid contamination and minimise marking on the customer’s electro-polished weighing platforms. The new stainless steel block shaped weights are available from Sartorius in 10kg or 20kg. The dimensions of the new weights are suitable for a gloved hand.
