Sartorius Secura laboratory balance

The Secura laboratory balance, developed by Sartorius for applications in regulated areas such as pharmaceutical labs, fulfills high-reliability requirements. The balance monitors ambient conditions automatically, thereby preventing handling errors and increasing reliability and consistency of the results.

Nine different models are available, covering weighing capacities from 120 g to 5.1 kg and a readability of 0.1 to 10 mg. The balance is equipped with assistance systems designed to prevent further processing of uncertain weighing results, which frequently occur through operating errors. If errors occur, the balance identifies the uncertain results and blocks their transmission.

The electronic LevelControl sensor ensures the balance is level, which is important for equipment monitoring and obtaining accurate readings. Non-compliance is indicated in the display and blocks output of the reading. Clear instructions in the display guide the user through the levelling procedure. Lab staff can easily level balances located in safety work benches or safety weighing cabinets without having to open the safe work area.

Balances have to be calibrated regularly as ambient conditions change. Once a specified time or temperature threshold is reached, the unit’s calibration and adjustment function, isoCAL, informs the user and automatically adjusts the balance using internal weights. Every adjustment is documented.

Every balance used in regulated areas has to meet the requirements specified by the FDA. Pharmaceutical labs have to determine the minimum sample weight according to the US Pharmacopeia on site and measurements may not fall below this limit. Sartorius service staff may determine this value during first operation of the balance and issue a minimum sample weight certificate. The value will be constantly displayed on the balance. If a measurement falls below the minimum sample weight, an alert will appear and the balance will block printout and transmission of the reading.

The weighing applications are represented as understandable icons on the touch screen. This allows users to launch any of the balance’s programs with the touch of a finger, without having to read the operating manual. The balance only displays the information required for the particular operation. The colour-coded information and action fields make operating errors near impossible. Settings that could change data output or the metrological performance can be password protected.
