Ergonomic Pipette Calibration with METTLER TOLEDO Analytical Balances

In response to international guidelines and customer requirements, weighing specialist METTLER TOLEDO has developed an integrated 100 ml evaporation trap for use with the XP and XS balance ranges. Using the same trap design as METTLER TOLEDO’s dedicated pipette calibration systems, this accessory allows customers to rapidly switch between analytical weighing and pipette calibration functions using the world-leading range of XP and XS Analytical Balances.

The international standard for pipette calibration, ISO 8655, recommends use of an evaporation trap and emphasizes that trap geometry and use of a lid are key to accurate pipette calibration. The new 100 ml evaporation trap exceeds these recommendations and its high capacity is unique to the market, offering unrivalled calibration performance for pipette volumes from 10 μl up to 10 ml.

Both trap geometry and pipetting container design are optimised to achieve minimal evaporation and high reproducibility, eliminating the need for draft shields and providing unobstructed pipetting into the vessel. The 100 ml evaporation trap offers accurate pipette calibration to customers not requiring a dedicated calibration instrument, and completes METTLER TOLEDO’s portfolio of pipette calibration solutions for all applications.
