Product Description
The MRC Lab part number MGB-21P Micro Balance for Pipette Calibration is designed to achieve requirements of mass measurements with high precisions.
Applications
- Filling,
- Check weighing,
- Percentage,
- Statistics,
- Air Buoyancy correction,
- Infrared sensors,
- Pipette Calibration,
- GLP Procedures.
Features
- Internal automatic calibration,
- Readability from 1μg,
- Consists of two major parts - an electronic system and a precise mechanical measurement system, kept in a separate enclosure,
- Made of glass and steel which eliminates the influence of electrostatics on the weighing process,
- Display of 5.7” touch.
