A&D Weighing FX-300i-PT Pipette Accuracy Tester, 320 g x 0.001 g

The A&D FX-300i-PT is designed for in-house gravimetric testing of pipette accuracy and repeatability. Instead of sending pipettes out for every routine check, laboratories can dispense water into the tester, measure its mass, and use A&D’s software to evaluate pipette performance against selected criteria.

The FX-300i-PT has a 320 g weighing capacity with 0.001 g (1 mg) readability. A&D specifies 1 mg repeatability, ±2 mg linearity, and approximately 1-second stabilization, making it particularly useful for routine or simplified pipette verification where 1 mg resolution is appropriate.

Yes. A&D designed its pipette accuracy testing system around the gravimetric method, and the accompanying WinCT-Pipette software supports ISO 8655-oriented test conditions. However, whether the FX-300i-PT itself provides sufficient resolution depends on the pipette volume and required permissible error; A&D positions its higher-resolution AD-4212 PT models for more demanding small-volume testing.

Evaporation can reduce the mass of dispensed water while a pipette test is being performed, introducing measurement error. The supplied evaporation trap helps maintain higher humidity around the sample container and minimizes evaporation-related effects, supporting more dependable gravimetric pipette measurements.

Yes. The system includes WinCT-Pipette, A&D’s dedicated pipette-testing software. It can evaluate systematic error (accuracy) and random error (repeatability), provide automatic pass/fail judgments, and store information such as test date, operator, pipette details, environmental conditions, and measurement results for traceable recordkeeping.
