Variable Volume Micropipette (10–100 µL) — Apex Labs

The Variable Volume Micropipette (10–100 µL) is a fundamental precision instrument used across molecular biology, clinical diagnostics, and chemical research for the accurate transfer of liquid micro-volumes. Operating on the air displacement principle, this tool utilizes a high-performance piston to create a vacuum for precise aspiration and dispensing into disposable tips. Its adjustable volume range is a versatile solution for tasks like PCR master mix preparation, ELISA assays, and serial dilutions, allowing a single device to replace multiple fixed-volume alternatives.
