fixed volume pipette with precision calibration function

Fixed Volume Pipette

Main Features

1. Air displacement principle: Delivers precise, repeatable volume via robust piston mechanism.
2. Centered, enlarged pipetting button: Ergonomic and easy for thumb operation—smooth, stable piston movement.
3. Ergonomic finger rest: Fits all hand sizes and reduces fatigue during extended use.
4. Clear capacity markings: Instantly visible—prevents mix-ups of different volume ranges.
5. Fully autoclavable: Sterilize entire pipette at 121°C for 20 min—no disassembly needed.
6. Slender rod design: Easily accesses narrow containers like centrifuge tubes and test tubes.
7. Universal cone: Compatible with tips from major brands—eliminates repeated sourcing headaches.
8. Quick calibration: Simple tool-based calibration keeps accuracy long-term.

Core Advantages

1. Fixed volume, minimal error: Factory set and calibrated—error control better than ±1%.
2. Simple operation: No adjustments required—ideal for repetitive same-volume tasks.
3. Durable build: High-quality plastics and ceramic piston—corrosion-resistant, long lifespan.
4. Low training cost: Easy for students/technicians to learn and use in teaching, QC environments.

Working Principle

Operates via air displacement. Button press moves piston down to expel air; release generates negative pressure to aspirate liquid; press again to dispense. Volume is preset at the factory and not adjustable—ensures stable accuracy over time.

Typical Applications

1. Life science: PCR, DNA extraction, ELISA, enzyme analysis—standard, repeated sample removal.
2. Biochemical/QC testing: Batch testing, SOPs for food, pharma, environmental labs.
3. Education/training: Simple for students and teaching labs—reduces operational errors.
4. Hospital/clinical diagnostics: Fast, accurate, repeated sample addition for analysis workflows.
