single channel pipette

single channel pipette with adjustable volume range

Manual adjustable single-channel pipette is a basic laboratory pipetting tool, relying on finger pressure piston operation, suitable for quantitative pipetting of micro-volume liquid.

Description

Manual Single Channel Pipette

Main Features

  1. Air displacement principle: Precise pipetting/drainage via mechanical piston control—covers 0.1μL to 10mL models.
  2. Center-mounted piston button: Ergonomic for natural thumb movement—reduces misoperation, improves efficiency.
  3. Manual single-channel: One liquid channel for high-frequency, precise single-reagent tasks.
  4. 4-digit volume display: Clear, accurate settings—minimizes errors.
  5. Ergonomic design: Finger rests and 12.5mm short stroke—low fatigue, comfortable for long use.
  6. Universal tip compatibility: Cone fits most mainstream tips—no repeated replacements needed.
  7. High-temp autoclave sterilization: Sterilize whole pipette at 121°C—no need to disassemble.
  8. Anti-misadjustment: Range lock protects against accidental volume changes.
  9. Chemical-resistant construction: Ceramic tip cone/piston—durable, corrosion-resistant.

Advantages

  1. Manual control: Reliable, no power needed—ideal for field/lab use.
  2. Simple maintenance: Robust mechanics—routine cleaning and periodic calibration only.
  3. Stable accuracy: Easy calibration, no tools required—fine-tune as needed.
  4. Easy to use: Intuitive operation—novices can get started quickly.
  5. Cost-effective: No electronics, low failure rate—great for bulk lab purchases.
  6. Efficient: Lightweight/sensitive feedback—no fatigue during extended use.
  7. Multi-range: 9 specs from 0.1μL to 10mL—covers diverse experimental needs.
  8. International standards: CE certified—complies with EU lab equipment specs.

Working Principle

Air displacement: User presses piston to expel air, then releases to create negative pressure and aspirate liquid; pressing again dispenses liquid. Entire process is manually controlled for precise volume handling.

Typical Applications

  1. Molecular biology: DNA extraction, PCR setup, agarose gel prep.
  2. Drug R&D: Reagent mixing, dilution, candidate compound blending.
  3. Lab analysis: Clinical testing, biochemistry, microbiology.
  4. Food/environmental: Sample dilution, pollutant/water analysis.
  5. Education/training: Teaching, research beginner training.
