Single Channel Fixed Pipettes provide precise liquid handling for laboratory applications requiring accurate volumetric transfers. These precision instruments feature fixed volume capacities ranging from 5 μL to 100 μL, with accuracy specifications tailored to each volume range. Each pipette model delivers consistent performance within defined tolerance limits, supporting quantitative protocols in analytical chemistry, molecular biology, and pharmaceutical research.
The pipettes incorporate ergonomic design principles to minimize operator fatigue during extended use. Volume-specific accuracy and precision specifications ensure reliable performance across the measurement range, with each model optimized for its designated volume capacity. The fixed volume design eliminates variable setting errors and provides consistent delivery characteristics essential for reproducible experimental protocols.
How It Works
Fixed volume pipettes operate on the air displacement principle, utilizing a piston mechanism to create controlled vacuum for liquid aspiration and positive pressure for dispensing. The piston moves through a predetermined stroke length calibrated to the specific volume capacity, ensuring consistent liquid transfer volumes. When the operating button is depressed, the piston creates negative pressure that draws liquid into the disposable tip through capillary action and atmospheric pressure differential.
Volume accuracy depends on proper tip attachment, consistent operating technique, and environmental factors including temperature and liquid properties. The fixed volume design eliminates mechanical variability associated with adjustable volume settings, providing enhanced repeatability for applications requiring identical transfer volumes. Each pipette undergoes factory calibration to meet specified accuracy and precision tolerances across its operational range.

Practical Tips
Perform gravimetric calibration using distilled water at 20°C with density correction factors for temperature variations.
Why: Accurate calibration verification requires controlled environmental conditions and appropriate reference standards.
Disassemble and clean internal components monthly when used with protein solutions or viscous samples.
Why: Protein buildup and sample residues can affect piston movement and vacuum integrity over time.
Pre-wet pipette tips by aspirating and dispensing sample solution 2-3 times before critical measurements.
Why: Pre-wetting equilibrates tip surfaces with sample, improving volume accuracy particularly for aqueous solutions.
Check tip seal integrity if dispensed volumes appear inconsistent or if air bubbles appear during aspiration.
Why: Poor tip seal allows air leakage that compromises volume accuracy and creates measurement variability.
Maintain consistent plunger depression speed and hold pipette vertically during aspiration and dispensing.
Why: Consistent technique minimizes operator-induced variability and ensures reproducible volume delivery.
Use appropriate tip types rated for chemical compatibility when handling organic solvents or corrosive solutions.
Why: Chemical compatibility prevents tip degradation that could introduce contamination or affect volume accuracy.
Replace tips between samples to prevent cross-contamination, especially when working with trace-level analytes.
Why: Sample carryover can compromise analytical results and introduce systematic errors in quantitative protocols.

Background reading relevant to this product:
What accuracy can I expect across the volume range?
Accuracy varies by model: 5 μL achieves ±0.4%, 10 μL and 20 μL achieve ±0.5%, and 100 μL achieves ±0.3%. Precision ranges from ±0.02 μL (5 μL model) to ±1.1% (100 μL model).
How do I maintain calibration accuracy over time?
Perform regular gravimetric verification using distilled water at controlled temperature. Clean internal components periodically and replace worn seals to maintain vacuum integrity.
Are these pipettes compatible with standard tip systems?
Consult product datasheet for specific tip compatibility. Most fixed volume pipettes accommodate standard conical tips appropriate for the volume range.
What factors affect dispensing accuracy?
Temperature variations, liquid viscosity, tip fit, and operator technique influence accuracy. Pre-wet tips with sample solution and maintain consistent plunger speed for optimal performance.
How do fixed volume pipettes compare to adjustable models?
Fixed volume designs eliminate mechanical variability from adjustment mechanisms, providing enhanced repeatability for applications requiring identical transfer volumes but limiting flexibility.
What maintenance procedures are recommended?
Regular cleaning with appropriate solvents, periodic seal replacement, and annual calibration verification maintain performance. Avoid aggressive chemicals that may damage internal components.
Can these pipettes handle organic solvents?
Compatibility depends on seal materials and internal components. Consult product datasheet for chemical resistance specifications before use with organic solvents.
