The TopPette-Mechanical Pipettes/MicroPette Plus Autoclavable Pipette series delivers precise liquid handling for laboratory applications requiring accuracy and sterility. These mechanical pipettes feature volume ranges from 5μl to 20μl with systematic error specifications of 0.6-3.0% and random error control from 0.05μl to 0.12μl, providing reliable micropipetting performance for analytical and research protocols.
The autoclavable design supports sterile technique requirements in microbiology, cell culture, and analytical chemistry applications. Multiple volume configurations accommodate diverse liquid handling workflows, from precise analytical measurements to sample preparation protocols requiring sterile conditions.
How It Works
Mechanical pipettes operate through positive displacement piston mechanisms that draw and dispense precise volumes of liquid. The user-operated plunger creates controlled pressure differentials within the pipette body, enabling accurate liquid aspiration and dispensing through disposable tips. Volume selection is achieved through mechanical adjustment systems that modify the piston stroke length.
The MicroPette Plus series incorporates precision-machined components to maintain volumetric accuracy within specified tolerances. Systematic error control ensures reproducible volume delivery, while random error minimization provides consistent precision across repeated measurements. The autoclavable construction allows complete sterilization at standard autoclave conditions without compromising mechanical precision.

Practical Tips
Perform gravimetric calibration verification using distilled water at room temperature before critical analytical work.
Why: Temperature and liquid properties affect volumetric accuracy and should be controlled for precise measurements.
Disassemble autoclavable components according to manufacturer procedures before steam sterilization to prevent damage.
Why: Improper autoclaving can compromise seals and mechanical precision of the pipette mechanism.
Pre-wet pipette tips before aspirating samples to improve volumetric accuracy and reduce systematic errors.
Why: Dry tips can retain sample volume due to surface tension effects, particularly with aqueous solutions.
Check tip seating and plunger movement if volumetric accuracy appears compromised during use.
Why: Loose tips or mechanical binding can introduce systematic errors that exceed specified tolerances.
Use consistent aspiration and dispensing techniques to minimize operator-induced variability in measurements.
Why: Human technique variation can exceed instrument precision limits if not standardized across operators.
Allow adequate cooling time after autoclaving before handling pipette components to prevent thermal injury.
Why: Metal and plastic components retain heat after sterilization cycles and require cooling for safe handling.

Background reading relevant to this product:
What is the volumetric accuracy specification for each volume range?
The 5μl model has 2.0% maximum systematic error, while both 10μl and 20μl models have 3.0% maximum systematic error, with random error ranging from ±0.06μl to ±0.12μl depending on volume.
Can these pipettes withstand standard autoclave sterilization cycles?
Yes, the MicroPette Plus series is designed for autoclave sterilization, though specific temperature and pressure limits should be confirmed from the product datasheet.
What tip compatibility should I consider for these pipettes?
Consult product specifications for recommended tip types and ensure proper tip seating for maintaining volumetric accuracy within specified tolerances.
How frequently should calibration verification be performed?
Calibration frequency depends on usage intensity and accuracy requirements; perform gravimetric verification using distilled water when accuracy is critical for analytical protocols.
Are these pipettes suitable for organic solvents and aggressive chemicals?
Chemical compatibility depends on internal component materials; consult chemical resistance charts in the product documentation before use with solvents.
What maintenance procedures are required for optimal performance?
Regular cleaning, proper storage, and periodic calibration verification maintain accuracy; autoclavable components should be properly disassembled before sterilization cycles.
