The TopPette-Mechanical Pipette is a precision liquid handling instrument designed for accurate volumetric measurements in laboratory applications. This mechanical pipette series offers multiple volume ranges with specific accuracy and precision specifications for each range, supporting precise liquid transfers in analytical and preparative workflows.
The instrument features a mechanical operation mechanism that provides reliable performance across different volume ranges, from microliters to larger volumes. Each volume configuration is engineered with distinct accuracy and precision parameters to meet the demands of quantitative analytical work where measurement reproducibility is critical.
How It Works
The TopPette-Mechanical Pipette operates on a positive displacement principle using a mechanical piston mechanism. The user sets the desired volume using a mechanical adjustment system, which positions the piston to create a precise internal volume chamber. When the plunger is depressed, it creates a vacuum that draws liquid into the tip through precise mechanical displacement.
The volume accuracy and precision are achieved through precision-machined internal components and calibrated mechanical stops. Each volume range utilizes specific internal geometries optimized for that particular measurement range, ensuring consistent performance across the specified volume span. The mechanical design eliminates electronic components, providing reliable operation in various laboratory environments.

Practical Tips
Perform gravimetric calibration verification using distilled water at room temperature on an analytical balance.
Why: Ensures measurement accuracy meets specifications and identifies drift requiring adjustment or service.
Clean external surfaces regularly and lubricate mechanical components according to manufacturer schedule.
Why: Prevents buildup of residues that can affect accuracy and extends operational life of precision mechanical parts.
Pre-wet pipette tips by aspirating and dispensing the target volume 2-3 times before actual use.
Why: Eliminates air bubbles and ensures consistent liquid film in the tip for accurate volume delivery.
Hold the pipette vertically during aspiration and maintain consistent plunger operation speed.
Why: Minimizes volume variability and ensures reproducible liquid handling technique across measurements.
Work within the upper 10-100% of the pipette's volume range for optimal accuracy performance.
Why: Mechanical pipettes typically achieve best accuracy and precision when used in their upper volume range.
If volume delivery appears inconsistent, check tip sealing and inspect internal seals for wear.
Why: Poor sealing is the most common cause of volume inaccuracy in mechanical pipette systems.
Use appropriate pipette tips rated for your specific chemical applications and replace tips between samples.
Why: Prevents cross-contamination and protects internal pipette components from chemical damage.

Background reading relevant to this product:
What accuracy and precision can I expect across the different volume ranges?
Accuracy and precision specifications vary by volume range. Specific models offer accuracy parameters such as 2.00% with precision of 1.2%, while other ranges have different performance characteristics optimized for their volume span. Consult the product datasheet for complete accuracy specifications for your required volume range.
How do I select the appropriate volume range for my application?
Choose the range that encompasses your typical working volumes, with your target volume falling in the upper 10-100% of the pipette's range for best accuracy. Consider both your minimum and maximum volume requirements when selecting the appropriate model.
What maintenance procedures are required for optimal performance?
Regular cleaning of external surfaces, periodic calibration verification using gravimetric methods, and replacement of worn internal seals as needed. Avoid autoclave sterilization of the entire unit unless specifically rated for such treatment.
Can this pipette handle organic solvents and corrosive reagents?
Compatibility depends on the internal materials and seals used in construction. Consult the chemical compatibility chart in the product documentation before use with organic solvents, acids, or other potentially damaging reagents.
How often should I perform calibration verification?
Verify calibration monthly for routine use, more frequently for critical applications, and immediately after any maintenance or if accuracy concerns arise. Use gravimetric method with distilled water at controlled temperature.
What pipette tips are compatible with this system?
The pipette is designed to work with standard pipette tips matching the volume range and tip connection design. Verify tip compatibility and proper sealing before use to ensure accurate volume delivery.
