ConductScience 200µL pipette tips are precision-molded from medical-grade polypropylene for accurate liquid handling in research applications. These universal-fit tips are compatible with most standard micropipettes and feature high optical clarity for visual volume confirmation during critical procedures.
Each tip is manufactured sterile and certified DNase/RNase-free to prevent nucleic acid contamination in molecular biology workflows. The autoclavable polypropylene construction allows for repeated sterilization cycles when required by laboratory protocols. The non-filtered design provides unrestricted sample flow for general pipetting applications where aerosol protection is not required.
How It Works
Pipette tips function as disposable precision liquid handling interfaces that attach to micropipettes via a friction-fit mechanism. The conical geometry creates a sealed connection with the pipette shaft while the tapered orifice controls liquid dispensing accuracy through surface tension and controlled wetting properties.
The medical-grade polypropylene construction provides low-binding characteristics, minimizing sample retention and ensuring quantitative transfers. The smooth internal surface reduces turbulence during aspiration and dispensing, while the high optical clarity allows visual verification of liquid levels and detection of air bubbles that could compromise volumetric accuracy.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Grade | Medical-grade polypropylene | Standard laboratory-grade plastics with variable quality specifications | Ensures consistent performance and chemical compatibility across diverse research applications. |
| Sterility Assurance | Sterile packaging with DNase/RNase-free certification | Non-sterile tips requiring separate sterilization procedures | Eliminates pre-use sterilization steps and nucleic acid contamination risk in molecular biology workflows. |
| Optical Properties | High optical clarity for visual volume confirmation | Standard clarity tips with limited visibility of liquid levels | Enables real-time volume verification and air bubble detection for enhanced accuracy control. |
| Compatibility Range | Universal-fit design for most standard micropipettes | Manufacturer-specific fitting requirements limiting cross-platform use | Reduces inventory complexity and ensures workflow flexibility across different pipette brands. |
These tips combine medical-grade construction with universal compatibility and sterile packaging to support accurate liquid handling across diverse research applications. The DNase/RNase-free certification and high optical clarity provide additional quality assurance for molecular biology and analytical protocols.
Practical Tips
Pre-wet tips by aspirating and dispensing the target liquid several times before actual sample transfer.
Why: Eliminates surface tension effects that can cause volume inaccuracies in the first aspiration cycle.
Verify pipette-tip combination accuracy using gravimetric calibration with distilled water at room temperature.
Why: Ensures the complete liquid handling system meets accuracy specifications for your specific protocols.
Inspect tip orifice for damage or deformation before use, especially when working with viscous samples.
Why: Damaged tips can cause volume errors and compromise reproducibility in quantitative applications.
Use consistent aspiration and dispensing speeds to minimize volume variation between replicates.
Why: Controlled liquid handling technique reduces systematic errors and improves measurement precision.
Never reuse tips between different samples or reagents, even within the same experiment.
Why: Prevents cross-contamination that could compromise experimental results or create safety hazards.
If liquid retention occurs, check for proper tip sealing and consider using low-retention tips for protein solutions.
Why: Improper sealing or sample composition can cause volume losses that affect quantitative accuracy.

Background reading relevant to this product:
What is the volume accuracy and precision specification for these tips?
Consult product datasheet for specific accuracy and precision values, which depend on the calibrated micropipette used with the tips.
Are these tips compatible with electronic multichannel pipettes?
The universal-fit design is compatible with most standard micropipettes; verify shaft diameter compatibility with your specific electronic pipette model.
Can these tips be used with organic solvents and aggressive chemicals?
Medical-grade polypropylene provides good chemical resistance, but consult the chemical compatibility chart for specific solvents and exposure conditions.
How should unused sterile tips be stored to maintain sterility?
Store in original sterile packaging at room temperature in a clean, dry environment away from direct sunlight and contamination sources.
What is the maximum temperature for autoclaving these tips?
Polypropylene construction allows standard autoclave cycles; consult product specifications for maximum temperature and pressure limits.
Are these tips suitable for PCR applications?
Yes, the DNase/RNase-free certification and sterile packaging make them suitable for PCR setup and nucleic acid handling protocols.
How do these compare to filtered pipette tips?
Non-filtered tips provide unrestricted sample flow and maximum accuracy but lack aerosol barrier protection; choose based on contamination risk assessment.
