Pipette single test
Polypropylene pipette tips with temperature resistance from -80°C to 121°C, available in seven capacities from 10µL to 1000µL for precise liquid handling applications.
| Automation Level | manual |
Polypropylene pipette tips designed for precise liquid handling across laboratory applications requiring accurate volume transfer. Compatible with standard pipettes across seven capacity ranges from 10µL to 1000µL. Manufactured from transparent polypropylene with temperature resistance from -80°C to 121°C, enabling use in both cryogenic applications and autoclaving procedures.
Available in multiple capacities to accommodate diverse experimental protocols, from microvolume sample preparation to larger reagent transfers. Each box contains 96 tips with minimum ordering quantity of 100 boxes (9,600 tips) to support high-throughput laboratory operations.
How It Works
Pipette tips function as disposable contact surfaces that create a sealed interface between the pipette piston and the liquid being transferred. The conical geometry ensures proper fit with pipette shafts while the hydrophobic polypropylene surface minimizes liquid retention and wetting effects that could compromise volume accuracy.
During aspiration, the tip creates a sealed chamber that allows controlled vacuum generation by the pipette's piston mechanism. The transparent material enables visual confirmation of liquid uptake and proper sealing. Temperature resistance properties allow the tips to maintain dimensional stability during thermal cycling procedures and autoclaving sterilization.
Volume capacity matching between tip and pipette ensures optimal performance within the specified range. The polypropylene composition provides chemical compatibility with most aqueous solutions, organic solvents, and biological fluids while preventing sample carry-over between transfers.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Temperature Range | -80°C to 121°C operational range | Standard tips often limited to 80-100°C maximum | Enables both cryogenic sample handling and high-temperature sterilization in the same tip inventory |
| Capacity Options | Seven discrete capacities from 10µL to 1000µL | Basic sets often offer 3-4 standard volumes | Provides optimal pipette performance across wider range of experimental volumes |
| Material Specification | Transparent polypropylene construction | Materials vary with some offering colored or opaque options | Allows visual confirmation of liquid uptake and bubble detection for improved accuracy |
| Packaging Format | 96 tips per box in organized array | Varies by model with different box sizes and arrangements | Matches microplate format for convenient dispensing and reduces packaging waste per tip |
| Minimum Order Quantity | 100 boxes (9,600 tips) minimum order | Order quantities vary significantly by supplier | Provides cost efficiency for high-throughput laboratories while ensuring adequate inventory |
These tips provide broad temperature compatibility and comprehensive capacity range in a standardized packaging format. The polypropylene construction offers good chemical resistance while maintaining transparency for visual liquid confirmation during pipetting operations.
Practical Tips
Pre-wet tips with sample solution when working with viscous or volatile liquids to improve accuracy.
Why: Reduces surface tension effects and vapor loss that can cause volume measurement errors
Verify pipette-tip accuracy using gravimetric method with distilled water at 20°C monthly.
Why: Environmental conditions and tip lot variations can affect measurement precision over time
Inspect pipette shaft for nicks or deformation that could prevent proper tip sealing.
Why: Damaged shafts cause air leaks leading to volume inaccuracy and tip ejection problems
Use barrier tips when handling infectious or volatile materials to prevent pipette contamination.
Why: Standard tips do not prevent aerosol entry into pipette shaft during rapid aspiration or volatile sample handling
Replace tips between each sample transfer to prevent cross-contamination and carryover effects.
Why: Even trace amounts of previous samples can significantly impact analytical results in sensitive assays
If tips fall off during use, check that tip capacity matches pipette model and volume setting.
Why: Mismatched tip-pipette combinations create poor sealing and inadequate retention force
Allow autoclaved tips to cool completely and equilibrate to room temperature before use.
Why: Temperature differences can create condensation and affect volume accuracy during liquid handling
Rotate tip box inventory using first-in-first-out system to prevent UV degradation from extended storage.
Why: Prolonged exposure to laboratory lighting can cause polypropylene degradation and dimensional changes

Background reading relevant to this product:
What is the volume accuracy specification for these tips?
Volume accuracy depends on the pipette-tip combination and proper technique. Consult your pipette's specifications and perform verification using gravimetric methods with distilled water at room temperature.
Can these tips be autoclaved multiple times?
Tips are designed for single use only. While they can withstand 121°C autoclaving for sterilization, repeated thermal cycling may affect dimensional stability and sealing properties.
Are these tips compatible with electronic pipettes?
Yes, the universal design fits standard pipette shafts from major manufacturers including both manual and electronic pipette systems, provided the capacity range matches.
What is the chemical compatibility range?
Polypropylene construction provides compatibility with most aqueous solutions, alcohols, and mild acids/bases. Avoid strong oxidizing agents and chlorinated solvents that may cause stress cracking.
How should tips be stored to maintain quality?
Store in original packaging in clean, dry conditions away from direct UV light and temperature extremes. Avoid storage near volatile chemicals that could cause contamination.
What causes tip ejection problems?
Common causes include improper tip seating, using wrong capacity tips, or pipette shaft wear. Ensure firm, even insertion and check pipette shaft condition regularly.
Can these tips be used for organic solvents?
Polypropylene provides good resistance to most organic solvents, but compatibility should be verified for specific chemicals, especially at elevated temperatures or extended contact times.
