ConductScience Pipette Tips 1250uL are extended-length pipette tips designed for deep-well plate access and high-volume liquid handling applications. Manufactured from medical-grade polypropylene (PP), these universal-fit tips accommodate standard micropipettes across multiple manufacturers while maintaining sterile conditions for critical applications.
The extended length design enables precise liquid handling in deep-well plates, microtubes, and tall vessels commonly used in genomics, protein purification, and analytical chemistry workflows. Each tip is manufactured DNase/RNase free and arrives sterile, eliminating nuclease contamination risks in molecular biology applications. The autoclavable construction allows for re-sterilization protocols when required by specific laboratory procedures.
How It Works
Pipette tips function through precise volumetric displacement, creating a sealed interface between the micropipette and the liquid sample. The extended-length design provides additional reach for accessing samples in deep-well plates (typically 43-45mm deep) and tall vessels without compromising accuracy or introducing contamination risks.
The medical-grade polypropylene construction offers chemical compatibility with aqueous solutions, mild organic solvents, and biological buffers while maintaining dimensional stability across temperature ranges. The hydrophobic surface properties minimize liquid retention and sample carryover between transfers. Universal-fit geometry ensures compatibility with standard micropipette manufacturers through standardized cone dimensions and sealing surfaces.
Sterile packaging and DNase/RNase-free manufacturing eliminate nuclease contamination sources that could degrade DNA and RNA samples. The autoclavable material allows for additional sterilization cycles when protocols require enhanced sterility assurance or when tips are reused in specific applications.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Tip Length | Extended length for deep-well plate access | Standard length tips require specialized long-reach pipettes for deep-well access | Enables use of standard micropipettes with deep-well plates, reducing equipment requirements and costs |
| Sterility Assurance | Sterile packaged and DNase/RNase free | Basic tips may require separate sterilization or lack nuclease-free certification | Ready for immediate use in molecular biology applications without additional processing steps |
| Volume Capacity | 1250µL maximum volume | Standard tips often limited to 1000µL or require larger bore designs | Accommodates high-volume liquid handling while maintaining precision for analytical workflows |
| Universal Compatibility | Universal-fit geometry for standard micropipettes | Proprietary tip designs limit pipette compatibility options | Reduces inventory complexity and ensures compatibility across multiple pipette brands in the laboratory |
This product combines extended length access with sterile, nuclease-free specifications in a universal-fit design. The 1250µL capacity and medical-grade construction provide versatility across molecular biology, analytical chemistry, and pharmaceutical applications.
Practical Tips
Pre-wet tips when working with viscous solutions or samples containing proteins to improve accuracy and reduce carryover.
Why: Reduces surface tension effects and ensures consistent liquid delivery in challenging sample matrices.
Inspect tip seals visually before each use and replace immediately if gaps or deformation are observed.
Why: Compromised seals lead to inaccurate volumes and potential contamination between samples.
Handle sterile tips only with clean gloves or sterile instruments to maintain aseptic conditions.
Why: Manual contact introduces contamination that defeats the sterile packaging and DNase/RNase-free manufacturing.
Verify pipette-tip combination accuracy using gravimetric testing when changing tip lots or after extended storage.
Why: Ensures volume delivery meets specifications and identifies any compatibility issues between pipette and tip batches.
Use consistent tip attachment technique with firm, straight pressure to achieve reproducible sealing.
Why: Variable sealing affects volume accuracy and precision, leading to inconsistent experimental results.
If liquid retention occurs in the tip after dispensing, check for electrostatic buildup or sample composition effects.
Why: High salt concentrations and charged molecules can cause abnormal liquid behavior that affects volume delivery.

Background reading relevant to this product:
What is the maximum volume accuracy for these extended-length tips?
Volume accuracy depends on the micropipette used. These tips maintain the accuracy specifications of the compatible pipette when properly sealed. Consult your micropipette specifications for accuracy tolerances at 1250µL volume.
Are these tips compatible with organic solvents used in analytical chemistry?
Medical-grade polypropylene offers compatibility with mild organic solvents and common analytical reagents. For specific solvent compatibility, consult the chemical resistance chart in the product datasheet.
Can these tips be autoclaved multiple times without degradation?
Yes, the polypropylene construction permits multiple autoclave cycles. However, repeated sterilization may affect tip geometry and sealing properties. Monitor tip condition and replace when dimensional changes occur.
What deep-well plate formats are accessible with these extended tips?
The extended length accommodates standard deep-well plates with depths up to approximately 43-45mm, including most 96-well and 384-well deep-well formats used in genomics and analytical applications.
How do I verify sterility maintenance during use?
Open packages aseptically and use sterile technique throughout handling. Once opened, maintain sterile conditions through laminar flow environment or sterile work area protocols.
What is the shelf life for these sterile tips?
Consult package labeling for expiration date. Store in original packaging at room temperature in dry conditions to maintain sterility and material properties.
