High-capacity polypropylene pipette tips designed for macro-volume liquid handling in research and clinical laboratory applications. These 5mL tips are manufactured from medical-grade polypropylene and undergo gamma sterilization to ensure contamination-free sample transfers. Each tip is certified DNase and RNase free, making them suitable for molecular biology applications where nucleic acid integrity is critical.
The non-filtered design provides unrestricted liquid flow for viscous samples and rapid dispensing applications. The universal fit accommodates most macro pipette systems, while the autoclavable construction allows for laboratory sterilization protocols when required. These tips are packaged in sterile, convenient dispenser boxes to maintain sterility until use.
How It Works
These pipette tips function through precise volumetric displacement when used with compatible macro pipettes. The tip creates a sealed interface with the pipette shaft, allowing controlled aspiration and dispensing through piston-driven air displacement. The medical-grade polypropylene construction provides chemical resistance and dimensional stability across typical laboratory temperature ranges.
The non-filtered design eliminates flow restriction, enabling rapid liquid transfer and compatibility with viscous samples that might clog filtered alternatives. The smooth internal surface minimizes sample retention and ensures accurate volume delivery. Gamma sterilization provides sterility assurance level (SAL) of 10^-6, while DNase and RNase treatment removes nuclease contamination that could degrade nucleic acid samples.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Sterilization Method | Gamma sterilization with SAL 10^-6 | Some alternatives use ETO sterilization or non-sterile packaging | Gamma sterilization provides superior sterility assurance without chemical residues that could affect sensitive assays. |
| Nuclease Treatment | Certified DNase and RNase free | Basic models may lack nuclease-free certification | Essential for molecular biology applications where nucleic acid integrity must be preserved. |
| Material Grade | Medical-grade polypropylene | Standard laboratory-grade plastics in economy options | Medical-grade material ensures biocompatibility and reduces leachables in sensitive applications. |
| Filter Design | Non-filtered for unrestricted flow | Many competitors offer only filtered versions | Enables handling of viscous samples and faster dispensing without flow restrictions. |
These tips combine medical-grade construction with gamma sterilization and nuclease-free certification, making them suitable for demanding molecular biology and clinical applications. The non-filtered design provides versatility for both routine and viscous sample handling.
Practical Tips
Pre-wet tips with sample solution when working with viscous or surface-tension-sensitive liquids.
Why: Reduces sample retention and improves volume accuracy by establishing surface wetting.
Store opened tip boxes in clean, dry environments and reseal when not in use.
Why: Maintains sterility and prevents contamination during extended use periods.
Use controlled, steady aspiration rates to minimize bubble formation with volatile solvents.
Why: Prevents volume errors and sample loss due to vapor bubbles in the tip.
Dispose of contaminated tips according to biohazard waste protocols.
Why: Prevents cross-contamination and ensures compliance with laboratory safety regulations.
Verify tip-pipette seal integrity before critical volume transfers.
Why: Incomplete sealing can cause volume inaccuracy and sample loss during aspiration.
If liquid retention is observed, check for tip damage or improper pipette calibration.
Why: Damaged tips or miscalibrated pipettes can cause systematic volume errors.

Background reading relevant to this product:
What is the sterility assurance level for these tips?
The gamma sterilization process provides a sterility assurance level (SAL) of 10^-6, meeting pharmaceutical and clinical laboratory requirements.
Can these tips be autoclaved for additional sterilization?
Yes, the medical-grade polypropylene construction is autoclavable, allowing laboratory sterilization when extended sterility maintenance is required.
Are these tips compatible with viscous samples?
The non-filtered design eliminates flow restriction, making them suitable for viscous samples that might clog filtered alternatives.
What nuclease contamination testing is performed?
Each lot is certified DNase and RNase free through enzymatic activity testing to ensure nucleic acid sample integrity.
Do these tips fit all macro pipette brands?
The universal fit design accommodates most standard macro pipette systems, though compatibility should be verified with specific pipette models.
What is the recommended storage condition?
Store in original packaging at room temperature in a clean, dry environment to maintain sterility until use.
How should used tips be disposed of?
Follow institutional biohazard waste protocols, as contaminated tips may require autoclave decontamination before disposal.
