Globe Scientific Pipette Tips 0.5 ml Individually Sealed 96 Tips

Globe Scientific 3923S RV-Pette Pro™ 0.5 ml Dispenser Tips (Sterile, Individually Wrapped)

The Globe Scientific 3923S is a high-precision 0.5 ml dispenser tip engineered for rapid, repetitive pipetting in demanding laboratory environments. Utilizing a positive displacement principle, these tips feature an internal plunger that makes direct contact with the liquid, ensuring consistent and accurate dispensing of viscous, volatile, or high-density fluids. Manufactured in a controlled cleanroom environment from medical-grade polypropylene and polyethylene, each tip is certified sterile and free from biological contaminants. These 0.5 ml tips are individually wrapped to maintain the highest level of purity, making them ideal for serial aliquoting in molecular biology, clinical chemistry, and pharmaceutical research.

Technical Performance and Design

• Positive Displacement Accuracy: The integrated piston design eliminates the air cushion found in standard pipetting, providing high precision when handling reagents like glycerol, ethanol, or foaming detergents.

• Universal Fitment: Specifically optimized for the Globe RV-Pette Pro™ repeater, but fully compatible with most industry-standard manual and electronic repeating pipettes, including the Eppendorf® Repeater® and Brand® HandyStep®.

• Aseptic Individual Packaging: Each tip is hermetically sealed in a medical-grade pouch, preventing batch contamination and ensuring that every tip is sterile at the point of use.

• Zero Cross-Contamination: The positive displacement design prevents aerosols from entering the pipette body, protecting both the instrument and subsequent samples from carry-over contamination.

Key Benefits & Applications

• Efficient Serial Dispensing: Allows for dozens of accurate dispenses from a single aspiration, significantly reducing hand fatigue and increasing throughput for microplate filling.

• Challenging Fluid Handling: The standard choice for pipetting oils, resins, volatile solvents, and radioactive solutions where air-displacement pipettes often fail to meet accuracy specs.

• Molecular Diagnostics: The sterile and DNase/RNase-free certification makes these tips suitable for sensitive PCR, NGS library prep, and other enzymatic assays.

• Laboratory Safety: The sealed, positive-displacement format provides an extra layer of safety when handling infectious or hazardous biological samples by containing them entirely within the tip.
