Globe Scientific 3922S RV-Pette Pro™ 0.2 ml Dispenser Tips (Sterile, Individually Wrapped)

The Globe Scientific 3922S is a precision-engineered 0.2 ml dispenser tip designed for high-accuracy repetitive pipetting. Part of the RV-Pette Pro™ lineup, these tips utilize a positive displacement principle, ensuring that the liquid is physically displaced by a plunger for consistent delivery regardless of fluid viscosity or density. This makes them exceptionally reliable for handling volatile solvents, viscous oils, and foaming liquids. Every tip is manufactured in a cleanroom environment from high-purity polypropylene with a polyethylene plunger. Certified sterile, non-pyrogenic, and individually sealed, the 3922S is an essential tool for clinical diagnostics, molecular biology, and pharmaceutical research where contamination-free, serial dispensing is required.

Technical Performance and Design

• Positive Displacement Technology: The integrated plunger wipes the capillary wall clean during dispensing, ensuring virtually 100% liquid recovery and eliminating the "cushion of air" that causes inaccuracies with volatile or viscous samples.

• Universal Compatibility: Designed for seamless integration with the Globe RV-Pette Pro™ repeater pipette. These tips also maintain compatibility with other industry-standard repeating pipettes, including the Eppendorf® Repeater® (M4 and Plus versions) and the Brand® HandyStep®.

• Individually Wrapped Purity: Each tip is hermetically sealed in its own medical-grade pouch, ensuring that sterility is maintained until the exact moment of use—ideal for sensitive PCR or cell culture workflows.

• Volume Precision: Specifically calibrated for a 0.2 ml total capacity, allowing for numerous sub-aliquots (depending on the pipette setting) with high coefficients of variation (CV) and accuracy.

Product Specifications

Key Benefits & Applications

• Serial Dispensing: Dramatically increases throughput when filling multiple microtubes or microplates by allowing up to 48 dispensing steps without refilling.

• Viscous & Volatile Fluids: The standard choice for pipetting reagents such as glycerol, concentrated buffers, alcohols, and radioactive isotopes where air-displacement accuracy fails.

• Contamination Prevention: Because the liquid never enters the pipette body, the risk of aerosol-based cross-contamination between samples or the instrument is completely eliminated.

• Molecular Biology: The "PCR Clean" certification ensures that these tips are safe for use in genetic amplification and other sensitive enzymatic reactions.
