Eppendorf Pipette Research Plus 100 ul Single Channel Pipettor

The Eppendorf 3120000047 Research Plus Pipette is a variable volume, single-channel instrument covering the 10–100 µL range, widely regarded as one of the lightest and most ergonomic mechanical pipettes available. Part of Eppendorf's "PhysioCare Concept," this pipette is engineered to minimize hand fatigue during prolonged use by significantly reducing the weight and force required for operation. The volume display is magnified and features four digits, allowing for precise volume setting and easier readability compared to standard three-digit counters. The distinct yellow operating button provides a quick visual reference, instantly identifying it as compatible with standard 200 µL or universal yellow tips.

A standout innovation of the Research Plus line is the spring-loaded tip cone. This mechanism allows the cone to retract slightly during tip attachment, which not only lowers the force needed to create a secure seal but also ensures improved tip fit and tightness, reducing the variability often seen between different users. The pipette is constructed from Fortron organic polymer, a highly resistant material that makes the entire instrument thermal and chemical resistant. As a result, the pipette is fully autoclavable without the need for disassembly, simplifying decontamination protocols and ensuring sterility for sensitive workflows.

For advanced users, this model features a secondary adjustment option. This allows the user to temporarily recalibrate the pipette for liquids with physical properties different from water (such as viscous glycerol or volatile ethanol) without losing the original factory calibration. An adjustment opening on the body makes this process tool-free and reversible, providing flexibility for diverse laboratory applications.
