Eppendorf Res.3 piston spring 5mL violet 3102636001

This item is a replacement piston spring for Eppendorf Research-series manual pipettes, specified for the 5 mL (0.5–5 mL) family and color-coded violet. It is intended to be installed in the piston assembly to restore the piston return force and correct mechanical function after wear or during service; primary use cases are repair, maintenance, and parts replacement for Eppendorf Research / Research plus pipettes used in routine liquid handling.

Key Features:

• Product type: piston spring (replacement part for Eppendorf Research pipettes).
• Intended volume family: for 5 mL pistons / 0.5–5 mL pipette range (violet code).
• Color code: violet (matches Eppendorf 0.5–5 mL Research pipette color coding).

Advantages:

• Restores original piston return action and tactile performance after spring wear, supporting accurate manual pipetting when installed as a genuine replacement.
• Color coding (violet) simplifies identification and selection of the correct 0.5–5 mL service part, reducing installation errors.
• Using an OEM replacement part preserves compatibility with Eppendorf piston/cylinder assemblies and the manufacturer’s recommended serviceability practices.
