Complete replacement tweezers assembly for the FEI Vitrobot Mark IV-I.

Includes ultra fine points DUMONT #5 tweezers mounted on dovetail. Available with either a standard slide-clamp (#47000-500) or self-closing tweezer handle (#47000-505).

The new self-closing Vitrobot tweezer enables one-handed operation when picking-up/releasing a grid and eliminating the often frustrating sliding clamp that requires a 2nd hand to lock the tweezers closed. The self-closing tweezers hold the grid securely in their resting state and release when applying a small amount of pressure.
