   • Are these compatible with the Vitrobot Mark IV?

     “Yes. The Vitrobot tweezers assembly (47000-500/505) includes the specific dovetail mount required to fit the plunger of the FEI/Thermo Fisher Vitrobot Mark IV, III, II, and I.”

   • What is the benefit of self-closing tweezers?

     “Self-closing tweezers (or reverse action) naturally hold the grid closed without applying hand pressure. This is safer for cryo grid manipulation as it prevents accidental dropping if your hand slips or gets tired.”

   • Can I use standard tweezers for AutoGrids?

     “It is not recommended. Standard tips can slip off the metal ring. AutoGrid tweezers have a "step" machined into the tip that physically interlocks with the ring, providing a secure hold for AutoGrid clipping and loading.”

   • Are the tips replaceable?

     “For the Vitrobot assembly, the entire tweezer unit is typically replaced to ensure the dovetail alignment remains precise. However, we offer high-quality DUMONT tweezers as standalone replacements for general handling.”

   • Do they rust in Liquid Nitrogen?
