For improved productivity with the Vitrobot.
These reverse-action cryo-tweezers work with all generations of the FEI Vitrobot and offer multiple features that make the sample preparation process more dependable and effortless for the user. Experienced sample preparation experts will find it smooths your workflow. Beginners will lose fewer grids and find greater success with imaging.
Modified Reverse-Action Tweezers: Standard Vitrobot plunging tweezers are positive-action and require the manipulation of an O-ring to grab and release delicate TEM grids. These modified reverse-action tweezers hold grids securely and require just a small pinch to release into the grid box. They are also narrower than typical reverse-action tweezers, allowing them to easily fit within the Vitrobot blotting arms without interfering with the blot.
Spring-Loaded Plunge Clamp: When pinched open, the clamp is easy to attach to, and remove from, the plunge arm. When closed in its natural state, the clamp attaches securely to the dovetail at the end of the plunge arm. The self-centering clamp aligns the tweezers axis with the axis of the plunger rod to ensure that it plunges safely through to the liquid ethane.
