MicroGrippers™ SPINE

Each box contains 20 MicroGripper™ Mounts precision-attached to nonmagnetic SPINE standard pins.

MicroGripper™ Mounts provide a new approach to retrieving and mounting crystals for room and low temperature measurements.

With all conventional mounts, protein and virus crystals are held in contact with the mount by liquid capillary forces at room temperature, and by frozen liquid at cryogenic temperatures. "Dry" crystals, which give the lowest possible background scatter, tend to fall off the mount.

With a MicroGripper™ Mount, you simply push the mount down onto your crystal. Its tiny, flexible, soft fingers then gently grab your crystal without damaging it (yes, even for protein and virus crystals), firmly holding your crystal in place.

MicroGrippers™ are ideal for data collection at and near room temperature. Because the crystal is gripped, viscous oils are no longer needed to prevent crystal slippage during rotations. Crystals can be mounted at home and shipped to the synchrotron at room temperature.

Use MicroGrippers™ with MiTeGen's MicroRT™ system for easy and foolproof room-temperature data collection. For the lowest background scatter possible, wick away all surrounding liquid before gripping your crystal, and then rehydrate it within the MicroRT tube by injecting a small amount of mother liquor down toward the sealed end of the tube.

MicroGrippers are also well suited for thin plates and rods. Slip them under your crystal, and their soft, flexible fingers will provide very gentle support for the most fragile samples.

For all sizes, the distance from the pin base to the center of the crystal aperture is precisely 18.5 mm and compatible with the SPINE standard. The length tolerance of the pins is 0.3 mm only.
They are compatible with all standard X-ray hardware, and can be inserted in 0.7 mm mechanical pencils or micromanipulators for easy handling.

Nonsaleable to USA and Japan! Please contact MiTeGen for distributor information.


Please note: Other pin lengths, i.e. L11, L19 and L25, will be available upon request but may have significant lead times.
