NanoSoft's CryoARM c-clips are compatible with the JEOL cryoARM cartridge/autoloader system. These c-clips have been tested and work seemlessly with the cryoARM cartridges, with the same level of robustness as the OEM version, at a much better price point. They can be used many times, with similar care as the OEM JEOL version, but at this price point, you can feel more comfortable using them fewer times, reducing risk of using old, damaged clips.
