This is important. If you see any problem with any of the holders, report it to the manager immediately. Otherwise, you could be the one held accountable for the damage. Several details about the holder must be checked carefully before use:
Overall shape is good, and there is not obvious damage.
Make sure there is no crack or any other damage on the O-ring. If you do see a damage, like a cut etc., ask manager to replace it for you. Check if there any dirt or fibril on the O-ring. You might want to clean it gently with alcohol and slightly re-grease it. Do not over-grease. The main function of the grease is to lubricate.
Gently secure the specimen grid on its position. Use the tool pin to open and close the clamping device.
