The operator sets the door to the normally open state in the access control software.
The door open button is stuck and is always pressed.
The voltage is not enough, or there is no voltage (for example, the line is broken, or the power is broken, etc.).
The magnetic piece is too far away from the lock head or the door is not closed. The magnetic piece and the lock head do not correspond to each other vertically, but an offset is generated and the lock head is not sensed.
The electric lock is set to delay, the delay time is not over, and the lock will not come down. The delay of the electric plug lock can be set to 0-9 seconds, generally no delay is set, and the delay is 0 seconds.
The electric lock is broken.
There are several reasons why the electric plug lock cannot be locked:
The operator set the door to the normally closed state in the access control software.
The lock may be stuck, for example: dust in the lock body, or defective in the mechanical design process. (This situation is rather harsh, but generally it does not occur. Please note that the electric lock should not be installed on the ground. It should be installed on the top of the door and it is not easy to get into the ash. Choose a good electric lock with good brand reputation.)
Yongyue cryo vials are made of medical grade polypropylene (PP) and have no endotoxin. They are disposable laboratory consumables specially used for storing biological samples.
The anti-slip texture of the cap and body is easy to screw cap.
The tube cap has an O-ring built-in gasket to prevent liquid leakage.
The cryo tube is suitable for ultra-low temperature refrigerators, and the tolerance temperature is -86~121 °C, and it can be repeatedly frozen and thawed.
In the gaseous state of liquid nitrogen, it can withstand low temperature to -167 ℃.
According to different requirements, there are ordinary grade and PCR grade. PCR grade products are free of DNase, RNase, endotoxin and foreign DNA. Sterilized by gamma irradiation, sterile.
