Experimental apparatus for biochip

An experimental apparatus for a biochip, comprising:

• an enclosure within which a chamber configured to hold the biochip and a solution is disposed, wherein the enclosure is provided with an observation area, for observing a reaction process of the biochip and the solution in the chamber during an experiment,
• the enclosure comprises:
• a first pressing block, and
• a second pressing block opposing the first pressing block,
• wherein a side of the first pressing block facing the second pressing block is provided with a first reaction groove,
• a side of the second pressing block facing the first pressing block is provided with a second reaction groove,
• the first pressing block and the second pressing block are detachable and can be fixed together, and
• the first reaction groove and the second reaction groove encircle to form the chamber,
• wherein the experimental apparatus further comprises:
• a connecting member, one end of which penetrates through the first pressing block and the second pressing block, and the other end of which is provided with a limiting part;
• and
• a spring and a locking member, wherein the spring is sleeved on the connecting member, the locking member is fixed to the one end of the connecting member, and the spring presses against the first pressing block and the second pressing block to make the first pressing block and the second pressing block fixed together.
