the division board, it sets up the inside intermediate position department of cell culture hole, and it with cell culture hole block, the both sides of division board all are provided with the separating groove, the outer wall of division board is provided with the aperture, and the aperture size is 0.4-70um.

Preferably, the outer wall of cell culture hole upper surface is provided with cultivates the hole notch, and cultivates hole notch and cell culture hole formula structure as an organic whole.

Preferably, the cell culture wells are arranged in a 12 × 8 horizontal direction.

Preferably, the separator is made of one of polycarbonate, polyester, and polyethylene terephthalate (pet) polytetrafluoroethylene.

Preferably, all be provided with the lid socket around the cultivation porose layer, and lid socket and flat base micropore board body formula structure as an organic whole.

Preferably, the inside of lid socket is provided with the lid slot, and lid slot and lid socket formula structure as an organic whole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up cell culture hole and division board, can operate suspension cell's cultivation effectively, change the culture medium, perhaps add compound, the concentration of adjustment compound etc. because the existence of middle division board, can effectively prevent to trade the influence of liquid operation to the cell to can carry out the culture of dosing for a long time to the cell, even if change liquid many times repeatedly, also smaller to the influence of cell, be favorable to guaranteeing the quality of cytology experiment.
