An innovation only made by TPP is this unique tissue culture flat tube:
opimised growth area, sloped and flattened upper side for reduced refraction, form of tube to fit a standard 50 ml adapter, PTFE filter screw cap with 22 µm pore size.
Thanks to the special screw cap, the tube cannot roll away, therefore regaining a previous position is guaranteed. The tube is treated for culture growth over a length of 50 mm. |
