a Photographs of showing the slight difference in structure of the original McmB and the patented Quasi Vivo^® chamber (i) McmB (ii) Quasi Vivo^®500. b Quasi Vivo^®500 chamber for submerged cultures. c Quasi Vivo^®600 chamber, compatible with commercially available Transwells^® for air liquid interface applicattions, and also Millipore standing inserts when secured by an ‘O’ ring for liquid–liquid barrier applications. d Quasi Vivo^®900 for submerged cultures. The chambers have an optically transparent window at the base of the chamber to allow live cell imaging, and the trays are made of acrylic to help reduce non-specific binding of compounds. e Quasi Vivo^® system with reservoir, tubing and bioreactor
