Apparatus for handling cells, embryos or oocytes

Apparatus for handling cellular entities comprises a first substrate having an array of first wells open to a first major surface of the first substrate, said first wells being adapted to hold a cellular entity, the apparatus further comprises fluidic channels open to each well. The wells are tapered to locate the cellular entity at a given location in each well, and the fluidic channels are formed on the major surface of a further substrate adapted and arranged to face a major surface of said first substrate, the further substrate being releasably secured to said first substrate.
