Support floatation block

A block designed to facilitate carbon film floatation from mica or graphene layer floatation from a substrate, for use as an electron microscopy sample support avoiding the destabilising effects of the air-water interface.

The block is designed to accommodate four samples (enough for one grid box), allowing for buffer exchange, either in situ using two needles under the surface on which the film is floated, or by movement to the well behind.

Supports for both negatively stained and cryogen
