Abstract
A device for dialysis of a sample includes a sample chamber formed by a gasket and dialysis membranes affixed to each side of the gasket in facing relationship. A housing supports the dialysis membranes and gasket. An air chamber causes the device to float in a generally upright position when the device is immersed in a dialysate. An access port is provided through the gasket and between the dialysis membranes. The access port is accessible from outside the housing and in communication with the sample chamber such that a dispensing end of a dispensing device can be inserted through the access port to dispense sample into the sample chamber. In one embodiment, the gasket is impermeable or essentially impermeable to the sample being dialyzed.
