A perfusion chamber with temperature regulation.

When investigating microscopic preparations perfusion chambers allow exchange and regulation of different solutions and ensure their constant flow in the sample chamber. Temperature deviations, however, may be problematic. We describe a new chamber that contains an additional circulation system which regulates the inside temperature using an external thermostat. An integrated thermometer probe records the sample temperature, which appears on a monitor. The glass chamber, measuring 75 x 35 x 3 mm, provides good optical quality and is compatible with every type of microscope.
