The Bioptechs, Inc. Delta T Culture Dish System is designed to simulate host conditions on the stage of your microscope and provide an optimal optical environment for microscopy. This two-step system allows you to plate your cells and observe them without having to transfer them to another structure. The system components are, the Controller, Stage Adapter, and Dishes.  Accessories for Tissue Slice, Brain Slice, and other specimens are available.

An intelligent feedback loop passes an electrical current through a thin film coating on the underside surface of the glass substrate on which the cells are grown. Heat is applied directly to the cells without the inefficiencies associated with peripheral heating by traditional culture dish warmers. Bioptechs exclusively offers opaque culture dishes which eliminates the unwanted ambient light background for fluorescence imaging.

The controller features a real-time temperature display and fast learning curve to compensate for cooling due to surface evaporation while responding to temperature changes due to perfusion. There is also an alarmed protection circuit to safeguard the cells and an internal reference for the user adjustable calibration. The standard controller has a temperature range of ambient to 50 degrees C. Extended ranges are available upon request.

Delta T dishes have 35mm O.D. and a 23mm central aperture. The peripheral region of the dish is tapered to reduce the dead-volume and the height of the dish is 6mm to allow better access for micro-injection and micromanipulation. The dishes are a hybrid of polystyrene plastic and Desag 263 glass. The outer structure of the dish is available in opaque black or clear and come with a clear 0.5mm or no.1.5 glass coverslip bottom bonded to it.  The dishes are also available in a plain glass unheated version.
