[. . . ] Delta T Heated Culture Dish Cover with Perfusion Ports Instructions Description: The Bioptechs Delta T® Heated Lid w/ Perfusion is a device, which will provide a condensate free optical surface on the top of a Delta T® Dish through which specimens can be trans-illuminated on an inverted microscope. [. . . ] After the Heated Lids is warmed, it can be mounted to the Delta T® dish by applying a combination of downward and slight rotational force to the lid in such a manner to compress the o-ring seal to seat the lid on the dish. It is powered by a 2. 5-volt adjustable power supply located on the back of the Delta T®4 Controller. The voltage should be adjusted to a point where the temperature of the glass surface of the lid prevents condensation in the dish. However, It may be necessary to adjust the voltage depending on ambient conditions. An adjustment screw for this setting is provided adjacent to the Heated Lid Socket on the back of the Delta T4 controller. Alternate power supplies can be used including a DC battery or an AC adapter. Cleaning: The heating lid can be cleaned with mild laboratory soap and water, rinsed and dried. If sterilization is a concern it can be placed in an autoclave bag and autoclaved on a short cycle of about 15 minutes.
