Alert Signals
Propriety Name: Dri-Bath Common Name: Test Tube Incubator
Intended Use
The Thermolyne Type DB5900E Dri-Bath Test Tube Incubators are designed to provide a controlled dry heat environment for 13 mm test tubes containing in vitro diag­nostic specimens or samples for qualitative or quantitative test procedures. The operator may easily view test tube contents while incubating. (Please refer to the clinical lab­oratory method specified by the reagent manufacturer or established by medical technology for product applica­tion.) For in vitro diagnostic use.
Installation
Remove the incubator from the carton. Check the specifi­cation plate on the bottom cover plate for proper voltage and plug into a properly grounded receptacle.
Principles of Operation
The Type DB5900E Dri-Bath incubator is controlled by a precision temperature sensor and solid state electronic temperature controller. A wire wound heating element covers the under surface of the base casting providing uniform heating of the block. An anodized aluminum block drilled for 13 mm tubes is mounted on the base casting. Cutouts are made for each well and transparent plexi­glass side panels cover the contact area for easy viewing. This design provides heating of the base and sides of the test tube for uniform temperature of test tube contents.
