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.
