In this configuration, every time you run an experiment, you must place the Fine Gauge Thermocouple
(thin green wire) into a Petri dish or well adjacent to your sample (from here on this will be referred to as
Reference Well). Fill the Reference Well with distilled water to a level allowing full immersion of the fine gauge
thermocouple (see Figure 16). When possible close the petri with its own plastic lid (or with SENSOR LID, see
Tip
below) and place it in the appropriate holder. Using a Reference Well in close proximity to your Experimental Well
provides active Sample Feedback Temperature Control. This ensures that your sample will be within 0.1°C from
the temperature set point regardless from room temperature variations.

Tip
►
It is recommended using
an
Okolab SENSOR LID (available for purchase) to secure the Fine Gauge
Thermocouple in place in the Reference Well during calibration or operation in Sample Feedback Mode (see
Figure 17).
Sensor lids are available for the following: 35 mm, 60 mm Petri-dish, chamber slide and chambered cover
glass. Sensor Lids are ordered separately using the codes in following table.
