OBJECTIVE HEATER 

The OHXX Objective Heater can be used with many oil and water type microscope objectives to prevent thermal transfer between temperature controlled specimens and the objective.  The temperature of the objective is very tightly and accurately controlled with the TC-500 Temperature Controller over the range of 30 to 50°C.

Objective diameters can vary over a rather wide range of values so the table below may be used as a guide to select the proper warming ring when ordering.  Due to constantly changing manufacturing specifications from the microscope companies and the variety of objectives available, it is advisable to contact our sales staff for assistance in choosing the correct warming ring.
