About This Product
Microbiology and enzyme practicals depend on cultures being kept at a set temperature, and the thermometer lets students check that value through the incubator window without opening the door. The L-shaped version keeps the bulb inside the chamber while the scale faces outward for easy reading. Schools, colleges and institutes in Saint Lucia, Haiti, Jamaica, Bahrain, Brunei and Iceland can order the Incubator Thermometers from Educational Instrument.
Frequently Asked Questions
What is the L-shaped incubator thermometer for?
The 90-degree bend keeps the bulb deep inside the incubator while the scale lies horizontally where it can be read easily.
