This has been and remains to be our most popular piece of equipment, which is the reason we have so many around. The popularity comes from their ease of use, large useful temperature range and reliability. Although their function is the same all of the systems do not look the same. The exterior differences are simply because of different manufacturers and varying ages. These systems are good work horses and have been in our fleet of 20 years. These are the systems users will be encouraged to use if low temperatures are not essential for your experiment.
