Our Basic Water Jacket Incubators are designed and manufactured to accommodate tight budgets, while maintaining the fundamental need of quality and precision. These units have PID microprocessor controllers, a heated outer door and a tempered-glass inner door. They provide exceptional temperature uniformity, while minimizing cold spots that lead to condensation and ultimately, contamination. Although they do not have a humidity display, the extremely stable temperature environment maintains constant humidity through evaporation at 95%. Double wall construction reduces these unit's footprint, so they fit in tight spaces as well as tight budgets.
