A new line of Circulating Baths from Polyscience provide precise temperature control for membrane filtration characterization and testing. Designed to control temperature with stabilities as precise as ±0.005°C over temperature ranges as broad as -40° to +200°C, these baths are ideal for a wide range of membrane testing system applications, including permeation testing, pressure decay testing, bubble point tests, and fouling experiments. Available in both refrigerating/heating and heat-only models, these circulators come in reservoir sizes ranging from 6 to 75 liters and with a choice of six different temperature controllers, including two with time/temperature programming capability. They incorporate many ergonomic features to make the lab more productive and efficient. They also include a swiveling control head that permits viewing of the temperature display anywhere within a 180° viewing radius, an integral lid docking system for no-mess reservoir cover storage and a corrosion and chemical resistant top plate that dampens noise and remains cooler at high temperatures.
