Use these filtration cartridges in your ResinTech, UNIX, Barnstead® PCS® and Vaponics® water purification systems or design a system using wall-mounting brackets and extension tubing (order separately). Permanent joint welds create a hermetic seal and improve longevity in any installation. Nonpigmented ABS plastic housing is durable and produces high-purity laboratory-grade water. Choose between the standard ARIES connection type and the versatile 3/8" hose nipple, both of which are available in a variety of filter media.
