Purolite MB400IND (1 Lb) Color-Changing Mixed Bed Resin
MB400IND Color-Changing Deionization Resin (1 Lb)
High-performance mixed bed resin with visual exhaustion indicator for ultra-pure water production
The Purolite MB400IND is a premium mixed bed deionization resin that removes total dissolved solids for laboratory-grade water purity. This 1 lb container contains a balanced 1:1 volumetric mix of strong acid cation and strong base anion resin in spherical bead form. Resin shifts from blue/black to orange when exhausted, providing a clear visual replacement indicator.
Why MB400IND Stands Out
Visual Exhaustion Indicator
Resin starts blue/black and turns orange when spent, eliminating guesswork on replacement timing
Balanced Ion Exchange
1:1 cation to anion ratio ensures complete removal of both positive and negative ions
Ultra-Pure Output
Reduces TDS to near-zero levels for lab-grade, spot-free, or aquarium-ready water
Refillable Cartridge Ready
1 lb size is ideal for refilling standard DI filter housings and portable cartridges
Purolite A4146 Blend
Premium-grade mixed bed resin from a trusted industrial water treatment manufacturer
Spherical Bead Form
Uniform bead structure provides consistent flow rates and maximum surface contact
Where MB400IND Fits
The Purolite MB400IND is compatible with refillable DI cartridges, mixed bed housings, and polishing stages in RO/DI systems. Commonly used in aquarium water preparation, laboratory water purification, spot-free car rinse systems, and window cleaning applications. Works downstream of reverse osmosis membranes to achieve 0 ppm TDS. Monitor output with a TDS meter and replace resin when color shifts to orange or conductivity rises above acceptable levels. For bulk applications, see the 44 lb container option.
Purolite MB400IND delivers reliable TDS reduction with a built-in visual indicator, trusted by professionals who need consistent ultra-pure water.
