LEWATIT® UltraPure 1297 MD

Lewatit® UltraPure 1297 MD is a less separable ready-to-use mixed bed comprising a gel type strongly acidic cation exchange resin (SAC) and a gel type, strongly basic anion exchange resin (SBA, type I), individually with a monodispersed bead size distribution (uniform particles) based on a styrene-divinylbenzene copolymer for the use in working/regenerable and polishing/non-regenerable systems for the production of ultra pure water.

The monodisperse beads are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity, and the very low content of fines also results in a low pressure drop compared to ion exchange resins with heterodisperse bead size distribution.

Lewatit® UltraPure 1297 MD is correspondingly adjusted to the total capacity of the individual components to
an equivalent ratio of 1:1. The smaller bead size of the SAC contributes to better mixing properties.

Lewatit® UltraPure 1297 MD is highly regenerated and specially cleaned for meeting the specifications of the semiconductor industry.
