Harborlite® Perlite filter aid
- High purity pharmaceutical grade perlite
- Solid/liquid separation
- Produced in accordance with cGMP manufacturing practices
Harborlite® pharmaceutical-grade filter media such as our MP² Harbolite grade are the media of choice for replacing food-grade Harborlite® perlite filter aid.
Harbolite® media is produced at Imerys’ stand-alone, state-of-the-art Lompoc plant in California, US according to a patented manufacturing process. The process generates a media that surpasses conventional diatomite filter aids in terms of purity, performance and finished product consistency.
With the exception of the acid washing purification step, the MP2 Harborlite® perlite manufacturing process is similar to that of conventional Harborlite® perlite filter aid minimizing differences in filtration processes.
MP2 Harborlite media is intended for solid-liquid separation in conjunction with a pressure or vacuum filtration system. MP2 Harborlite media is available in a wide range of permeabilities.
MP2 Harborlite meets the following cGMP requirements:
- Regulatory support
- Compendial standards
- Manufacturing and process control
