The Dispermill Vacuum dissolver is developed to enable a dispersion process in a closed system under vacuum. The system prevents the formation of air bubbles in your viscous product during mixing or dissolving whether you are producing sealants, glues, gels or colourants. The vacuum dissolver includes a lid that is made of high-quality aluminium, a vacuum gauge and vacuum valve. The lid contains one porthole for the product inlet and two inspection windows to monitor the dispersion process. If desired, the lid can be supplied with LED lighting.
