Measuring and mixing device for automatic mixing of high-quality egger duplicating silicones. The optimized feed pump and the disposable static mixing canulas (S 50) that can be exchanged easily ensure bubble-free and homogenic mixing of silicone components and therefore minimizing material consumption. The foot switch (included in delivery) makes the device easy to operate. Transparent refillable containers (material reservoirs) are also included. They can be refilled with silicone at any time. Alternatively the material refill containers can also be to attached directly to the device. Please order quick-change devices separately.
