This negative pressure vacuum mixer is the main device used by dental technicians to blend embedded materials (phosphate, etc.) into horizontal materials (AGAR, gypsum, etc.). It is done in a vacuum and is completely free of bubbles, thus improving the fillability of the material and the density of the model. It utilizes an external air compressor, not an internal vacuum pump, to generate the negative pressure vacuum. It comes with an air tube to connect to the user’s air compressor, which should have a minimum pressure of 0.6Mpa. Our dental mixers utilize advanced vacuum technology to remove air bubbles from investment materials, creating homogenous mixes for dental restorations.
