This fully autoclavable sandblaster dramatically enhances dental bonding by optimal micro-roughening. Major internal improvements over previous models lead to enhanced performance with a 40% reduction in abrasive use. Can be used effectively at pressures as low as 45 psi. The new nozzle is slimmer in profile, permitting greater visibility. Patented design allows the nozzle to be rotated 360° and interchanged with multiple nozzle sizes and angles.
