This is a set of new Whip Mix 300ml bowls (#4452) with one new paddle assembly (#4477) and drive nut (#6578). These were bought by a prosthodontist for his dental lab but he retired recently and is selling off his stock.
The Whip Mix Vac-U-Mixer allows thorough spatulating of dental stones,
plasters, die materials, investments and alginates under vacuum to
produce smooth, dense, detailed casts or impressions. Every Vac-U-Mixer
size can be driven by both the Combination Unit or the Vacuum Power
Mixer Plus.
