All Stainless Steel, Small Size Blending Assembly, Order No. 8712. Stainless Steel Blending Assemblies are for use with highly corrosive sample materials or where metal ion contamination adversely affects sample preparations. All metal surfaces are of stainless steel. The blending assembly washers are Teflon®. The bearing is pure carbon. In order to minimize leakage of sample solution through the drive shaft/bearing interface we have added a nitrile seal below the bearing cap. Positive pressures to 32 psi may be held for extended periods thus allowing the introduction of controlled atmospheres into the container. These sealed assemblies may be used in all Eberbach and Waring containers.
