Extremely concentric UltraCenter Precision tapered upper and lower shaft assembly provides more accurate spin without significant wobble. They were specifically designed to be used in concert with QLA AccuCenter™ brackets and UltraCenter™ vessels. The two-piece basket/paddle/cylinder shafts connect well above the mixing sample to prevent potential contamination. Constructed of highly bend-resistant 316 stainless steel and electropolished for smoothness and corrosion resistance.

These shafts are in compliance with the current USP and ASTM standards.
