Unguator Disposable Mixing Blade, 100-200mL. Recommended for sensitive formulations where it is crucial to maintain a closed environment after the mixing process. The disposable blades are made from an inert polymide plastic and attach directly to the appropriate titanium-hardened stainless steel Disposable Blade Shaft, sold separately. Once mixing is completed, the blade is disengaged from the shaft and remains inside the jar. Designed for use with smaller volume (15-200 ml) jars only, Disposable Mixing Blades provide excellent results with minimal clean-up.
