This Erlenmeyer Flask Holder lets you shake one to four Erlenmeyer flasks at a time. It will work with uncapped flasks (for gentle shaking), or you can close them with screw caps or tapered stoppers. An elastic band automatically holds the stoppers in place. One or two flask holders can be shaken at once. A locking knob secures holder in optimum positions for both loading flasks and for effective shaking. While mounted on the shaker, the holder can be rotated 180. Each holder adjusts to accommodate three 500 ml flasks, or four 125-250 ml flasks. A combination of flasks is possible as well.
Use this Flask Holder with Glas-Col's Bench-Top Shaker (item# 21200), which is an adaptable, user-friendly shaker that is capable of many hours of continuous shaking and mixing and marries reciprocating shaking and mixing with bench-top convenience.
