Handy device for safely and easily breaking the tips of glass sorbent tubes.
Works almost like a pencil sharpener. The end of the glass tube is inserted (like a pencil) and rotated. Blades score the side of the glass tip. Pull slightly to one side and the glass tip is evenly and cleanly cut off.
The broken tips are retained in the body of the device. When required the unit can be opened and the broken glass tips safely disposed.
Really handy device to have in the kit.
