Product Overview
A 60 mm bar is the length to reach for when a short bar only whirls a small spot at the bottom of a larger vessel. Its center ring makes it a better match for a concave floor than a convex one.

Frequently Asked Questions
Is it PTFE covered?
Yes. The white covering is PTFE, over an eight-sided body with a ring at its center.
Will it spin well in a vessel whose floor domes upward?
No. A pivot-ring bar is made for concave bottoms, and on a convex floor it has trouble holding contact and steady spin. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Sixty millimeters, eight flat sides and one ring at the middle. The shape of the flask bottom decides the rest.
