Product Description

Frequently Asked Questions

What is a CHEMGLASS egg-shaped PTFE stirring bar used for?

A CHEMGLASS egg-shaped PTFE stirring bar is used in laboratory mixing applications, particularly in round-bottom flasks, to provide efficient agitation of liquids. Its egg shape reduces wear on glassware and is ideal for chemical synthesis, pharmaceutical research, and biotech processes requiring inert, autoclavable components.

What are the specifications of the CHEMGLASS CG-2005-11 stirring bar?

The CHEMGLASS CG-2005-11 is a white, egg-shaped PTFE stirring bar with an overall length of 25.4 mm, a diameter of 12.7 mm, and an overall width of 12.7 mm. It is autoclavable and designed for metric lab equipment. The PTFE material provides chemical resistance and non-stick properties.

Where to buy CHEMGLASS stirring bars in worldwide?

You can order the CHEMGLASS CG-2005-11 egg-shaped stirring bar through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide locations. Contact us for availability and lead time; we source and deliver this item to your lab or facility.

How to select the right size egg-shaped stirring bar for a round-bottom flask?

Select an egg-shaped stirring bar like the CHEMGLASS CG-2005-11 (25.4 mm length, 12.7 mm diameter) so it fits loosely in the flask bottom without binding. A general rule is the bar length should be about one-third to one-half the flask diameter. PTFE bars are autoclavable and chemically inert for most lab solvents.
