Product Description
One tip-over can destroy a graduated cylinder, and replacements add up quickly. This yellow plastic bumper ring absorbs the impact when a cylinder falls, helping protect the glass from cracking or shattering. It is an easy way to extend the life of glass cylinders in any lab.
This listing is for Kimble catalog number 20100-4: Plastic Bumper for Graduated Cylinders, Size 4, Case of 6. The ring is molded from low-density polyethylene and slides onto the cylinder body, where its position can be adjusted so it does not touch the receiving vessel while pouring. If a ring loosens after long use, a short soak in 90 C water returns it to its original shape. This size 4 bumper is supplied in packs of six. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.

- Impact protection – Cushions the cylinder if it tips or falls.
- Adjustable position – Slide the ring to clear the receiver when pouring.
