Product Description

Our bell jars with round bottoms and ground edges are designed for both professional laboratory use and high-visibility display. Constructed from clear borosilicate glass, these vessels offer excellent thermal stability, chemical durability, and mechanical strength. The edge grinding ensures a perfect seal on vacuum plates or display bases, facilitating safe and effective use in sensitive environments.

These bell jars excel as protective covers for delicate instruments or specimens, as reaction chambers in vacuum or controlled atmosphere experiments, and for stunning scientific or museum displays. The range covers various heights and diameters to suit botanical displays, scientific demonstrations, or industrial laboratory needs.
