Special Projects: Custom Glass Beakers
The custom jacketed beaker pictured on the right is our latest iteration of this venerable piece of lab glass. Recently, we have produced quite a few of these large beakers, often with jackets for temperature control. People want to see....
The opening across the inside is just under 10" and measures a very shallow 50mm depth. That's a 4mm teflon stopcock drain porting out the bottom of the beaker.
"Custom" can present challenges. The requirement for such a shallow depth on this jacketed vessel meant that we would not be able to produce it our normal way. |

The success of a new technique is not a given. The challenges are several; will the strength of the vacuum be enough to support the inside while melting and fusing the glass ringseal? Will anything melt or burn up?! Can we keep everything hot enough during assembly to prevent the thermal stresses from shattering the works? You can imagine that any problem during hot glass fusion is a BIG problem and is mostly catastrophic. Not this time! Challenges are constant for glassblowers, as are the thrills....... |
