Special Projects: Custom Mixing Bottles

< PrevNext >

Pictured here is a project for a client working on heat treating a catalyst powder. They had procured a rotating oven that utilized an off-the-shelf borosilicate bottle, which was mounted horizontally and captured by spring-loaded stainless steel ends sized to the bottle. Mixing occurs as the furnace rotated the shafts with a slow, circa 300 degree back-and-forth oscillation. We were asked to maintain the geometry of the bottle ends, but provide a larger volume within the constraints of this oven.

The client writes;
"We were using a standard 1 liter reagent bottle to process powders in a rotary tube furnace and needed to make larger batches, but were constrained to a fixed bottle height by the furnace itself. A larger diameter was possible but alas, not available off the shelf.
A&C had done custom glasswork for me in the past, and I was sure they could handle this. A brief conversation with Tom Adams and a few pictures were enough to finalize a design that included internal baffles for better mixing.
The bottles were received as expected and are working beautifully.
Thank you!"
