I want to do a lab activity using a small immersion heater and a beaker of
water. However, our beakers all have the usual sloped tops with a spout.
The clip on the immersion heater is meant for a coffee cup with straight
sides, and does not secure well to the beaker. It will fit on a tall
graduated cylinder, but then it is difficult to mix the water to get a
good temperature readings.
So I am looking for a straight sided beaker (graduated if available) to do
this experiment. I searched unsuccessfully on the interned, but only found
straight sided plastic beakers and jars. Nothing made of glass and
graduated.
Does anybody know of a source/company for what I need? Thanks!
