Don't you just love the way they used to store chemicals back in the day when men where men and women were women? We use a fair bit of Rose Bengal as a triplet sensitiser for the photochemical synthesis of 1,2-dioxines from dienes and oxygen. At the moment we are using some top-quality Rose Bengal from the world renowned chemical supplier Gurr:
Chemicals just don't come in containers like this anymore. If Sherlock Holmes ever used Rose Bengal he would most certainly have been a Gurr-man. Unfortunately, I haven't been able to get a new catalogue from George T. Gurr. I did however find this add for his products in Journal of Physiology (March 1953, Vol. 119, No. 4):
I wonder what happened to goode olde George and his microscopical reagents. D!
A student once told me he was looking for Bengal Rose, which I assume is an Asian lady of somewhat dubious reputation :-)
ReplyDeleteyo, i have two of these acridine orange and malachite green.. i found it somewhere in very old stuffs- what is this things? looks like a paint from minerals? do i must add water and then paint with it?
ReplyDeleteI wouldn't use Acridine Orange as paint - it is used for staining DNA, and is a known MUTAGEN.
