Canada Balsam was the mounting media used a long time ago (a bit like tree sap or rosin).
It was replaced with DPX, the current mounting media, as it went brown with age.

Specifically look out for ones with spikes rather than loops to hold bottles, test tubes etc. Also see if the spike racks are removable so that larger objects can be accommodated. The trays should also be removable to assist in cleaning, and it should work without the top tray/rack to hold larger ob...

Normality = molarity x No of H ions (for acids)
eg H2So4 18M = 36N
H3PO4 15M = 44N ?

Hi Rhonda, I don't know this model directly but I have seen a detector head. The detector must be open to the air. The voltage should be adjusted to the point where sparking just stops. Take care as the unit must use an internal voltage step up system. The voltage will typically be around 1000V per ...

When I worked for NCR ( cash registers ) they used to clean with it, it was called X222 (petrol ether).
