If you think inflation is bad for consumer items, it is horrible for scientific supplies (and I am speaking from personal experience). I am sure that Blackstone uses extremely pure solvents, acids, water, and other chemicals for the preparation of samples, and they are not "inexpensive" to begin with. Then there is the cost of the high purity argon for their inductively coupled plasma instrument, as well as other consumables for their instrumentation. Even if there are "aftermarket" consumables available (seals, tubing for sample introduction, sample vials, etc.) they are still out of sight price wise.
Supplying and operating a chemistry or medical laboratory is extremely expensive, and that is before they attempt to attain or maintain any laboratory certifications or accreditations which also drive up the operational costs in order to maintain all the records that are necessary in order to maintain their certifications and accreditations. I'm glad I do not have those headaches any more!
