As a temporary cooling medium, methyl butane is employed in laboratories. A such setup would include submerging a tissue sample in liquid nitrogen and then submerging it in methyl butane.

What is potassium hydroxide ?

An odorless, white or slightly yellow, flaky or lumpy material, potassium oxide is frequently seen in a water solution. As an electrolyte in alkaline batteries, in soap production, for electroplating, lithography, and paint and varnish removers, among other things.

Hb - CH₂ He
