Evolution Gas Measurement Apparatus, Borosilicate Glass, 250 ml

Chemglass evolution gas measurement apparatus, 250mL. Apparatus provides a convenient and accurate method for the determination of the concentration or purity of active metals and metal hydrides. Metals and metal hydrides that can be analyzed in this manner include borane-methyl sulfide complexes, borane tetrahydrofuran, sodium and lithium as dispersions in mineral oil, lithium aluminum hydride. These active metals and metal hydrides react rapidly and quantitatively with suitable hydrolytic solvents to produce hydrogen gas. Available in three capacities: 50mL, 250mL and 1000mL. All complete units supplied with a buret, a -10 to 260º thermometer, a 24/40 thermometer adapter and a leveling bulb with a 24/40 top outer and a lower detachable hose connection. The leveling bulb capacity varies with the capacity of the buret and has a hose connection of 8mm O.D. Flexible tubing is not supplied with the apparatus.
