A sealed ampoule of pressurized supercritical liquid Boron Trichloride. Purity is 99.5%+. This amazing sample will phase change when heated to 178.7°C. Let it cool down below 178.7°C and it will condense back into the liquid phase again. This is truly a amazing sample! It is not recommended to heat these ampoules to the critical temp because they could burst. This fits perfectly inside the included 1 dram vial for display.
