• Round, cylindrical shape provides better centering and creates less turbulence than a multisided shape
• Heat-resistant glass casing is nonporous and nonabsorbent, and it can resist temperatures up to 525 degree Fahrenheit (274 degree Celsius)
• Smooth surface provides quicker cleanup and less risk of cross-contamination than bars with pivot rings and allows the bar to spin on the bottom of the container to disperse light sediment and air bubbles
• Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt
• Casing material meets the U.S. Pharmacopoeia specifications for Type I borosilicate glass
