What method can sterilize instruments in 10 seconds?

• A. Autoclave
• B. Glass bead sterilizer
• C. Hydrogen peroxide
• D. Ethylene oxide gas

Answer: (B)

A glass bead sterilizer provides rapid surface sterilization by exposing small, heat-tolerant instruments to hot glass beads for a very brief period. The beads are heated to a high temperature, and the direct contact of the instrument with the beads delivers enough dry heat in about ten seconds to kill many microorganisms on the instrument’s surface. This quick cycle makes it suitable for fast turnaround between procedures on small metal tools that can withstand brief dry-heat exposure. Other methods require longer cycles and different technologies. An autoclave uses steam under pressure and typically takes many minutes (plus drying) to complete, so it isn’t a ten-second process. Hydrogen peroxide and ethylene oxide sterilization involve specialized equipment and longer cycle times, not a ten-second turnaround.
