✨ Glutaraldehyde is a powerful chemical sterilant used for heat-sensitive medical instruments that cannot withstand autoclaving. Instruments like laparoscopic tools are delicate and require cold sterilization to maintain their structure and function. Beds and general instruments like forceps or scissors are usually cleaned by other standard methods, not glutaraldehyde.
