FAQ
Frequently Asked Questions
Yes. It is toxic, a strong irritant to the eyes, skin, and respiratory system, and is a potential sensitiser. It must be used with appropriate personal protective equipment (PPE) and in well-ventilated areas or fume hoods.
Cross-linking refers to the chemical process where glutaraldehyde molecules form bridges or bonds between adjacent protein chains. This stabilises and rigidifies the structure, which is why it is effective for fixing biological tissues.
No. It is an industrial and laboratory chemical with significant health hazards. It is not suitable or safe for domestic use. Common household disinfectants are far safer alternatives.
Both are aldehydes used as fixatives and disinfectants. Glutaraldehyde has two aldehyde groups (dialdehyde), making it a more effective cross-linker and a more potent sterilant at lower concentrations, though it is also more expensive. Formaldehyde is faster-penetrating but a known human carcinogen.
