Are Lab Coats In Science Labs Washed And Reused?

Lab coats are a fundamental requirement in scientific laboratories as they provide indispensable protection against chemical spills, biological hazards, and other potential dangers. However, the fate of lab coats after usage varies based on several factors, such as the nature of the lab work, the materials comprising the lab coat, and the specific policies governing the lab.

Disposable lab coats

Disposable lab coats are crafted from lightweight and breathable materials like polypropylene or polyethylene. Their purpose is to be worn once and subsequently disposed of. This is particularly crucial in laboratories where scientists handle hazardous materials or biological pathogens. Disposable lab coats effectively mitigate the risk of cross-contamination and shield the wearer from exposure to harmful substances.

Reusable lab coats

Reusable lab coats are crafted from highly durable materials, such as cotton or polyester, ensuring repeated utilization. Nonetheless, it should be noted that the level of protection offered by reusable lab coats is not equivalent to that of disposable lab coats. With time, the fabric of reusable lab coats may undergo wear and tear, and the fibers may accumulate dirt and debris. Consequently, the effectiveness of the lab coat as a barrier against chemical spills and biological hazards may be compromised.

Washing reusable lab coats

When working in a laboratory where reusable lab coats are utilized, it is crucial to adhere to the specific policies and procedures for washing and disinfecting lab coats. Lab coats should be laundered separately from other garments and subjected to a hot cycle (minimum 140 degrees Fahrenheit) using a detergent that effectively eliminates grease and grime. Moreover, lab coats should undergo disinfection after each use. This can be achieved by immersing the lab coat in a bleach solution or by employing a commercial disinfectant spray.

When to use disposable vs. reusable lab coats

The selection of a suitable lab coat varies based on the nature of lab work and the materials employed. When dealing with hazardous materials or biological pathogens, it is imperative to employ disposable lab coats. For non-hazardous materials, reusable lab coats may suffice, although it is crucial to consult your lab supervisor for confirmation of acceptability.


Lab coats are a crucial component of safety gear in science laboratories. Whether opting for disposable or reusable lab coats, regular washing and disinfection are imperative. These measures are essential to safeguard oneself and colleagues from potential exposure to hazardous materials and biological pathogens.
