What are Formaldehyde Uses in Laboratories?
Formaldehyde’s diverse applications make it a cornerstone chemical in laboratory science, contributing significantly to research advancements across biology, medicine, and chemistry. In laboratories, formaldehyde is considered a versatile chemical due to its various uses. Formaldehyde is a versatile chemical compound widely used in various laboratory settings due to its preservative and disinfectant properties. For scientific purposes, this colorless, pungent-smelling gas is typically used in its aqueous solution form, known as formalin.
Some of the most common formaldehyde uses in laboratory settings include the following:
- Tissue Preservation and Fixation: Formaldehyde is widely employed in histology and pathology laboratories to preserve tissue samples, preventing decay and maintaining cellular structure.
- Disinfection and Sterilization: Formaldehyde has strong disinfectant properties, making it very effective against bacteria, viruses, fungi, and spores. This makes it commonly used on laboratory equipment and surfaces.
- Vaccine Production: In vaccine research and production facilities, formaldehyde is used to inactivate viruses or bacterial toxins for medical purposes, rendering them harmless while maintaining their antigenic properties.
- Molecular Biology: Formaldehyde is utilized in molecular biology techniques to study protein-DNA interactions, chromatin structure, and gene expression. It helps stabilize nucleic acids for analysis, helping doctors and scientists do their jobs more efficiently.
- Biochemistry: In biochemistry labs, formaldehyde is used in various protein analysis techniques. It can be employed to cross-link proteins, helping to study protein-protein interactions, or to fix protein samples for electrophoresis.
- Environmental Testing and Management: Environmental science laboratories use formaldehyde in the analysis of air and water samples, as it is a common indoor and outdoor pollutant.
- Taxidermy: In laboratories involved in taxidermy and museum collections, formaldehyde is used as formalin to preserve animal specimens, ensuring their long-term stability and lifelike appearance.
- Anatomical Studies: In anatomical research and forensic studies, formaldehyde is employed to embalm cadavers. It helps preserve tissues for extended periods, allowing detailed study of human anatomy.
- Botanical Research: Formaldehyde solutions are used to preserve plant specimens before drying. They can also be used to create fertilizers and pesticides.
- Chemical Synthesis: Formaldehyde serves as a precursor in the synthesis of many other chemicals. It can be used to create various reactions among other chemicals, leading to the production of plastics, resins, and other complex organic compounds.
Safety Risks and How to Address Them
While formaldehyde is proven to be incredibly useful in laboratory settings, it is important to note its potential health hazards. It is classified as a carcinogen and can cause respiratory irritation and allergic reactions. Therefore, proper safety measures, including adequate ventilation, personal protective equipment, and careful handling procedures, are essential when working with this chemical.
Here are some of the most common safety risks associated with formaldehyde uses in laboratories and how they are best addressed:
- Inhalation Exposure: Formaldehyde vapors can cause respiratory irritation, coughing, wheezing, and shortness of breath. Laboratory workers should wear the proper respiratory protection and only work with formaldehyde in well-ventilated areas or in fume hoods.
- Skin and Eye Contact: Direct contact can cause skin irritation, allergic reactions, and eye damage. This can be avoided by wearing the appropriate Personal Protective Equipment (PPE) such as gloves, lab coats, and safety goggles.
- Flammability: Formaldehyde solutions can be flammable, making it a potential fire hazard. To ensure laboratory and fire safety, make sure to store formaldehyde in appropriate fire-resistant cabinets with the right safety procedures only, and keep them away from heat sources and oxidizing agents.
- Slips, Trips, and Falls: Improper handling of formaldehyde can lead to spills that can be a cause of workplace injury. For this reason, laboratory personnel should know how to handle formaldehyde safely with the right training, and have spill kits readily available.
- Environmental Contamination: When disposed of improperly, formaldehyde can leak into the environment, contaminating other living organisms and habitats, which can also lead to serious harm to humans through the food chain. Formaldehyde waste should be classified and handled as hazardous chemical waste, not disposed of in regular trash or down drains.
How Digital Tools Can Ensure Safe Formaldehyde Use in Laboratories
Digital tools can play a critical role in promoting the safe use of formaldehyde in laboratories by reducing the need for repetitive manual tasks, paperwork, and multiple back-and-forths. With platforms such as SafetyCulture, doctors, researchers, and other types of laboratory personnel can better improve safety in laboratories through by providing a centralized space to streamline safety protocols, enhance monitoring, and ensure compliance with different safety standards.
Some capabilities of digital tools that can help with enhancing the safety of laboratory procedures include the following:
Digital Checklists
Using modern digital tools allows for the creation of smart checklists for ensuring laboratory safety procedures are followed. These can include specific protocols for handling formaldehyde, making sure all personnel are aware of the right safety measures are followed consistently. Digital checklists also help streamline workflows, as they can be accessed on any device, anytime and anywhere.
Air Quality Monitoring
Some of the best digital tools for laboratory safety also offers air quality monitoring sensors that can detect formaldehyde. These sensors come with alerts that are triggered when concentrations exceed safe limits, allowing for immediate corrective actions to be implemented. This is crucial for maintaining safe levels of formaldehyde in laboratory environments and preventing overexposure.

Asset Management
Having asset management capabilities in a daily driver tool allows laboratories to maintain a detailed digital register of all assets, including those related to formaldehyde handling and storage. This comprehensive overview helps ensure proper tracking and management of formaldehyde-related equipment. It also helps with keeping inventory of safety equipment, laboratory glassware, rooms, and workstations, giving users insight into how these are utilized and when they might need replacements, maintenance, and inspections.
Incident and Issue Reporting
The most versatile and reputable laboratory management software today also allow workers to report incidents or unsafe conditions involving formaldehyde directly through mobile apps. With easily accessible and customizable report forms, users can raise any concerns they might have wherever they might be with ease. Real-time notifications can then help them be assured of an immediate resolution.
Training Modules
Certain digital tools also offer training modules to help guide workers on proper formaldehyde use in laboratory settings. Not only do these help with ensuring workplace safety, but these can also help ensure all laboratory operations and practices remain compliant with safety regulations. Some software can also track and verify that all required formaldehyde safety training has been completed by lab personnel, helping to ensure a comprehensive culture of safety.
