Nanomaterials, and in particular carbon nanotubes, possess a high surface area coupled with low density. This combination of properties renders a challenge in handling them safely, as they are susceptible to static charges, and also tend to disperse rapidly into the environment during routine handling. Their relative lightness and ease of dispersion in air also means that they cannot be handled easily in a laboratory fume hood with active air flow. One option would be to use a glove bag, but this may not always be available. Herein, we outline a safe and simple method to handle bulk amounts of low-density nanomaterials using an improvised glove box. Given the rapid rise in the manufacturing of nanomaterials, our approach may be an easy, approachable way to achieve safer working conditions-especially in the case of laboratories with constrained budgets, or start-up companies.
