Due to COVID-19, some materials included in your lab kit may differ slightly from what is described in your lesson. All substitutions are evaluated by our team of experts for safety and usability. Please reference the notes and instructions below when using any substituted material.
What has changed.
We are currently experiencing a shortage of sterile swabs due to COVID-19.
What you should do.
In place of the sterile swabs, please purchase cotton swabs, such as Q-tips. Cotton swabs can be purchased at your local drug store in the make-up section. You can use either single ended or double ended cotton swabs for these experiments. Once opened, store your cotton swabs in a resealable container in a dry, clean location.
To use your cotton swabs in your experiments, follow the protocol directions as written.
