Swabs, alcohol prep pads and other supplies related to skin preparation for biopotential measurement are located here.  Let us know if you use a product to prepare the skin that you would like us to carry.  As a general rule, we recommend that you use only sterile products to prepare the skin, since there is a possibility of breaking the skin and drawing blood if you are too vigorous in your efforts to reduce skin impedance.  By the same token, we recommend that you consider all sterile skin preparation implements as single-use products to minimize the risk of cross infection.  Re-user of some sterile products is not only frowned upon, but may be prohibited in some regions.
