How do I choose the artificial perspiration that’s right for me?
Makers of smart watches, high performance textiles, biosensors, heads up displays, and fitness monitors all have one thing in common – the need to test their products for quality assurance. Personal electronics and wearable technology manufacturers perform sweat testing on materials including touch screens, watchbands, keyboards, eyeglasses, and any other product material or surface that would benefit from guaranteed reproducible results with artificial perspiration. By using Pickering Laboratories’ artificial eccrine perspiration, our customers are able to save time and ensure the same repeatable results anywhere, anytime.
Normally,a sweat mimic is prepared at the time of the test according to an industry specific formula. The American Society for Testing and Materials (ASTM) describes procedures to test many products in the presence of a sweat mimic. According to Michael Pickering, Founder/Owner of Pickering Laboratories, “we were guided by the multiplicity of such tests to develop an artificial perspiration that can yield reproducible results independent of the test.”
Pickering Artificial Eccrine Perspiration is the closest mimic available to actual eccrine perspiration, and we prepare two versions. The stabilized version has a preservative which prevents microbial growth and can then be stored at room temperature. The non stabilized version has no preservative and must be kept frozen until you intend to use it. You may need this version if you are testing a product that claims to prevent microbial growth or odor from perspiration. Our Artificial Eccrine Perspiration normally comes at pH 4.5, however, we can make it custom from pH 3.0 – 9.0.
1700-0020 – Sweat, Stabilized 1700-0022 – Sweat, Not Stabilized
1700-0021 – Sweat, custom pH, Stabilized 1700-0023 – Sweat custom pH, Not Stabilized
Are you required to follow a specific testing method? If so, we may already carry the exact artificial perspiration formula for that particular method. If you don’t see it on this list, please contact us with a copy of your method and we will investigate making it for you.
