The HIP chemical (HYDRIM Cleaning Solution with Instrument Protection) has been carefully formulated to provide outstanding compatibility with a wide range of materials and coatings. HIP is automatically added at various stages in the cycle to optimize the cleaning and protection of instruments. Independent testing of the HIP cleaning solution in the HYDRIM Instrument Washers and Washer-Disinfectors indicates 99.9% protein removal — far beyond the level detectable with the naked eye!
