It is used to monitor steam sterilization cycles in gravity and vacuum-assisted steam autoclaves. Upon exposure to steam at temperatures between 121-134°C, the ink undergoes a temperature-dependent chemical reaction, changing color from white to purple via a pink intermediate. This visual change confirms that the device has been exposed to the sterilization process. The device is intended for use by healthcare personnel in clinical settings to verify autoclave performance. ## Clinical Evidence Bench testing only. Performance evaluated in a BIER vessel/prototype conforming to ANSI/AAMI ST45-1992. Testing confirmed color change from white to purple (pink intermediate) in partial cycles at 121°C and 134°C. Development of end-point response required ≥7 minutes at 121°C and ≥3 minutes at 134°C. ## Technological Characteristics Paper strip with chemical indicator ink pads. Operates via temperature-dependent chemical reaction. Designed for gravity and vacuum-assisted steam autoclaves (121-134°C). Performance testing conducted per ANSI/AAMI ST45-1992. ## Regulatory Identification Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device. ## Predicate Devices - Strate-Line™ Sterilization Indicator Strip, Propper Manufacturing Co., Inc. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Chancery House 190 Waterside Road Hamilton Industrial Park Leicester LE5 1QZ ## CONTACT PERSON Alan Charlton Chancery House 190 Waterside Road Hamilton Industrial Park Leicester LE5 1QZ ### DATE PREPARED December 16, 1997 #### 2. DEVICE NAME Browne MVI Steam Indicator CLASSIFICATION NAME Physical/chemical sterilization process indicator CLASSIFICATION STATUS Physical/chemical process indicator is classified as Class II under Sterilization process indicator in 21 CFR 880.2800 by the General Hospital and Personal Use Devices Panel. {1}------------------------------------------------ #### 3. PREDICATE DEVICE Strate-Line™ Sterilization Indicator Strip, Propper Manufacturing Co., Inc. #### 4. INTENDED USE The Browne MVI Steam Indicator is a sterilization process indicator designed to indicate, through a visible color change, when the device has been exposed to a steam sterilization process. #### DEVICE DESCRIPTION 5. The Browne Steam Indicator is a paper strip with indicator ink pads on each end which is used to monitor steam sterilization cycles. The indicator ink changes color from white to purple through a pink intermediate in a steam autoclave working at 121-134°C. #### 6. TECHNOLOGICAL CHARACTERISTICS The Browne MVI Steam Indicator consists of a paper strip with chemical indicator ink pads located on each end. The device is designed to monitor steam sterilization processes in gravity and vacuum-assisted steam autoclaves with a working range of 121-134°C. The color change in both devices is produced by a temperaturedependent chemical reaction. #### 7. PERFORMANCE TESTING All performance testing was conducted in a BIER vessel/prototype which conforms to the performance requirements for BIER/Steam vessels described in ANSI/AAMI ST45-1992. Testing was conducted to evaluate the performance of the strips in partial cycles at 121°C and 134°C. The data showed that the strips changed color from white to purple with a pink intermediate. The time required for complete development of an end point response was ≥7 minutes at 121°C and ≥3 minutes at 134°C. The data demonstrates that the device can be used for the confirmation of exposure to a steam sterilization process in a steam autoclave with a working range of 121-134°C. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the seal of the U.S. Department of Health and Human Services.
