The device is a steam sterilizer intended to sterilize medical products, not to provide therapy directly to a patient.
No
The device is a steam sterilizer (autoclave) used to sterilize medical products by means of pressurized steam, not to diagnose a disease, condition, or state of health.
No
The device is a steam sterilizer (Autoclave), which is a physical piece of equipment with hardware components like a chamber, heaters, and safety features, in addition to electronic controls.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to sterilize medical products by means of pressurized steam. This is a process applied to medical devices before they are used on or with a patient.
- Device Description: The description details a steam sterilizer (autoclave) used for sterilizing instruments and glassware. It focuses on the physical process of sterilization.
- Lack of IVD Characteristics: An IVD device is intended for use in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform any such examination or analysis of biological specimens.
The device is a medical device used in a healthcare setting, but its function is sterilization, not in vitro diagnosis.

Device Description
The Astell Scientific range of UMB benchtop steam sterilizers are designed to offer convenience and flexibility in the sterilization of medical and surgical instruments. Instruments for sterilization include wrapped and unwrapped Metal Medical instruments, unwrapped Glassware and pouched dental hand pieces. A steam sterilizer (Autoclave) is a device that is intended for use by a health care provider to sterilize medical products by means of pressurized steam. Autoclaves/sterilizers heat water to generate steam as the sterilization agent, producing steam in the chamber to create a gravity displacement, pulsed dynamic air removal sterilization environment. Steam sterilization is a widely used sterilization process due to its versatility and speed. The sterilizers include as its main components a pre-programmed electronic control module, autofill water reserve, electronic heaters and an auto-drain sterilization chamber. The free-steaming phase of the sterilization process incorporates a 20-minute dynamic air removal program pulsing at low; 1200 mbar/ high;1600 mbar. The autoclaves are equipped with multiple safety features. The door contains a safety locking mechanism that does not permit operation unless the door is closed and locked, and does not permit the door to be opened until the internal chamber pressure is no greater than 100mbar above atmospheric pressure. Additional safety features include an automatic safety shutoff to prevent the chamber overheating; two (2) thermostats; one to detect overheating of the heaters and one to prevent opening of the door if the chamber temperature is unsafe to do so (80 °C). There is also a safety valve for the pressure vessel. A touch screen digital display with a user log, data archiving for up to 5000 cycles and multiple user access levels and multi-level password protection is used for precision control and monitoring purposes. The differences between the UMB Autoclaves/Sterilizers in this submission is the chamber volumes: UMB 220 (Total volume 33 Litres) UMB 230 (Total volume 43 Litres) UMB 240 (Total volume 63 Litres). There is an optional printer available to record cycle parameters. The UMB range of Autoclaves sterilization chamber is manufactured from Stainless Steel Grade 316 with the internal bore electro polished. The range are fitted with electronic heating elements, an autofill water reservoir and an electronic control system. The control system is pre-programmed with four sterilization cycles and up to a further 50 cycles available. There is also a safety valve test cycle.
