Experimental animal specific pulsating vacuum sterilizer

The STM-EA series pulse vacuum sterilizer for experimental animals is one of the high-end sterilization equipment series developed and produced by our company according to the latest national requirements for sterilization equipment. It is a high-end disinfection and sterilization device that fully complies with GMP specifications and is also an ideal replacement product for the experimental animal industry, hospitals, pharmaceuticals, biotechnology and other industries. This sterilizer is specifically designed for the sterilization of animal feed, drinking water, cages, clothing, and other feeding supplies in the experimental animal industry. Multiple sterilization procedures are available to meet all daily sterilization needs of the experimental animal center.  

1. Material of the cavity: The annular reinforcing rib structure and the unique combination of the inner shell and annular jacket enhance the strength and stiffness of the main body. The inner shell and annular reinforcing ribs are made of stainless steel material specifically designed for 316L pressure vessels; The main design lifespan is 15 years. Multi point steam inlet, multi-stage heating, temperature gradient facilitates internal steam convection, temperature distribution is more uniform, and steam consumption is saved.  

2. Control system: Using Siemens PLC from Germany, data during operation is printed through a printer, with a reserved computer remote monitoring interface. It supports industrial Ethernet, can be remotely maintained through the Internet, and supports numerous network protocols such as TCP/IP. Printing data allows for selection between Chinese and English.  

3. The front panel touch screen of the device adopts a stable performance German Siemens 7-inch color touch screen with a resolution of ≥ 800 × 480, IP≥65， Supports RS-22, RS-485, TCP/IP communication. The operation interface can switch between Chinese and English.  

4. Program selection: equipped with 121 ℃ feed sterilization, 121 ℃ plastic item sterilization, 134 ℃ metal item sterilization, 134 ℃ fabric sterilization, 121 ℃ open container liquid sterilization, 121 ℃ solid waste sterilization, 134 ℃ pad material sterilization, 134 ℃ plastic item sterilization, 121 ℃ rapid liquid program, BD testing, vacuum testing, printing testing or offline printing program, custom program. The entire process is automatically controlled, with low and high temperature alarms and misoperation protection prompts;  

5. Work permissions: three-level permission management for administrators, technicians, and operators to ensure the normal operation of equipment.  

6. Operation mode: It has automatic mode and manual mode. In manual mode, it can display the overall pipeline, valves, vacuum pumps, and the on/off status of various valve components of the equipment, making it easy to visually observe the status of the equipment and improve safety.  

7. Calibration function: The control system is equipped with a calibration program that can calibrate parameters such as pressure and temperature in different altitude areas.  

8. Recording method: The temperature, pressure, time, process stage, preset parameters, etc. of the sterilization process should be automatically displayed on the touch screen, with a USB interface reserved for exporting data to a USB drive for storage; Equipped with printer to print process parameters.  

9. The door sealing ring is made of high tear resistant silicone rubber material, with a surface treated with Parylene coating, which is wear-resistant and smooth. Compared with rectangular sealing rings, it has better sealing effect and longer service life, with a lifespan of up to 1500 cycles.  

10. The sealing gasket of the high-temperature pipeline clamp is made of polytetrafluoroethylene material instead of silicone rubber, which has a longer service life;

11. Vacuum pump: single-stage direct connected water ring vacuum pump, no belt transmission, protection level IP55, water inlet method is preset water tank self-priming vacuum pump, rejecting direct water supply vacuum pump causing water source waste.  

12. Pipeline requirements: Pipeline material: 304 stainless steel pipeline, pipeline design layout is reasonable, avoiding blind pipes and dead corners, using clamp connections, and polishing treatment inside and outside the pipeline.  

13. Pneumatic valve: A stable performance pneumatic valve with a typical fault free opening and closing frequency of ≥ 4 million times.  

14. Sealed door: The motor gear chain drives the door panel to move up and down, and the side opening cabinet door is opened. The number of teeth meshing with the main body is ≥ 13. Double door channel type, motorized door, equipped with safety interlock device, double door interlock to ensure effective isolation of the front and rear areas of the sterilizer;  

15. Equipped with an intelligent maintenance system: it automatically monitors the operating status of various components and prompts various maintenance information, such as door gasket replacement, air filter replacement, switch mechanism lubrication maintenance, filter cleaning, etc; Ensure that the equipment is always in normal working condition (to prevent potential faults in advance, such as avoiding damage to the door seal ring during operation and affecting the normal production of customers);  

16. Adopting plate heat exchangers with a heat transfer efficiency of ≥ 95% and a long service life.  

17. Equipped with water-saving and noise reduction devices, as well as condensate water recovery devices, it saves energy.  

18. The optional biosafety emission filtration system ensures the safe discharge of water vapor during the sterilization process and meets the requirements for the treatment of infectious waste in biosafety laboratories. The water vapor filtration system consists of a filter element with a pore size ≤ 0.2um filter membrane, which contains a temperature probe and is sterilized online during the sterilization process. It also has a reminder function for filter element replacement when it expires; During the heating and sterilization process, the condensate is retained inside the pressure vessel while undergoing sterilization.  

19. Equipped with flash evaporation vacuum drying technology, the drying degree of the equipment is less than 0.1%.
