- Small medium-sized freeze-drying machine
- Working conditions
1.1 Working temperature: 5-30 ℃
1.2 Working humidity: ≤ 80%
1.3 Power supply: 220V 50HZ 2000W
2. Technical Requirements and Configuration
2.1 Main functions:
2.1.1. * The small and medium-sized test box type freeze-drying machine is designed with a single double chamber structure, and the cold trap and freeze-drying chamber are relatively independent. The pressure difference and temperature difference between the cold trap and freeze-drying chamber are easier to form, improving the freeze-drying efficiency and enhancing the freeze-drying effect.
2.1.2. Advanced system refrigeration technology, stable refrigeration, high efficiency, cold trap temperature -50 ℃
2.1.3. Box type stainless steel condensing coil design, strong water capture ability, corrosion resistance, ZUIDA protection vacuum pump, water capture capacity of 6kg
2.1.4. Vacuum pumping rate and ultimate vacuum: 4L/S; Extreme vacuum: 5pa;
2.1.5. The vacuum size can be adjusted and controlled.
2.1.6. Inert gas backfilling function, one click defrosting, reduces sample secondary pollution, and can be backfilled with nitrogen or inert gas. Equipped with a 0.2um ultrafiltration gas device, effectively protecting the material from contamination.
2.1.7. Description of freeze-drying capacity: Two layer partition size: 280mm x 360mm x 15mm, ≤ 380 22mm penicillin bottles or ≤ 600 16mm penicillin bottles; 250ml 500ml standard configuration is 250ml; ZUIDA freeze-drying area 0.2 ㎡
2.1.8. After freeze-drying, one click vacuum release function.
2.1.9 * Permission protection three-level permission password, factory password, engineer password, and operator freeze-drying process password. Convenient for system setup, sensor calibration, freeze-drying process management, etc
2.1.10. The control system is designed for a 7-inch LCD touch screen control, and users can calibrate the touch screen themselves. Transparent observation window for easy observation of material freeze-drying status
2.1.11. In situ freeze-drying: The pre freezing of the sample is carried out in a partition inside the freeze-drying chamber, not outside the instrument using a refrigerator or other refrigeration equipment, nor in a cold trap.
2.1.12. The operating system has two modes: manual freeze-drying and automatic freeze-drying, and the system can upgrade the common melting point testing function
2.1.13. Freeze drying process management function: segment jump can be achieved based on the freeze-drying situation. It is possible to modify the freeze-drying scheme and enter a password to modify the running freeze-drying scheme. Monitoring of cold well temperature, separator temperature, sample temperature, and vacuum degree process parameters.
2.1.14 * Freeze drying process editing: Each segment can edit temperature and running time. You can edit the vacuum section and end section functions. You can enter your own freeze-drying process password to enter the program for editing and modification.
2.1.15 *. It has 35 freeze-drying and freeze-drying process plans that can be set with passwords, 1 initial freeze-drying plan, and a maximum of 40 segments can be edited for partition heating control. Partition temperature control range: ambient temperature range to 60 ℃
2.1.16. Freeze drying curve and freeze-drying data: Continuously record real-time data, draw freeze-drying curve, record data once per minute, and have a backup USB data storage port. Real time freeze-dried koji
