The quality of sample drying directly affects the accuracy and subsequent application value of experimental results in fields such as biopharmaceuticals, food testing, and material research and development. Shanghai Yetuo's new desktop freeze dryer, with innovative technology and user-friendly design, has become a "capable assistant" for laboratory sample processing, changing the pain points of low efficiency and complex operation of traditional drying equipment. From the perspective of core functions, the cooling and water capture capabilities of this device are particularly outstanding. Adopting a two-stage compression refrigeration system, the cold trap can quickly freeze the moisture in the sample to a solid state at a low temperature of -55 ℃, avoiding the loss of active ingredients caused by high-temperature drying. Whether it is enzyme preparations, probiotics and other biological samples, or volatile chemical reagents, they can be dried in a low-temperature environment. After drying, the moisture content of the sample can be reduced to less than 1% while maintaining its original form and activity. At the same time, the equipment is equipped with a 12L large capacity cold trap, with a water capture rate of 1.2kg/24h, which meets the simultaneous processing needs of multiple batches of samples without frequent shutdowns to clean frost, greatly improving experimental efficiency. In terms of intelligent functional design, Yetuo's new desktop freeze dryer also has highlights. Built in high-precision vacuum sensor and temperature sensor, can monitor the vacuum degree (range 1-60Pa) and sample temperature in the drying chamber in real time, and dynamically display them through a 7-inch touch screen. The device supports three-stage program settings of "pre freezing sublimation parsing". Users can customize the temperature and time parameters of each stage according to the characteristics of the sample. For example, for thermosensitive samples, the pre freezing time can be extended and the sublimation temperature can be reduced to ensure controllable drying process. In addition, the equipment also has an automatic fault alarm function. When the vacuum degree is abnormal or the refrigeration system fails, it will immediately sound and light an alarm and record the fault information, reducing experimental risks. The convenience of the operation process is another major advantage of this device. Di one-step, users only need to place the preprocessed samples into the drying chamber tray, close the door and tightly seal it, without the need for complex sealing debugging; Step 2: Select the preset program or custom parameters on the touch screen, click the "Start" button, and the device will automatically complete the pre freezing process - the cold trap will first drop to the target temperature, and after the sample freezes, the vacuum system will automatically start and enter the sublimation drying stage; Step three, during the drying process, users can view the vacuum degree and sample temperature curves in real-time through the screen, or remotely monitor them through a mobile app (supporting WiFi connection) without the need for on duty monitoring; Step four, after the drying is completed, the equipment automatically releases pressure and prompts to open the door to take out the dried sample. At the same time, press the "defrost" button, and the frost in the cold trap will quickly melt and be discharged through the drain. The cleaning process only takes 5 minutes. Whether it is small batch sample processing in scientific research laboratories or pilot testing needs in enterprise production lines, Yetuo's new desktop freeze dryer can provide users with stable and reliable drying solutions with convenient performance, helping to improve both experimental and production efficiency.
