In the summer laboratory, the air conditioning is running at full power, but it can't stop the heat wave from running around in the small space. The freshly cut fruits and vegetables wilt and droop after half an hour, and the bacterial liquid samples become inactive and spoiled without even noticing. Even those who want to make some summer limited freeze-dried snacks during the holiday are hindered by this high temperature and high humidity weather. It wasn't until my "summer savior" - Shanghai Yetuo's new desktop freeze dryer - officially started working that I finally solved all kinds of preservation and experimental problems in high temperatures, and became my favorite that I couldn't do without throughout the summer. The more I used it, the more I loved it.
To call it a summer helper, first praise its unique 'anti season superpower'. On a scorching day of thirty-seven or eight degrees outside, the sun was scorching the ground, and the thermometer in the laboratory was always hovering high. However, with the help of a cascade compressor, it was able to directly dry the temperature of the cold trap to -60 ℃. The inside and outside of the machine were like two worlds of ice and fire. In summer, I crave various seasonal fresh fruits such as bayberries, lychees, peaches, and loquats, all of which are fresh, tender, and juicy. However, their shelf life is short. If I buy too few, I won't be able to eat them. If I buy too many, they will rot in the refrigerator within two days, and I feel heartbroken if I throw them away. Since the advent of freeze-drying machines, this problem has been easily solved. Wash and cut fresh fruits, perform simple preprocessing, and place them on a tray. Once placed in the freeze dryer, it begins to perform low-temperature magic: first, quickly freeze the fruits to turn water into solid ice crystals, and then in a high vacuum environment, let the ice crystals directly sublime into water vapor and be captured by the cold trap. The entire process does not require high temperature heating, and the sweet juice and fruity aroma of summer fruits are firmly locked in the flesh. The freeze-dried waxberries come out crispy, with a sweet and sour taste that is not greasy or sticky. The freeze-dried lychee retains its original sweetness, while the freeze-dried peach slices have a faint fruity aroma, much more fragrant than the industrial freeze-dried dried fruits bought in supermarkets. Take a few fish during the experiment break. The cold and crispy taste instantly soothes the restlessness caused by high temperatures, even more satisfying than ice cola or ice milk tea. It's a perfect summer exclusive snack for the laboratory.
Not only can it help me achieve 'summer dried fruit freedom', but in serious scientific research, it is also the 'stabilizing sea needle' in high temperatures, specializing in treating various difficult and complicated problems in sample preservation. Those who conduct biological experiments know that summer is the "transitional period" for samples. Proteins, strains, serum, cells, and other "delicate goods" on the scientific research path are particularly sensitive to temperature and easily lose their activity when exposed to a little heat. When there was no lyophilizer before, the processed samples had to be carefully placed in the refrigerator and moved with care. If they needed to be transported, they had to be wrapped in three layers of ice packs inside and outside, and stored in an insulated box. They were worried all the way, afraid that the ice packs would melt and cause the samples to be scrapped. They had suffered from this kind of loss several times before, and had to work hard for most of the experiment. Don't hesitate too much. Now with this new desktop freeze dryer from Shanghai Yetuo, everything has become simpler. The pre processed samples are placed in penicillin bottles or trays, and the preset freeze-drying program is activated with one click. The entire process of pre freezing, sublimation, and analytical drying is automated, and the 7-inch color LCD touch screen displays temperature, vacuum degree, and drying progress in real time. All data is clear at a glance, and I don't have to stand by and watch. I should do other experiments, fish and fish, which is both worry free and effortless. After freeze-drying, the moisture content of the samples is so low that they can be stored for a long time at room temperature and sealed. There is no need to compete with laboratory refrigerators and freezers for space, and those precious samples finally have their own "protective house". Even if it needs to be sent to other laboratories for collaborative research, there is no need to tinker with ice packs and insulated boxes. Simply seal and pack the boxes, and you no longer have to worry about temperature issues during transportation. Say goodbye to the anxiety of sample transportation.
Its thoughtfulness is also hidden in various small details used in summer, understanding the "lazy needs" of workers and researchers. As a desktop model, it is small and compact in size, unlike large freeze-drying machines that take up space. The laboratory is already filled with various instruments and reagent bottles, and the space is narrow. When it is placed in a corner, it is just right and not a problem at all. And the noise during operation is particularly low, with only a slight buzzing sound, which will not add to the annoyance in the stuffy laboratory. Even if it is turned on for a long time, it will not affect our experiments and discussions, and we can do the work quietly. Cleaning is also particularly convenient. The 304 stainless steel cold trap and tray, whether it is residue left by freeze-dried fruits or slight residue of biological samples, can be simply wiped, rinsed with clean water, and then dried after the experiment, without the need to disassemble and clean. I am already lazy to do big cleaning in the summer, which really hits me. More importantly, it can also be used in multiple ways, unlocking various summer scenarios. In addition to freezing fruits and processing biological samples, if you occasionally want to change your taste, try freeze-dried yogurt cubes, freeze-dried banana slices, freeze-dried flower tea, and even small batches of pharmaceutical and cosmetic ingredients in the laboratory that can be easily dried. There are more than ten pre installed freeze-drying programs in the body, which are tailored to different materials such as fruits, vegetables, biological samples, dairy products, etc. Without me repeatedly pondering parameters and debugging equipment, even beginners who have just started working with freeze-drying machines can get started with just one click of the program, truly achieving a foolproof operation.
In summer, the laboratory was originally a battlefield swept by high temperatures, but with this freeze-drying machine, there is a lot of relaxation and happiness. It can lock the limited freshness of summer into eternity, turning perishable seasonal fresh fruits into delicious ones that can be stored for a long time; Can prevent scientific research experiments from collapsing in high temperatures, safeguard the activity of every precious sample, and prevent our experimental progress from being hindered by weather; We can also easily make various freeze-dried snacks without any additives, bringing us a hint of sweetness and coolness during busy experimental breaks. It doesn't need a fancy appearance, but relies on stable performance and thoughtful design. In the scorching sun, it uses low-temperature magic to keep freshness, scientific rigor, and the calmness in the laboratory.
Who can refuse a freeze-drying machine that can not only conduct scientific research, facilitate the smooth progress of experiments, but also make snacks, achieve freedom in summer fruit drying, and specialize in various preservation and storage problems in summer? Anyway, this desktop freeze dryer is undoubtedly my 'life's helper' this summer. From early summer to midsummer, the more I use it, the more I feel indispensable. It's a perfect summer laboratory product!
