Laboratory scale vacuum freeze dryers are widely used in medicine, pharmaceutical, biological research, chemical and food fields.Freeze-dried items are easy to store for a long time, and can be restored to the state before freeze-dried and maintain the original biochemical properties after adding water. It is suitable for laboratory use and can meet the requirements of routine freeze-drying in most laboratories.
Freeze dryer, also called a lyophilizer, gently removes moisture through low-temperature freezing and vacuum sublimation. It preserves color, nutrients, aroma, and activity, making it ideal for food, pharmaceuticals, biotechnology, herbs, and pet food. We offer household to industrial models for both small-batch research and large-scale production.
①Integrated structure design, small size, easy to use, no leakage.
② All materials in contact with the product are made of inert materials to meet the requirements of GLP.
③ Large opening of cold trap, no inner coil, with sample pre-freezing function, no need for low temperature refrigerator.
④ Specialized gas diversion technology, cold trap ice evenly, ice capture ability.
⑤ Vacuum pump protection function, can set the vacuum pump start cold trap temperature, protect the service life of the vacuum pump.
⑥ 7-inch true color industrial embedded touch screen +SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.
⑦ Intelligent data recording system, real-time record and display cold trap temperature curve, sample temperature curve, vacuum degree curve, exported data can be viewed and printed through the computer and a variety of operations.
⑧The powerful sensor calibration function ensures the accuracy of the measured value in long-term use.
