HiYi Lyo-cube Small Vacuum Freeze Dryer Pre-freezing Lyophilisers

In-situ freeze dryer is a device used to prepare powdered or flaky samples. It can evaporate water from the material and turn it into a dry state. It adopts advanced refrigeration structure and technology, through automated process procedures, convenient operation design, and precise control system, it ensures reliable data and highly repeatable experimental results for users.

1. in-situ pre-freezing: samples are pre-frozen and dried in the cold trap without moving, and the whole process is completed by automatic control, which is convenient for operation and reduces intermediate links;
2. adopts double compressor compound stack refrigeration unit, low noise, stable and reliable performance;
3. ultra-low temperature condensation coil, greatly improving its water trapping capacity, preventing water from escaping into the vacuum pump;
4. low pre-freezing temperature, which is conducive to the shaping of sample preparation;
5. the use of environmentally friendly non-fluorine refrigerant, in line with environmental requirements;
6. shelves with heating system, large screen LCD touch screen can be preset heating procedures, by the PID intelligent regulation, multi-segment programme temperature control, improve the speed of freeze-drying.

In-situ pre-freezing lyophilisers have a wide range of applications. For example, in the pharmaceutical industry, it is commonly used to prepare preparations such as oral solids, injections and nasal sprays. It is also widely used in biotechnology, the food industry and the chemical industry. In these areas, it can help to prepare high-quality samples and enables a highly controlled drying process, which ensures the stability and consistency of the samples.​
