Features
The temperature of the inner wall of the cold trap is uniform, and the professional gas diversion technology has a good water replenishment effect.
Adopt brand compressor, single-machine mixed environmental protection refrigeration technology.
Configure the cold trap sample pre-freezing function, no need for ultra-low temperature refrigerator or liquid nitrogen treatment.
7-inch color LCD touch screen, friendly human-computer interaction interface, equipped with lock screen function, optional mobile phone, computer remote control.
The main interface of the display screen is simple and clear, showing parameters such as cold trap temperature, vacuum degree, sample temperature, running time, etc. The operation is simple and direct, and misoperation authority management is set.
It has the functions of viewing, exporting and deleting. Freeze -dried data is automatically saved to prevent data loss. It supports USB data export.
Supports lyophilization of ampoules, vials, glass flasks, plasma vials or trays.
The cold trap has the independent pre-freezing function of the sample in the early stage, and is equipped with a one-key defrosting function.
Built-in maintenance reminder function to remind users of instrument maintenance.
With vacuum alarm function, it can timely remind users whether the vacuum degree is normal.
High-precision micro-adjustment vacuum valve, which can realize micro-adjustment of vacuum degree.
Equipped with stainless steel anti-corrosion vacuum connection tube, with standard KF25 vacuum quick-connect clamp.
