Lab Freeze Dryer with Cold Trap -60℃ to -102℃ | Compact Benchtop Lyophilizer with Multiple Models

1. The cooling system

·Equipped with:

1) A hermetic compressor;

2) A plate heat exchanger;

3) A high-power condenser;

·The refrigeration technology utilized in this system is eco-friendly, employing a blend of mixed refrigerants and a single compressor;

·Stable, low vibration, low noise;

·The cold trap’s temperature is low and the number is real.

2. The control system

·Equipped with:

1) A two-stage rotary vane vacuum pump to prevent oil return;

2) KF-25, the standard size for quick flange fittings;

3) A 5" color touch screen:

- Record and present real-time data. Get an at-a-glance view of live readings, including vacuum pressure, cold trap temperature, and material and shelf temperatures. These readings collectively construct the freeze-drying curve;

- Efficiently capture and continuously monitor comprehensive data on the material and the freeze dryer’soperational status;

- Off-linedata is available for analysis, printing, and storage;

4) USB ports.

·Automatically monitor the vacuum pressure. If the vacuum pressure fails to reach the designated setpoint within the stipulated timeframe, an automatic  shutdown of the vacuum pump is triggered;

·Access the cumulative operating hours of the vacuum pump, serving as a reliable indicator to determine the optimal timing for changing the vacuum pump oil;

·The compressor incorporates a restart delay mechanism, and an integrated thermal overload module is employed to safeguard the freeze-dryer from  overheating.

·A PID controller is utilized to precisely manage the temperature ramping program of the shelves, which are coated with a cutting-edge heating film commonly employed in aerospace. The inclusion of thermal overload protection helps make it safer and more reliable;

·The sublimation process can be controlled either automatically or manually.

3. Structural designs

·Casing: a curved integrated structure;

·Display: a circular round screen, positioned at a forty-five-degree angle to the freeze-dryer. This  design  conforms  to  ergonomics,  making  it  simple, elegant, and aesthetically pleasing;

·The top surface is constructed from 304 stainless steel, renowned for its exceptional corrosion resistance and resistance to acids and alkalis;

·The cold trap’s design features a generously sized opening and omits the need for  internal  condenser  coils  (which  9C  has),  helping  speed  up  the sublimation process and facilitating convenient CIP (clean-in-place) procedures. Without the condenser coils, the cold trap offersample room for accommodat- ing shelves and pre-freezing samples, saving you the trouble of purchasing a separate ULT freezer or utilizing liquid nitrogen to pre-freeze samples;

·A distinctive flange design is employed in the cold trap to prevent frost build-up;

·A distinctive corrugated seal is created through molding, resulting in multiple layers of sealing that provide enhanced protection.
