Product Uses

钟罩规格图-Product Uses

A. (Standard Type): Comes with 4-6 layers of stainless steel trays. Suitable for the freeze-drying of bulk (liquid, paste, solid) conventional materials.

B. (Top-press Type): Equipped with 3 layers of stainless steel trays with adjustable spacing. It is suitable not only for the freeze-drying of bulk (liquid, paste, solid) conventional materials but also for the drying of materials in vials. During freeze-drying preparation, materials can be divided into vials as needed, sealed with caps, and then subjected to freeze-drying. After drying, the pressure cover device can be used to move and seal the vials in a vacuum state, making them suitable for long-term storage.

C. (Standard with Multiple Manifolds): Features 4-6 layers of stainless steel trays and an external hanging bottle attachment. Suitable for the freeze-drying of bulk (liquid, paste, solid) conventional materials and can also accommodate vials or wide-mouth bottles for drying. The external attachment is independent of the drying process and can be disassembled at any time. It can be used in conjunction with a concentrator to achieve both freeze-drying and concentration.

D. (Top-press with Multiple Manifolds): Combines the features of the pressure cover type and the regular type with multiple manifolds.

E. Type (Ampoule Tube): Equipped with 24 ampoule tube interfaces. Suitable for freeze-drying ampoule tubes containing microorganisms such as bacteria and fungi for preservation.

T. Type (External Hanging Bottle): Offers 8 external hanging bottle interfaces. External attachment allows for the drying of vials or wide-mouth bottles. The external attachment is independent of the drying process and can be disassembled at any time. The stainless steel T-shaped rack is corrosion-resistant and has a long service life. It can be used in conjunction with a concentrator to achieve both freeze-drying and concentration.

These configurations cater to various freeze-drying needs, from conventional materials to specialized applications like vial drying and ampoule tube preservation.

Product Operate Guide

Equipment Start-Up and Operation:

1. Navigate to the "System Menu" → "Operation Screen" and switch the 'Compressor' to "On."

2. After pre-freezing, place the material inside the drying chamber. Then, in the "Operation Screen," switch 'Vacuum Pump' and 'Vacuum Gauge' to "On."

3. Fully open the inlet/exhaust valve and wait for the chamber and cold trap to return to atmospheric pressure before removing and sealing the material. During shutdown, first re-inflate, then turn off the vacuum pump to prevent oil backflow, which could contaminate the samples.

4. Click the "Defrost" button; the defrosting process takes 30 minutes. Allow all ice in the cold trap to melt. Keep the drain valve open during this process, and it's recommended to place a container below the drain valve to collect the defrost water.

These operational steps facilitate a smooth start-up and operation of the equipment, ensuring a seamless freeze-drying process.

Vacuum degree does not reach below 15Pa

(1) Check the connection between the vacuum pump and the main unit to ensure it's properly secured.

(2) Check if the flat surface at the lower end of the organic glass cover is clean and undamaged.

(3) Check if the "O"-ring gasket is clean and properly placed.

(4) Check if the vacuum pump is operating correctly and observe if the pump oil is clean.

(5) Check if the vacuum valve is tightened.

Vacuum pump oil leakage

(1) Inspect the machine body and replace the required parts.

Cold trap temperature is too high

(1) The ambient temperature is too high, and there is poor heat dissipation. Place the machine in an appropriate temperature environment with good ventilation.

(2) Check for dust on the cooling fins in the machine case and on the condenser, and ensure that the fan is operating normally.

(3) If the refrigeration system is faulty, contact the company's technical engineer.
