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.

Product Video


SY-18 and SY-12 have both similarities and differences:


1. Both SY-12 and SY-18 are floor-standing freeze dryers with caster wheels for easy mobility.

2. They operate using the same principles and have similar usage methods.


1. SY-18 has a larger freeze-drying area. The standard freeze-drying area for SY-18 is 0.18 square meters, expandable to 0.27 square meters, while SY-12 has a freeze-drying area of 0.12 square meters.

2. SY-18 has a larger cold trap compared to SY-12. This means that SY-18 has a higher capacity and can accommodate more samples.
