Freeze drying is an important process in sample preparation and for the preservation and storage of biologicals, pharmaceuticals and foods. Of the various methods of dehydration, freeze drying (lyophilization) is especially suitable for substances that are heat sensitive. Other than food processing (e.g., coffee, whole dinners), freeze drying has been extensively used in the development of pharmaceuticals (e.g., antibiotics) and preservation of biologicals (e.g., proteins, plasma, viruses and microorganisms). The nondestructive nature of this process has been demonstrated by the retention of viability in freeze dried viruses and microorganisms.
Freeze drying is a process whereby water or other solvent is removed from frozen materials by converting the frozen water directly into its vapor without the intermediate formation of liquid water. The basis for this sublimation process involves the absorption of heat by the frozen sample in order to vaporize the ice; the use of a vacuum pump to enhance the removal of water vapor from the surface of the sample; the transfer of water vapor to a collector; and the removal of heat by the collector in order to condense the water vapor. In essence, the freeze dry process is a balance between the heat absorbed by the sample to vaporize the ice and the heat removed from the collector to convert the water vapor into ice.
This manual is designed to help you learn how to install, use, and maintain your Freeze Dryer. Instructions for performing routine maintenance and making minor modifications to your Freeze Dryer are also included.
Note:As a company with technology as its core driving force, we have been always committed to technological innovation and optimization, ensuring that our software can be updated iteratively.

In view of the continuous upgrading of products and the ongoing updates of software, the actual product software information may change at any time. If there are slight differences between the instruction manual you received and the actual device at hand, but these differences generally won’t hinder your normal use, please rest assured that we will provide you with the updated instruction manual in a timely manner.
Before you install your Freeze Dryer, you need to prepare your site for installation. Carefully examine the location where you intend to install your Freeze Dryer. You must be certain that the area is level and of solid construction. An electrical source must be located near the installation site.
The Freeze Dryer requires a dedicated electrical outlet. This outlet requires a (SJ-05H: 220v 10A,or 110V 20A;SJ-08H:220v 15A,or 110V 20A ) circuit breaker or fuse is required for models rated at 220V-240V (50 Hz). The power cord on 220-230V models are equipped with a plug on the power cord. It will be necessary to change a plug to match the available receptacle.
Carefully unpack your Freeze Dryer and inspect it for damage that may have occurred in transit. If your Freeze Dryer is damaged, notify the delivery carrier immediately and retain the entire shipment intact for inspection by the carrier.
