Description
Technical Parameters
A Laboratory Lyophilizer,also known as a lyophilizer,is a specialized equipment used in scientific research and industrial applications to remove water or other solvents from samples through a process called freeze-drying or lyophilization.This process involves three main steps:freezing,primary drying,and secondary drying.
During the freezing step,the sample is cooled to a temperature below its eutectic point,ensuring that the solvent forms ice crystals within the material.In the primary drying phase,the ice crystals are sublimated directly from solid to vapor under vacuum conditions,removing most of the water or solvent.Finally,in the secondary drying step,residual unbound water or solvent is removed by desorption,further reducing the sample's moisture content.
Laboratory Lyophilizers are designed with precise temperature and vacuum control systems to ensure efficient and uniform drying of samples.They are widely used in various fields,including biotechnology,pharmaceuticals,food processing,and materials science,for preserving delicate biological samples,stabilizing drugs,and creating porous materials with unique properties.

Types for Various Use
Freeze dryer machine for laboratory, are essential equipment for preserving and stabilizing samples,particularly biological specimens and pharmaceuticals,through a process called freeze-drying or lyophilization.There are several types of them available,each designed to meet specific research and industrial needs.Here are some of the common types:
Benchtop Freeze Dryers:These are compact,standalone units designed for use on a laboratory bench.They are typically smaller in capacity but offer ease of use and portability,making them suitable for small-scale experiments and research projects.
Floor-Mounted Freeze Dryers:These are larger units that require floor space.They have higher capacities and are designed for larger-scale freeze-drying applications,such as in pharmaceutical research or industrial production.
Manifold Freeze Dryers:These feature a manifold system that allows for multiple samples to be processed simultaneously.They are ideal for high-throughput laboratories or when multiple samples need to be freeze-dried simultaneously.
Touchscreen-Controlled Freeze Dryers:These units incorporate advanced touchscreen technology for intuitive and user-friendly operation.They often have programmable settings and automated features that simplify the freeze-drying process.
Cryogenic Freeze Dryers:These use extremely low temperatures,often achieved through liquid nitrogen or other cryogenic agents,to achieve faster and more efficient freeze-drying.They are commonly used for samples that are sensitive to higher temperatures.
Modular Freeze Dryers:Modular designs allow for customization and scalability.These can be configured to meet specific research or production needs,and their modular nature makes them easier to upgrade or expand in the future.
When selecting a Laboratory Lyophilizer,it is important to consider factors such as sample size and type,throughput requirements,budget,and available space.The choice should also take into account the specific freeze-drying protocols and conditions required for the intended application.
Sample prefreezing
The main purpose of sample pre-freezing is to freeze all the liquid water in the sample into ice crystals,so that in the subsequent vacuum drying stage, the ice crystals are directly converted into water vapor by sublimation,thus removing the water in the sample.
Prefreezing method
Slow freezing
Put the pre-treated sample into the cold trap,cover the insulation cover,and then open the refrigerator(compressor)for pre-freezing.This method is suitable for most samples,and the pre-freezing time depends on the characteristics of the sample and the degree of freezing required.
Rapid freezing
First turn on the refrigerator,wait for the temperature of the cold trap chamber to drop to a certain degree,and then quickly put the sample into the cold trap for pre-freezing.This method is suitable for samples that require rapid freezing in order to reduce the chemical or physical changes that may occur to the sample during freezing.
Prefreezing condition
Temperature
It is usually necessary to lower the cold trap temperature below -40 ° C to ensure that the water in the sample can completely freeze into ice crystals.The temperature depends on the characteristics of the sample and the degree of freezing required.
Time
The pre-freezing time depends on the characteristics of the sample and the degree of freezing required,and generally takes 2 to 4 hours or more. During the pre-freezing process,the sample temperature should be checked periodically to ensure that the sample has been completely frozen.
Sample thickness
In order to ensure the freezing effect,the thickness of the liquid sample should be less than 1cm.If the sample is thick,it may be necessary to extend the pre-freezing time or use other freezing methods.
