Key Features
Low temperature rapid drying
Vacuum drying chambers can significantly speed up drying at lower temperatures by reducing the boiling point of water. This characteristic makes it particularly suitable for temperature-sensitive materials, such as biological products, pharmaceuticals, etc., which can achieve rapid drying while maintaining the activity of the material.
Uniform heating
The heating source is evenly distributed inside the box to ensure that the sample is heated evenly and avoid overheating or uneven local temperature, thereby improving the drying effect.
Intelligent temperature control system
The use of intelligent digital temperature regulator for temperature setting, display and control, with PID self-tuning function, can accurately control the temperature in the box to meet the drying needs of different samples.
Over-temperature protection
The equipment has over-temperature protection function. When the temperature in the working room exceeds the set temperature value, the over-temperature protection circuit will automatically cut off the heating circuit to ensure the safety of the equipment.
Advancements in Vacuum Drying Technology
◆ Automated Control Systems: Modern vacuum dryers are equipped with advanced control systems that can automatically adjust the drying parameters in response to real-time data from sensors within the chamber. This eliminates the need for manual intervention, reducing the risk of human error and improving process consistency.
◆ Enhanced Solvent Recovery: Many modern vacuum dryers incorporate solvent recovery systems that capture and recycle the solvents used in the drying process. This not only reduces waste but also lowers operating costs and environmental impact.
◆ Multifunctional Chamber Designs: To meet the diverse needs of researchers and industrialists, vacuum dryers are now available in a range of chamber sizes and designs. Some systems are even modular, allowing for the addition of additional features or chambers as needed.
Protein purification in vacuum drying oven
Although the laboratory vacuum drying oven does not directly participate in the separation and purification step of the core in the process of protein purification, it plays an important role in some specific situations, such as drying and preserving purified protein samples. The following are the parts of the protein purification process that may involve vacuum drying chambers and their general processes:
● Basic process of protein purification
Protein purification is a complex and delicate process that usually involves the following key steps:
Sample preparation: To ensure the integrity and purity of the sample, to avoid protein degradation and contamination of impurities.
Centrifugation: removal of large particles such as cell fragments and nuclei.
Preliminary separation: Using ion exchange chromatography, gel filtration and other technologies, according to the charge, size and other characteristics of the protein for preliminary separation.
Fine purification: Affinity chromatography, column chromatography and other technologies are used to further isolate and purify the target protein.
Verification: The purified protein was verified by SDS-PAGE gel electrophoresis and Western blotting.
● The application of vacuum drying oven in protein purification
Dried and purified protein:
After protein purification is complete, it is sometimes necessary to dry the protein sample for long-term preservation or subsequent analysis.
Vacuum drying oven can dry protein samples at low temperature and low oxygen environment, effectively avoiding protein denaturation and oxidation caused by high temperature.
During the drying process, the activity and stability of the protein sample can be ensured by controlling the vacuum degree and temperature.
Specific operation process:
Place the purified protein sample in an appropriate container, such as a petri dish or glass bottle.
Place the container in a vacuum drying oven and set the required vacuum degree and temperature.
Start the vacuum drying oven and begin the drying process. During the drying process, the drying degree of the sample needs to be checked regularly to prevent excessive drying leading to protein denaturation.
After drying, remove the sample and store it sealed in a dry, cool place.
● Precautions
Protein samples after drying should be analyzed as soon as possible or stored properly to prevent moisture or re-contamination.
In the whole process of protein purification, attention should be paid to the optimization and control of experimental conditions to improve purification efficiency and protein stability.
Cultural relics protection
Vacuum drying laboratory has significant application value in the field of cultural relics protection. The following is a detailed introduction to the vacuum drying laboratory in the protection of cultural relics:
The working principle of vacuum drying laboratory
Vacuum drying laboratory mainly uses vacuum technology and heating principle to accelerate the evaporation and discharge of water in materials by reducing air pressure and heating materials, so as to achieve the purpose of drying. In the protection of cultural relics, this technology can effectively remove the moisture in cultural relics and prevent cultural relics from being damaged by moisture.
The application of vacuum drying laboratory in cultural relics protection
Paper cultural relics drying
Paper cultural relics are susceptible to moisture, acidification and oxidation, resulting in reduced mechanical strength and even complete loss of preservation value.
The vacuum drying laboratory can dry paper cultural relics at low temperature, effectively remove water, while maintaining the original form and structure of cultural relics.
Especially for acidified paper cultural relics, vacuum drying technology can also be combined with deacidification technology, first remove the acidity of cultural relics, and then dry treatment, thus extending the preservation life of cultural relics.
Wood relics drying
After soaking in water for many years, wooden cultural relics are prone to shrinkage, deformation and cracking due to excessive moisture.
Traditional drying methods often lead to these problems due to local water loss too fast.
The vacuum drying laboratory can quickly remove the water in the wooden cultural relics at low temperatures, while maintaining its original form and structure, avoiding the occurrence of shrinkage, cracking and fracture.
Other organic material artifacts drying
In addition to paper and wood artifacts, vacuum drying laboratories can also be used to dry other organic material artifacts, such as fabrics, leather, etc.
These materials are easily affected by environmental factors such as humidity, temperature, microorganisms and so on to degrade or rot.
Vacuum drying technology can effectively protect these cultural relics and extend their preservation life.
The advantages of vacuum drying laboratories in cultural relics protection
Low temperature drying
The vacuum drying laboratory can be dried at low temperatures, avoiding thermal degradation and oxidation reactions caused by high temperatures, thus maintaining the original form, color and texture of the cultural relics.
Uniform drying
The vacuum drying technology can ensure that the drying process is carried out evenly, avoiding the shrinkage, warping and even cracks of cultural relics due to local too fast water loss.
Inhibition of microbial growth
The anoxic environment inhibits the growth and activity of microorganisms, reducing the risk of damage to cultural relics due to biodegradation.
Protection of the original nature of cultural relics
The vacuum drying process is carried out under the conditions of low temperature and hypoxia, effectively avoiding the chemical or biological reactions that may occur in the drying process of cultural relics, so as to maintain its original nature and structure.
Case analysis
In library and archive conservation, vacuum drying laboratories are widely used to dry damp ancient books and paintings. Through this technology, the original appearance of cultural relics can be restored and their preservation life can be extended. In museums, vacuum drying laboratories have also been used to restore flood-stricken artwork and archaeological finds. For example, for wooden cultural relics soaked in water for many years, vacuum drying can effectively prevent their shrinkage, cracking and fracture.
Cultural relics drying is a complex and delicate process, and different types of cultural relics need to pay attention to different problems when drying.
During the drying process, we should pay close attention to the changes of cultural relics to ensure that they are gradually dried in a safe and stable environment. At the same time, it is also necessary to develop personalized drying programs according to the characteristics and needs of different types of cultural relics, in order to protect the integrity and value of cultural relics to the greatest extent.
