vacuum drying oven

Laboratory drying ovens are standard equipment in most laboratories and are used for high forced volume heat convection applications. Regardless of the set temperature, they can provide uniform heating for the entire device. Generally speaking, most laboratory ovens are manufactured at temperatures ranging from ambient temperature to about 300°C. Ovens with higher operating temperatures are generally used for professional applications in the fields of physics, material processing, and electronics. Other uses include annealing, die bond curing, drying, polyimide baking, and sterilization. We will discuss the topic of vacuum drying, which is the use of vacuum and heating to remove large amounts of absorbed water or other solvents from the product. The liquid to be removed is usually a natural part of the product, a residue from a previous operation, or used to dissolve, mix, or apply chemicals as part of the process design. Although freeze-drying is carried out using vacuum in the drying process, the freeze-drying process is not involved here. A vacuum drying oven is a very cool and useful tool. You can use this tool for multiple purposes like removing moisture, degassing, baking out, and preventing reactions. There are many products that need to be dried in a vacuum oven, such as medicines, implantable medical devices, satellites and other space hardware, temperature-sensitive products with retained moisture, epoxy resin; it can be dried by vacuum, food analysis (allowed for packaging food Moisture) essential oils extracted from plants. The working principle of the vacuum drying oven: To dry, the moisture must change from liquid to gaseous. After the vacuum furnace reduces the pressure, this reduces the temperature at which the water evaporates from the liquid state to the gas state. After that, this pressure change causes the water to evaporate, thereby drying at a lower temperature. Under vacuum, water always boils at a lower temperature. Benefits of the vacuum drying oven: As mentioned earlier, the vacuum drying oven has many advantages. Because the oxygen content is very low, vacuum drying does not require an oxidation process. The next advantage is continuous drying without hard skin on the top. Another advantage is that it absorbs moisture from hard-to-reach corners and crevices. The evaporated and vacuum dried fluid can be recovered later. Another benefit of vacuum drying is the gentle way, because this drying will not even disturb light and powdery items. The most important benefit of vacuum drying is that it reduces the risk for workers. It likes to prevent the exhaust of hazardous solvents and chemicals from being trapped instead of entering the surrounding air. Vacuum drying ovens are used in many industries, such as aerospace industry, medical industry, electronics, etc. If you want to know more about vacuum drying, please click XCH Biomedical.

Use cases of laboratory ovens: Chemists, biologists, engineers, and researchers use laboratory ovens for various purposes. These ovens involve drug stablity testing, technology development, forensics, electronic testing and material processing. The laboratory oven heats the material by convection. The material is placed in a separate chamber instead of the main chamber. It can prevent the material from changing, but the heat is enough to dry or solidify. The oven has double walls with a layer of insulating material (usually air) between them to save energy. The inner wall is made of a material with low thermal conductivity. The outer layer is made of metal. They are equipped with hot air circulation fans to achieve even heat distribution. Laboratory ovens in industry Before buying a laboratory oven, you should consult an industrial oven manufacturer to find out which type of oven you need. When looking for the perfect laboratory oven, consider the needs of your industry. Various types of laboratory ovens have a variety of functions that have been continuously developed over the years. Therefore, reliable and powerful equipment has been improved year by year to meet the requirements and needs of laboratories. Customers can choose from a range of models, whether the oven is for quick investment or is equipped with numerous programs with multiple stages. Mechanical convection ovens, vacuum drying ovens, gravity ovens and high-temperature ovens can help in the pharmaceutical industry and laboratories. On the other hand, multi-purpose ovens and forced ventilation ovens are used for glassware drying, while vacuum ovens can dry fragile materials and remove flammable solvents. Benchtop and laboratory ovens are ideal solutions for small spaces and when small batches of loads need to be disinfected, dried or cured. However, when looking for a new oven for your laboratory, what qualities and functions should you look for? Price—Although there is certainly an argument against making choices based purely on price, it is important to understand that laboratories usually operate with minimal capital and may not have a lot of idle capital. Scale-This is usually just the main problem for laboratories that lack space or worry about energy consumption. It should also be noted that temperature control is more difficult in larger ovens. Temperature range-this is the most important attribute and refers to the highest reliable operating temperature above the ambient temperature. The most common ranges are 250ºC, 300ºC, 400ºC, etc. Temperature uniformity-this is another important feature, which means that every point in the oven is at the same temperature as the temperature shown on the display. Some manufacturers will adopt stricter conformance standards than others. Energy consumption-Today, it is possible to buy ovens that minimize power consumption. This can save you thousands of dollars throughout the life of the device. Efficiency is a complex quality, which is based on many different factors. Ergonomics-Although laboratory oven controls are not too difficult to use, they should be easy to view and access on the front panel and should not require the operator to bend over or reach. Jiangsu XCH Biomedical Technology Co., Ltd., with professional knowledge and experience, can help you find a laboratory oven that meets your needs.

How do you determine the right lab drying oven for your lab and application? With so many lab ovens on the market, how do you find the perfect oven for your needs? Here are some tips to help you: 1. Select the oven type according to your application. Mechanical convection drying oven Designed with a motor and fan to circulate air for even heating and faster drying times - ideal for drying and heating of samples requiring greater accuracy, multiple samples and high moisture content. Application General Heating - Baking, heating and drying glassware and rubber Sophisticated Heating - Bitumen testing, conditioning, digestion of proteins and starches, drug metabolism, electronic aging, epoxy and plastic curing, serum protein analysis, stability chamber and QC batch testing, sterilization, suspended solids assessment and vulcanization studies. Gravity Convection Drying Oven No need for a fan to ensure gentle, natural circulation of the warm air moving upwards - ideal for disinfection, drying and other applications requiring subtle airflow. Application Use when the powder or substance will be disturbed by the airflow generated by the fan. Ideal for simple heating such as baking, drying, conditioning, preheating, aging and curing. Vacuum drying oven A vacuum is created to remove moisture from the sample faster than using ambient temperature. Ideal for tightly controlled processes such as drying, vacuum embedding, electroplating and semiconductor processing. Application Heat in an oxygen-free atmosphere to prevent sample corrosion or scaling. Drying, low temperature drying, aging testing, moisture determination and chemical resistance studies. Ideal for pharmaceutical/food drying and electronics Plant vacuum oven Provides higher vacuum levels for faster and safer extraction. Great for botanical and cannabis applications. 2. Match the oven size to your material. Choose an oven that is neither too small nor too large. Consider the size of the sample and how many you need to put in the oven at one time. Choose a smaller one that might fit your space but not your sample. Getting the maximum oven when you don't need it will consume too much energy and you will lose cost efficiency. 3. Use the oven at your desired temperature. Maximum oven temperatures range from hundreds to thousands of degrees. Choose the oven temperature based on the desired temperature for your materials. Like size, you don't want to choose a size with a higher temperature range if you don't need it. You will waste money and energy. 4. Choose the oven with the best thermal insulation. Lab ovens often run at high temperatures for long periods of time and consume a lot of electricity. Choose an oven with the best thermal insulation to reduce heat transfer rates. This will prevent the generated heat from leaking out of the chamber, minimizing energy waste and saving energy costs. 5. Look for ovens that are easy to clean and maintain. Being able to clean and maintain your oven is very important. Failure to do so could undermine the lab's push to advance your science. Look for ovens with rounded corners for easy cleaning, and stainless steel components and interior construction to extend the life of your oven. Also, look for trays and racks that can be removed quickly, as well as a larger door so you can access the inside of the oven when you need to clean it. A leak has occurred. 6. Make sure the oven you choose has reliable safety features. Prevent fire and protect your valuable samples from overheating. Choose an oven with a built-in over-temperature thermostat so that if the temperature exceeds a set temperature, the oven will shut down. Other features to consider include temperature excursion alarms, overcurrent protection, and automatic start-up after power loss/recovery.

Many applications require laboratory drying ovens to remove moisture from samples. They are a necessity in many environmental, clinical and biological laboratories and forced air and come in many different forms. This blog will explain what laboratory drying ovens are and what they are used for. Standard Drying Oven vs Laboratory Drying Oven Standard drying ovens are designed to remove moisture from the oven chamber to dry samples as quickly as possible. This type of oven brings fresh, dry air into the chamber while removing moist air. This dries the sample quickly, however, it requires an airflow system that can extract moisture from the air. Laboratory drying ovens are designed to heat samples only. This means that the oven will continuously circulate the same air around the chamber and provide heating only. Both oven options are effective and used to meet different requirements. The Importance of Laboratory Drying Ovens Laboratory drying ovens are an invaluable aspect of everyday workflow, and their use can range from simple glassware drying to complex controlled heating applications. Laboratory drying ovens provide temperature stability and reproducibility for all application needs. Gravity convection ovens work on the basis of the rising temperature distribution of warm air. These laboratory drying boxes do not use fans to actively distribute air indoors and have very low turbulence. Mechanical convection ovens use an integrated fan to actively move air from the room, creating an even temperature distribution in the room. This means optimum temperature uniformity and highly reproducible results. Uses of laboratory drying ovens Laboratory drying ovens can be used to control the temperature and keep it safe. They are also frequently used in testing and drying biological samples and in forensic laboratories to assist in the development of fingerprints. In addition, laboratory drying ovens can be used in environmental studies to dry samples before and after weighing to determine the moisture content of the samples.
