Lab Ovens: Invaluable to numerous heating application

Drying Oven Lab Ovens Vacuum Oven

Laboratory ovens are used in a wide array of heating applications such as drying, sterilization, testing, and more. This analytical instrument is considered to be invaluable to numerous heating applications across pharmaceutical, chemical, foundry, automachines, and other industries. 

Generally, lab ovens are classified into 2 types, convection type and vacuum type ovens. The most common ovens in the industry have forced air-circulation function, high thermal efficiency, and can save energy. The use of forced ventilation ovens are capable of drying samples evenly. This type of oven gives minimal machine noise, smooth operation, temperature control, easy installation and maintenance.

Convection ovens heat samples through natural or forced circulation of hot air while vacuum ovens utilize vacuum pumps to remove air during heating procedures. These systems are usually easy and efficient to operate. Here are the basic steps in operating laboratory ovens:

  1. Place the samples inside the drying oven then close the door. 

  2. Turn on the power switch

  3. Set the required temperature and working time. 

  4. The oven will now run the working condition you set. Once the experiment is done, turn off the power switch and remove your samples. 

  5. Note that if the operating temperature is too high (generally above 70°C) be sure to wait until the equipment has cooled down or use a dedicated tool for removing the items. 

Below we have included precautions, safety practices and reminders to help you maintain the working condition of your ovens. Additionally and more importantly, to ensure you safely operate your experiments and prevent any fire and health hazards. 

First, make sure to place your oven in a clean, indoor, moisture-proofed, and damp working room to prevent any corrosion. Also, the oven’s space allocation should be far away from walls and should be more than 2 meters. 

Inspect your oven’s voltage requirement. The required voltage of small ovens is 220V while large ovens have a required voltage of 380V. Additionally, make sure to install sufficient capacity power knife, choose the right power lead, and have good grounding wire. 

Another important thing to remember, before placing your samples into the oven, connect the power supply then open the switch first. For ovens with blowers, keep the blower open during heating and thermostatic process, otherwise the temperature uniformity may be disrupted and may damage the heating element. Afterwards, adjust the oven’s temperature that suits your sample. 

Keep in mind that dry samples should not be arranged in dense manner. Do not place your samples in the bottom of the board (heat plate) as this will affect the air cycle within the oven. Also, prohibit baking flammable, explosive items, and volatile and corrosive items.

Once you are done with heating your samples, keep in mind to power off the unit before opening the door. Also, never touch the samples directly with your hand and always use a dedicated tool or wear gloves for protection to avoid accidental burns. 

The laboratory oven industry structure has become increasingly rich over time with the rapid development of today's scientific and technological progress. Through years of industry research and development in the electronic production market, the demand for technological advancements in drying equipment continues to increase.
