Features

Laboratory Drying Oven, Digitmatic (70-640L)

Features of Laboratory Drying Oven, Digimatic (E-Version)

Circulation Air Flow System:

This feature involves a system that circulates air within the drying oven chamber. Circulation ensures even distribution of heat throughout the chamber, resulting in uniform drying of samples. It helps to eliminate hot spots and ensures consistent drying across all parts of the oven, which is crucial for obtaining accurate and reliable results.

PID Electronic Control Unit:

PID stands for Proportional, Integral, and Derivative, which are control algorithms used in feedback systems. The PID electronic control unit in your drying oven provides precise and stable temperature control. It continuously monitors the temperature inside the oven and adjusts heating elements accordingly to maintain the set temperature with minimal fluctuations. This ensures optimal drying conditions and enhances the reproducibility of experiments or processes.

Manually Air Outlet Chamber:

The manually adjustable air outlet chamber allows users to control the ventilation or airflow within the drying oven. By adjusting the outlet, users can regulate the rate at which moist air is expelled from the chamber. This feature provides flexibility in managing drying conditions, especially for sensitive samples or processes that require specific airflow rates to achieve desired results.

Quality Door Rubber Gasket Seal:

The door rubber gasket seal is an essential component that ensures an airtight seal when the oven door is closed. It prevents heat loss and maintains the internal temperature stability of the drying oven. A high-quality gasket seal also helps to prevent the ingress of dust, moisture, or contaminants from the surrounding environment, thereby protecting samples from potential contamination or external influences during the drying process.

Test Procedure

Laboratory Drying Oven, Digitmatic (70-640L)

  • Preparation of the sample: Ensure that the sample is properly prepared according to the requirements of the specific test or analysis being conducted. This may involve obtaining a representative sample, reducing it to an appropriate size, and any necessary pre-treatment.
  • Preheating the drying oven: Preheat the drying oven to the desired temperature as specified in the testing standard or procedure. This allows the oven to reach thermal equilibrium and ensures accurate and consistent drying conditions.
  • Weighing the sample: Weigh the sample using an accurate balance and record its initial mass. This measurement serves as the baseline for determining the moisture content or any changes in mass during the drying process.
  • Placing the sample in the drying oven: Place the sample in a suitable container or tray, ensuring that it is spread out evenly and not piled up to ensure uniform drying. Place the container with the sample inside the drying oven.
  • Setting the drying parameters: Set the desired drying temperature and time parameters on the oven’s control panel. These parameters may vary depending on the type of sample and the testing standard being followed. Start the drying process by activating the oven. The circulation airflow system within the oven helps maintain uniform heat distribution and efficient drying of the sample.
  • Initiating the drying process: Start the drying process by activating the oven. The circulation airflow system within the oven helps maintain uniform heat distribution and efficient drying of the sample.
  • Monitoring the drying process: Monitor the drying process closely, observing any changes in the appearance or condition of the sample. Periodically check the sample’s moisture content or mass at specified intervals to track the progress of drying.
  • Endpoint determination: Continue the drying process until the sample reaches a constant mass or until the desired moisture content is achieved. This is typically indicated by consecutive weighings showing no further decrease in mass or a specific level of moisture content as required by the testing standard.
  • Cooling and final weighing: Once the drying process is complete, allow the sample to cool inside the oven to room temperature before removing it. Weigh the dried sample again to determine its final mass.
  • Calculation of results: Calculate the moisture content or any other desired parameters based on the initial and final mass measurements of the sample. Follow the specific formula or calculation method outlined in the testing standard or procedure being followed.
  • Reporting results: Record all relevant data, including the initial and final mass of the sample, drying parameters, and calculated results. Prepare a test report documenting the procedure followed and the obtained results for future reference or analysis.
