What Is a Laboratory Microwave Oven?
The Laboratory Microwave Oven removes moisture from samples through a rapid drying method. The unit is especially suitable for drying aggregate, soil and similar construction materials. Laboratory teams can also use it for conditioning and preheating suitable samples.
Moisture content directly affects many laboratory calculations. Therefore, operators must determine the wet and dry mass of a sample carefully. Microwave drying provides an important advantage when laboratories require faster results.
Rapid Moisture Content Determination
The operator first places the sample in a suitable container. Then, laboratory personnel weigh the container and sample using a precision balance. The sample is subsequently dried in the microwave for controlled intervals.
After each drying stage, the operator weighs the sample again. When the mass becomes constant, the drying process is complete. As a result, moisture loss can be calculated from the difference between the initial and final mass.
ASTM D4643-25 describes the determination of moisture content in soil and rock using microwave oven heating. The method provides a practical option when rapid results are required. However, excessive heating may affect the structure of certain materials. Therefore, the operator should carefully control the drying time and heating conditions.
Rotating Tray for Uniform Heating
The integrated rotating tray continuously moves the sample during operation. This movement helps distribute microwave energy across different parts of the sample.
More uniform energy distribution supports a controlled drying process. In addition, the operator can mix the sample at suitable intervals when required. This approach helps reduce localised overheating and promotes more consistent drying.
Compact 17 Litre Chamber
The unit offers a 17 litre capacity. Its internal chamber measures approximately 21 × 28 × 28 cm, while the external dimensions are 45 × 30 × 30 cm.
With a weight of approximately 11 kg, the microwave oven provides convenient benchtop operation. The unit also operates with a standard 220 V electrical connection. Therefore, laboratories can install it without requiring complex electrical infrastructure.
Applications in Aggregate and Soil Laboratories
Soil laboratories can use the Laboratory Microwave Oven for rapid moisture determination. Aggregate laboratories can also use the unit for fast drying of suitable samples. Furthermore, research and quality control laboratories can include it in preconditioning and sample preparation procedures.
ASTM C566-25 covers the determination of total evaporable moisture content in aggregate by drying. However, laboratories should always select the drying method and equipment according to the requirements of the applicable test procedure.
Fast and Practical Drying Solution
The LT-Go260 Laboratory Microwave Oven combines rapid drying, a rotating tray and compact dimensions in a practical laboratory unit. Its 17 litre chamber provides sufficient capacity for routine sample preparation and moisture control work.
As a result, laboratories can reduce processing time during daily testing. The compact design also makes the unit suitable for laboratories where benchtop space and operational efficiency are important.
