The DS30, DS45 and DS60 constant-temperature ovens use natural convection and are suitable for general sample drying, material pre-treatment, quality inspections, research testing, school laboratories and process heating in factories. Select a chamber size and model based on sample dimensions, capacity needs, operating temperature, whether forced airflow should be avoided, and the installation environment. Confirm the final selection against the sample, test purpose and quality-control process.
Natural convection
Natural-convection heating is suitable for general sample drying, constant-temperature heating, material pre-treatment and quality-control testing.
Two temperature ranges
Choose an operating range of 40℃–210℃ or 40℃–300℃ according to the sample’s heat resistance and drying purpose.
Three chamber capacities
The DS30, DS45 and DS60 provide capacities of 30 L, 72 L and 150 L. Choose according to sample quantity, chamber space and placement requirements.
How to choose a constant-temperature oven
For general sample drying, material pre-treatment, quality inspection, laboratory sample handling or factory process heating, first confirm sample dimensions, batch quantity, target temperature, drying time, whether forced airflow should be avoided, available power and installation space. The DS30 suits smaller loads, the DS45 is a mid-capacity option, and the DS60 suits larger samples or loads. Confirm the final model against the samples and operating process.

Frequently asked questions
Q1: How should I choose between the DS30, DS45 and DS60?
Start with chamber capacity, internal dimensions, sample quantity and available space. The 30 L DS30 suits smaller loads, the 72 L DS45 is a mid-capacity option, and the 150 L DS60 suits larger samples or higher throughput. Confirm the choice using sample dimensions, batch quantity and workflow.
Q2: What applications suit a constant-temperature oven?
It can support general sample drying, material pre-treatment, quality inspection, research testing, school laboratories and factory process heating. Confirm suitability based on sample material, target temperature, processing time and drying purpose.
Q3: How does a constant-temperature oven differ from a forced-air oven?
A constant-temperature oven uses natural convection, which creates less air movement. A forced-air oven circulates heated air with a fan and is commonly used when airflow is needed for drying or heating. Check the model specifications and sample conditions for the actual differences.
Q4: How do I choose between 40℃–210℃ and 40℃–300℃?
Choose according to the sample’s heat resistance, drying purpose and maximum operating temperature. For lower routine temperatures, consider the 40℃–210℃ version; for samples or processes requiring higher temperatures, consider the 40℃–300℃ version. Verify the available configuration and specifications against current product information.
Q5: What information should I provide before requesting a quotation?
Provide the sample material, dimensions and weight; batch quantity; usual and maximum temperatures; processing time; whether natural convection is required; power supply; and installation space. This helps identify a suitable capacity and model.
Specifications are summarized from the available product information. Confirm the temperature range, power configuration, accessories, options and supplied version according to the model and application needs.
