Vacuum Drying Oven YR06623 // YR06626

The Vacuum Drying Oven YR06623 // YR06626 is a laboratory instrument designed for drying, degassing, curing, and thermal treatment processes of materials sensitive to heat and oxidation. Thanks to its natural convection system and the ability to operate under controlled vacuum, these ovens allow drying at lower temperatures, preventing the degradation of chemical, pharmaceutical, biological, and electronic samples.

This series integrates high-precision PID controllers, with temperature resolutions of up to ±0.1 °C and excellent thermal stability (±0.5 °C), ensuring reproducible results even during prolonged processes. Models YR06623 and YR06624 incorporate advanced digital displays and inert gas injection options, making them ideal for applications requiring protected atmospheres. Meanwhile, models YR06625 and YR06626 offer a robust and efficient solution with mechanical vacuum indication, maintaining an optimal balance between performance and cost.

Manufactured with an internal chamber made of SUS304 stainless steel, high-efficiency eco-friendly thermal insulation, and double tempered anti-explosion glass, these ovens ensure safety, durability, and easy cleaning. With chamber volumes ranging from 23 L to 55 L, this range is suitable for research laboratories as well as industrial and quality control environments. On the international market, the price of a vacuum drying oven with these characteristics varies depending on capacity and automation level, positioning it as a cost-effective investment for laboratories seeking long-term precision and reliability.

Frequently Asked Questions (FAQ)

What applications are vacuum drying ovens recommended for?
They are mainly used for drying heat-sensitive materials, powders, granules, electronic components, pharmaceutical products, and chemical samples that must not be exposed to oxygen.

What is the difference between models YR06623/24 and YR06625/26?
Models YR06623 and YR06624 feature more advanced PID control, digital vacuum display, and inert gas injection options, while YR06625 and YR06626 prioritize operational simplicity with a mechanical vacuum indicator.

What temperature range does the equipment reach?
All models operate from ambient temperature +5 °C up to 250 °C, with excellent thermal stability.

Does the oven require an external vacuum pump?
Yes, the oven must be connected to a compatible external vacuum pump to achieve the required vacuum level depending on the application.

Advantages and Disadvantages

Advantages

• Efficient low-temperature drying thanks to vacuum operation.
• High thermal precision with PID control.
• Corrosion-resistant stainless steel internal chamber.
• Multiple capacities and configurations to meet user needs.
• Enhanced safety with double tempered anti-explosion glass.

Possible Disadvantages

• Requires an external vacuum pump (not included).
• Higher initial investment compared to conventional drying ovens, offset by superior performance and process quality.

Field Use of the Product

In daily practice, vacuum drying ovens are used in pharmaceutical laboratories for drying active ingredients, in the electronics industry to remove moisture from sensitive components, and in research centers for the thermal treatment of specialized materials. The operator programs the temperature and drying time, adjusts the vacuum level, and, if necessary, introduces inert gas to protect the sample. The result is a faster, safer, and more uniform process than traditional drying methods.

Recommendations

• Always use a vacuum pump suitable for the chamber volume.
• Do not overload the trays to ensure uniform heat transfer.
• Perform regular maintenance on the sealing system and controller.
• For sensitive applications, consider models with inert gas injection.
