About VACUUM OVEN

Vaccum oven : A highly versatile compact oven with a large useful working area, it can be operated at atmospheric or reduced pressure by using reduced pressure, the oven enables heat sensitive materials to be dried at low temperature. Alternatively, more stable samples may be dried more rapidly at higher temperature, without fan circulation. This oven is also particularly useful for controlled atmosphere heating (e.g. curing of resins under nitrogen or reduced oxygen conditions) since the inner chamber is sealed. It may also be suitable for solvcent removal work providing that adequate exhaust & ventilation are provided for the oven and room respectively.

Construction : The external case is tough stoved epoxy based powder coated steel, to with stand the most demanding working conditions. The vacuum chamber is made of thick jointless 304 grade stainless steel sheet provided with one shelf, which carries a mercury in glass thermometer which can be viewed through the 150mm wide window by large area heaters strapped to its outer surface. Glass fiber insulation maintains safe, low outer case temperatures. The chamber is closed by a 6mm thick toughened glass plate sealing on to a silicone rubber gasket. The door closures are screw threaded catches which ensure an excellent vacuum tight sealing.Vacuum controls : Reliable inlet & exhaust valve is fitted. These are situated near the front corner of the oven for convenient connection to a vacuum pump. Vapour trap or exhaust. A vacuum gauge is fitted showing vacuum pulled from 0 to 760mm. Temperature control : Oven temperature is controlled by capillary type thermostat form ambient to 250°C with in +1°C

Advanced Vacuum Performance

Engineered for precise applications, the VO-28L Vacuum Oven achieves a stable vacuum level of 0.1 MPa, thanks to its robust chamber and high-quality vacuum gauge. The oven supports laboratory research and product processing by ensuring contaminants are removed efficiently under controlled environments, leading to improved results and reliable reproducibility in various laboratory processes.

Superior Temperature Control and Uniformity

Equipped with a microprocessor-based PID controller and a nichrome wire heater, the VO-28L delivers accurate temperature regulation, ranging from 50C up to 250C. The temperature is evenly distributed within the chamber, maintaining a uniformity of 1C, which is critical for sensitive laboratory and research procedures that demand consistent heating and reproducibility.

Robust Construction and Enhanced Safety

Crafted using polished stainless steel for the interior and powder-coated mild steel for the exterior, this vacuum oven ensures longevity and resistance to corrosion. Features like over-temperature protection, mineral wool insulation, and a transparent observation window provide extra safety and convenience, making it ideal for rigorous daily laboratory use while guaranteeing operator safety.

FAQs of VACUUM OVEN:

Q: How does the vacuum oven achieve uniform temperature distribution inside the chamber?

A: The VO-28L utilizes a nichrome wire heater combined with a microprocessor-based PID controller to ensure precise and consistent temperature control. The highly efficient mineral wool insulation and polished stainless steel interior further aid in delivering a uniform temperature with a variation of only 1C throughout the chamber.

Q: What safety features are integrated into this vacuum oven to protect both samples and users?

A: This vacuum oven includes over-temperature protection, which automatically prevents the oven from exceeding set limits. Additionally, the toughened glass door, powder-coated exterior, and mineral wool insulation enhance overall safety and durability during operation.

Q: When should a vacuum oven like VO-28L be used in laboratory settings?

A: The VO-28L is ideal for processes requiring dehydration, degassing, drying, and thermal treatment of sensitive samples under reduced pressure. Its precise temperature and vacuum control make it suitable for pharmaceuticals, electronics, research labs, and material testing environments.

Q: Where can the vacuum oven be installed and used safely?

A: This vacuum oven is designed for use in laboratory environments with adequate ventilation and stable electrical supply (220 V, 50 Hz). It should be placed on a sturdy surface, away from moisture, and locations prone to chemical exposure or excessive dust for optimal operation and safety.

Q: What are the benefits of using a transparent toughened glass door and removable trays in this oven?

A: The transparent toughened glass door allows effortless observation of samples without heat or vacuum loss, minimizing disruptions to the process. Removable stainless steel trays enhance sample handling, accommodate a variety of items, and make cleaning and maintenance simple.

Q: How is the oven prepared and transported to ensure safe delivery?

A: Each unit is securely packed in a wooden box, safeguarding the vacuum oven from physical shocks and environmental factors during shipping. This ensures the oven arrives in optimal working condition, ready for immediate installation and use.
