HTVO-90 High Vacuum Oven with 90L 18x18x18″ Chamber, 900°C Max Temperature, Sliding Door, 5-Side Heating
The HTVO-90 is engineered for precise heat treatment of air-sensitive materials requiring controlled high temperature and vacuum conditions. Its spacious 18″x18″x18″ (90 liters) stainless steel chamber accommodates a variety of sample sizes while maintaining a tightly controlled environment. This oven is ideal for processes demanding uniform heating up to 900°C under vacuum levels reaching 10⁻⁵ torr, ensuring minimal oxidation or contamination during thermal treatments.
Temperature uniformity is achieved through five-sided heating combined with four layers of SS310 reflective plates inside the SS304 chamber, delivering ±2°C stability within a 12″x12″x12″ central zone. The sliding door design, equipped with water cooling, facilitates safe and convenient sample loading while preserving the vacuum seal. Integrated vacuum ports and gas inlet/outlet fittings support flexible vacuum and gas flow configurations, including options for turbo pump integration.
