The VWR Sheldon 1490 Large Vacuum Oven is a high-capacity, precision-controlled drying system designed for laboratories and production environments requiring efficient, contamination-free heat treatment under vacuum. With a generous 4.5 cu ft (127 L) chamber, this oven delivers uniform heating, rapid drying, and precise vacuum control, making it ideal for sensitive materials that cannot tolerate oxidation or high thermal stress.
Manufactured by Sheldon Manufacturing, Inc. (also known as Shel Lab), the 1490 combines durable construction, accurate temperature regulation, and reliable vacuum performance — making it a trusted solution for pharmaceutical, chemical, electronics, and materials research applications.
Large Capacity Chamber – Spacious 4.5 cu ft stainless-steel interior accommodates large samples, trays, or multiple small batches.
Vacuum Operation – Enables drying and degassing at reduced pressure to protect heat-sensitive materials and prevent oxidation.
Uniform Heat Distribution – Advanced heating elements ensure even temperature throughout the chamber.
Temperature Range – Operates from ambient + 10 °C to 260 °C (500 °F) with exceptional stability.
Digital PID Controller – Provides precise temperature regulation, easy programming, and reliable repeatability.
Heavy-Duty Construction – Reinforced door gasket and double-wall insulation maintain vacuum integrity and energy efficiency.
Safety & Reliability – Equipped with over-temperature protection, independent control safety limits, and an easy-to-read LED display.
Clean, Corrosion-Resistant Design – Seamless stainless-steel interior resists chemical damage and simplifies cleaning.
Vacuum Range – Operates down to 10⁻² Torr (typical) depending on the vacuum pump used.
