  1) Technical data (according to DIN 12880)

Model 1445, Medium Vacuum Oven, Fully Programmable Watlow Temperature Control, Three Shelves, Includes RS485 Communication Capability, 1.7 Cu.Ft. (Also: Model 1480)

This unit is durably constructed with seamless welds and strong bracing. All SHEL LAB vacuum ovens are built with a stainless steel chamber for exceptional durability. We use solid brass vacuum valves with Teflon seats to prevent leaks. Our double plenum design meets CE safety requirements resulting in a cool outer surface.

The doors on these units have positive latch handles with spring-loaded glass to facilitate a good vacuum seal without hinge binds that shorten the gasket life. A selection of gaskets (for specific applications) and a small bench top footprint increase the versatility of these ovens.

SHEL LAB was the first to bring square vacuum ovens to the industry and we continue to offer innovative, top-of-the-line vacuum ovens. Our unique cross-flow ventilation forces inert gas to fill the entire chamber. To achieve required vacuum levels, users can choose from a 3/8 inch orifice or a KF25 fitting to withstand heavy use and minimize draw-down time. Maximum permitted end vacuum is 10 µ. Leak rate is 10 µ per hour.

The SHEL LAB Vacuum Ovens are equipped with silicone gaskets. While these gaskets resist a wide variety of temperatures and pressures, they can breakdown in the presence of solvents and acids. For solvent applications, we recommend using Buna gaskets. For acidic applications, we recommend using Fluorosilicone or Viton® gaskets.

The CE Oven Series incorporates the Sure Load shelf system, triple wall construction, easy to read microprocessor controls. Adjust the air exhaust from the chamber without putting your fingers near the heat source. Even at temperatures of 225°C the outer skin of this unit meets all CE requirements, meaning your application will stay hot but your workspace will not. The CE series ovens are CE approved.

This gravity convection oven provides a degree of uniformity comparable to most forced air ovens on the market. The 99 min 59 hr digital timer has an independent control so its use is optional. Once the timer expires the power is cut to only the heating elements. The CE family is our lastest installment of a product of Constant Thinking.

These units include:

• Sure Load Shelf Design
• Non-Tip Shelves
• Microprocessor Controls
• Suberb Temperature Control
• Cool Touch Damper
• Digital Timer to 99hr and 59 min
• CE Approved
• Warranty: 2 years

• Used for drying, baking, sterilizing, evaporating, heat treating, annealing and testing
• Quick run-up and recovery times
• Exterior has a hard, scratch-resistant hammer finish on a heavy steel double-wall construction
• Temperature is controlled by an automatic hydraulic or a bi-metal thermostat
• UL and CSA recognized
• Warranty: 18 months

Our high strength glass bottles are available in many size configurations to suit various hybridization applications efficiently. Manufactured of low beta emitting borosilicate, they reduce exposure to radioactivity. Exposure is further limited by the leak proof closure system. 

Blue Cap = Polyethylene With O-Ring Seal; Temp. Resistance: -40°C to +140°C
Red Cap = Polyethylene With Teflon Seal; Temp Resistance: -45°C to +200°C

The CE Oven Series incorporates the Sure Load shelf system, triple wall construction, and easy-to-read microprocessor controls. Users can adjust the air exhaust from the chamber without being near the the heat source. Even at operating temperatures of 225°C, the outer skin of this unit meets all CE requirements, so workspaces remain cool. 

The 99 hr 59 min digital timer has an independent control, so its use is optional. Once the timer expires, the heating elements turn off while the blower continues running to cool the samples inside the oven. 

Whatever the application, these forced air ovens deliver precise uniformity, air distribution and the peace of mind expected from the SHEL LAB brand. All of the SHEL LAB CE series ovens are CE approved. The CE family is our lastest installment of a product of Constant Thinking.
