Orders subject to lead time of 2 months from the UK manufacturer

This Vacuum Oven was previously manufactured by Sanyo Gallenkamp and branded ' Gallenkamp Vacuum Oven '. Since 2004 it has been manufactured in the UK.

In 2011 The Oven was upgraded to have an electronic DIGITAL p.i.d.controller which replaces the previous hydraulic thermostats.

Main Features:

•     COMPACT SIZE, LARGE LOAD (31 LT) CAPACITY
•     POPULAR 'GALLENKAMP' DESIGN NOW UPGRADED
•     DIGITAL PID CONTROLLER FOR EASY AND FASTER
•     TEMPERATURE SETTING WITH OVER TEMPERATURE ALARM INDICATION
•     INDEPENDENT OVER-TEMPERATURE SAFETY PROTECTION
•     EASY TO READ VACUUM GUAGE
•     HIGHLY VERSATILE OVEN FOR ATMOSPHERIC OR REDUCED ATMOSPHERE OPERATION
•     SUITABLE FOR SOLVENT REMOVAL
•     TOUGH STEEL CONSTRUCTION WITH STRONG DOOR CLOSURE
•     TOUGHENED GLASS WINDOW WITH POLYCARBONATE SAFETY SCREEN
•     FRONT MOUNTED PUSH-ON CONNECTORS

The Digital Vacuum Oven features a spacious rectangular chamber with toughened glass viewing window and shatter-resistant safety screen

Temperatures up to 200C are possible via the PID digital electronic controller. An independent temperature safety circuit protects sensitive samples from over-heating.

A vacuum gauge and two needle valves with tubing connectors are conveniently sited on the front panel. Two shelves and an operating manual complete the package

Tough Construction
The outer case is tough, stoved epoxy-polyester painted steel, to look good even under the most demanding working conditions.The vacuum chamber is a robust light alloy casting supplied with two shelves and three shelf positions. The chamber is heated by large area heater panels strapped to its outer surface

Glass fibre insulation maintains safe, low outer case temperatures. The chamber is closed by a 12.5mm thick toughened glass plate sealing onto a silicone rubber gasket. This glass plate is mounted onto the door by 4 spring-loaded pins to ensure an excellent, even seal to the chamber. Door closure is achieved via a strong and positive twist action latch.
As an extra safety precaution, a 4mm thick shatter resistant polycarbonate safety shield covers the door window.
Temperature Control


An electronic digital PID controller allows for easy and faster temperature setting with integral over-temperature alarm indication.

Temperatures up to 200C are possible via the PID controller. An independent over-temperature safety circuit protects sensitive samples from over-heating.

By using reduced pressure, the Vacuum Oven enables heat sensitive materials to be dried at low temperatures. Alternatively, more stable samples may be dried more rapidly at higher temperatures, 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 solvent removal work, subject to adequate exhaust and ventilation conditions being provided for the oven and room respectively.
Vacuum Controls

Reliable, needle type inlet and exhaust valves are fitted. These are situated near the bottom front corner of the oven for convenient connection to a vacuum pump, vapour trap or exhaust. The serrated nozzles accept flexible vacuum tubing of 10-12mm bore. A vacuum gauge is fitted showing vacuum pulled, from 0 to 1000 mbar.
