The tube oven has a temperature range of up to 1100 °C and can fit 26mm diameter tubes. Temperature regulation is done by a Lindberg/Blue UP150 controller.

• read safety notes below
• Keep the components clean and do not use tubes that are not assigned to you
• wear gloves
• Make sure to mark or label your tube if you wish to keep it clean and keep it in the cupboard
• Indicate whether samples are loaded or not
• Check the specifications of the tube and boat before usage, make sure your tube and boat are suitable for your process (operating temperature)
• Place all parts in the small boxes near the oven

Outer diameter: 26mm
Length: between 55cm and 65cm

Operating temperatures of boat and tube material:

• Pyrex: 500°C (greenish color when viewing the edges)
• Quartz: 1000°C
• Al2O3: 1700°C

• high temperature
• pressurized gas cylinders

• Always lock the oven when a process is running.
• Let process cool down to 50°C before handling any components.
• No organic solvents on the table when a process is running.
• Work with clean tubes

Do not attempt to change cylinders or connected equipment, always consult with a technician.

• check that your tube and sample boat have a higher operating temperature specified than your process temperature
• load sample and connect tube adaptors
• double check reducer is closed
• open oxygen cylinder (make sure there is enough oxygen for you proces)
• set 1 bar on secundary pressure gauge
• set desired flow rate with needle valve
• setup heater program and start (see below on how to use the temperature controller)

• if you operated in single setpoint mode: turn off oven manually
• wait until oven temp is below 50°C
• close cylinder, keep flow on until pressure on primary and secundary pressure gauges is 0.
• close reducer and needle valve
• take out sample and put aluminium foil on parts to keep them clean

You can operate the temperature controller in two modes:

• single setpoint mode: the controller will go to the desired temperature and maintain the temperature indefinitely, you have to turn the oven off manually
• programming mode: the user can enter a series of setpoint and time values, the controller will follow the sequence.
