Vacuum Ovens

1. Equipment Inspection - Before using your vacuum oven, be sure to check the entire product for damage including cracks, dents, or any other kind of visible blemishes that may render the item unsafe. Do not use the oven if any such damage is visible. Always be sure to check the oven's fittings for leaks, and seal threaded connections with TPU tape.

2. First Use - When using your oven for the first time, set the temperature to 300F and let the oven run for at least 1 hour. This will burn off any oil from the manufacturing process and will calibrate the thermometer for better accuracy.

3. Proper Use - HFS vacuum ovens are NOT explosion proof. Be sure to use in a well ventilated area, using proper filters and cold-trap systems to eliminate airborn solvents and flammables. Vacuum ovens require at least 6" of space on all sides for proper heat ventilation. It is normal for vacuum ovens to rise above the set temperature, then lower to it accordingly. If your samples are extremely heat sensitive please be aware of this.

4. Pay Attention - Never leave a vacuum oven unattended. Keep equipment away from children and pets. Be sure your chamber/oven is able to accept the amount of vacuum applied by your pump. Vacuum implosions can be fatal.
