Top 6 Signs that You Should Service or Replace Your Lab Oven

		Ovens should have a regular maintenance schedule to avoid unscheduled downtime and potential loss of product. Components such as gaskets, elements, blowers, etc. should be replaced or verified before they become a problem. Temperature calibration should be checked on a routine basis.
		When your process outgrows your oven’s capabilities. Ovens have very different performance characteristics such as temperature uniformity, temperature range, capacity, heat-up time, and recovery time. If your oven’s performance does not match your process requirements, then it’s time to upgrade.
		If your oven is more than 7 years old, chances are it has parts that are obsolete and impossible to purchase, which could result in excessive downtime. It is better to replace the unit early and reduce the risk.
		When the warranty period has expired. Repairs on units that are out of the warranty can be costly. When a unit is in need of repair and is out of warranty, it may be more economical to buy a new unit.
		Your process may produce hazardous exhaust. Baking certain materials in an oven can produce flammable vapor and/or obnoxious odors. Upgrading your oven to a vented system can do more than make a better smelling workplace, it can also bring you into compliance with government safety regulations.
		Any time you have issues such as slow to reach temperature, temperature variation, noises, reduced airflow, or problems with door alignment and gaskets, you should service or replace your lab oven.

Top 5 Questions You Should Ask When Buying a Lab Oven

	What temperature range do you require? (Does the product have reserve temperature capacity?)
	What accuracy and uniformity does the product have? (Will my sample be damaged or will my experiment only function in one “sweet spot”?)
	Are interior chamber space / weight of my sample and floor space in the lab a match to application and lab?
	Do I need any computer interfaces, alarms or safety devices on my oven?
	Are accessories like data loggers, viewing windows and modifications like access ports available from the manufacturer to suit my specific needs?
