Top 5 Signs That You Should Service or Replace Your Microwave Digester

	Corrosion is visible inside the cavity—this compromises the integrity of the cavity, may cause arching, and can cause microwave leakage.
	Strange noises—Trust your ears, if you hear something that is not normal then it’s probably not and should be investigated.
	Poor results—If you get poor results from a proven method.
	Temperature not following program—If your unit cannot follow a program as it has in the past, this could be a sign of low power output and should be checked by a service professional.
	Not heating—If your unit is not able to heat even a few hundred mL of water, then it should be serviced by a trained professional.

Top 5 Questions You Should Ask When Buying a Microwave Sample Preparation System

	What is the system’s maximum microwave power output? Microwave energy heats substances quickly to high temperatures. The higher the temperature, the faster and more completely substances are digested. Extractions also need sufficient power, as some solvents can act as a heat sink and are difficult to heat.
	Can the system monitor and control every vessel? Temperature and pressure monitoring and control are extremely important. Inadequate safeguards can result in damaged vessels and equipment, and a lack of temperature and pressure control can pose a safety hazard to lab personnel.
	How many samples can be processed per run? Though the number of samples processed is dependent upon your laboratory’s needs, planning for growth is always a good idea.
	Does the company offer free applications support? Do they offer dedicated, direct service support and local factory-trained field service technicians? Dependable applications and service support are essential since you never know what may go wrong.
	How user-friendly is the system? As with many instruments, if a system is very complicated to operate, it generally becomes either a glorified shelf to store things on or a headache to those having to operate it. The easier a microwave system is to use, the better off you will be. Also make sure the vessels are easy to handle and set up.
