Walter Maxwell, Service Manager For 22 years Maxwell Instrumentation has specialized in the sales and service of atomic absorption spectrophotometers (AAs) and inductively coupled plasma spectrophotometers (ICPs). We have service contracts and highly trained service engineers available to serve our customers' needs. Our company services many different manufacturers of instruments such as Perkin Elmer, Instrumentation Laboratory, Thermo Jarrell Ash, Thermo Unicam, Varian and Buck Scientific. Maxwell Instrumentation has customers shipping us their electronic drawers, circuit boards and complete instruments for diagnosis and repair. Ted Fuller, Electronics Engineer This possible because we have a complete electronics shop and service center equipped with sophisticated diagnostic and repair equipment and a highly trained electronics engineer. Shipping costs are usually much less than on site travel charges and we can turn it around in a couple of days.
