BMG LABTECH instruments are German engineered to last a very long time, there is no such term as “planned obsolescence” at BMG LABTECH. However like all instruments, a BMG LABTECH microplate reader needs to be properly maintained to ensure that optimal results are achieved over the longest possible operation time. Therefore BMG LABTECH recommends that your microplate reader undergoes a periodic (annual, biannual) Quality Control and Preventive Maintenance (QCPM) evaluation. A QCPM can occur onsite or at one of our local distribution headquarters. A QCPM consists of a battery of tests to ensure that all parameters are within their optimal operating range as well as routine preventive maintenance of the instrument.
