The BP-125 from Microwave Research and Applications, Inc. is an economical and compact laboratory microwave ideal for tissue staining, antigen retrieval, chemical processing, sample ashing and other general laboratory heating tasks. The user can program the process controller for a temperature profile for the sample. The process controller then monitors the sample temperature and will increase the temperature of the sample at the programmed rate and then hold the sample at a desired temperature for any length of time. Because the processing is controlled by feedback of the sample temperature, it provides consistent and repeatable processing regardless of small line voltage fluctuations, sample size differences, starting sample temperature, microwave component temperature and age of the microwave. These factors often are the largest cause of inconsistent processing when using microwave ovens designed home use.
The BP-125 laboratory microwave has a corrosion resistant stainless steel cavity and housing. It has a powered cavity exhaust to remove obnoxious or corrosive fumes and prevent their build-up inside of the cavity. Heating uniformity is achieved by a mode stirrer system and gives extremely good heating uniformity. There is no turntable to break and they take up valuable cavity space and move samples during processing making it difficult to instrument.
The standard microwave safe temperature probe is easily replaced by the user without tools. The actual thermocouple is imbedded within a heretically sealed 1/8” diameter x 3 inches long stainless steel tube. For further corrosion resistance PFA coating of the probe is available. Other thermocouples configurations and a non-contact infrared (IR) temperature sensor are available.
The programmable process controller measures the sample temperature and compares it to the thermal profile the user has programmed into the process controller. The process controller can be programmed for a sample temperature ramp rate, process temperature and process time. If the sample temperature is too low, the process controller turns the microwaves on, thus increasing the sample temperature to match the programmed protocol. If the sample temperature is too high, the controller turns the microwaves off, reducing the sample temperature. The controller continues these evaluation steps to keep the sample temperature following the programmed protocol. The BP-125 laboratory microwave produces up to1000 watts of power for quick heating of larger samples.
The standard process controller can be programmed with a temperature ramp and the desired “soak” temperature and time. Place your sample into the microwave cavity and insert the thermocouple in the sample. Start the process and when complete, the microwave power will turn off and there is a visual indication that the cycle is complete.
