Abstract
Use of microwave equipment for fast food preparation and for speeding up chemical reactions e.g. in diagnostic testing is wellknown. However in all such uses the known equipment provides a very uneven heating effect, thereby limiting the value of the method. The present patent application describes an improved type of microwave equipment, in which an even effect is obtained by the use of a combination of microwaves of different wavelengths. The equipment according to the invention includes one or more microwave sources, controlled individually or jointly, emitting microwaves of a two or more wavelengths, e.g. in the form of distinct single wavelengths, White Noise, Square Waves.
Claims15
A method for immunohistochemical testing comprising the steps of:
- placing a sample to be tested on a sample slide;
- treating the sample;
- placing the sample and slide in a microwave cavity;
- uniformly energizing the microwave cavity using microwave energy source means including at least three different wavelengths;
- and
- energizing the cavity for a predetermined specified reaction time,
- whereby samples are energized consistently with the proper level of microwave energy despite the variations in heating normally found in microwave heating cavities.
A method for immunohistochemical testing comprising the steps of:
- placing a sample to be tested in a sample slide;
- treating the sample;
- placing the sample and slide on a small shelf in a microwave cavity;
- uniformly energizing the microwave cavity using microwave energy source means including at least three different wavelengths;
- and
- energizing the cavity for a predetermined specified reaction time,
- whereby samples are energized consistently with the proper level of microwave energy despite the variations in heating normally encountered throughout microwave heating cavities.
Improved microwave equipment comprising:
- a microwave source emitting waves of more than one frequency;
- and
- means for supporting an immunohistochemical sample for uniform irradiation by said source.
