Dry Chemistry (also known as Dip Stick) refers to a diagnostic format where a test pad is bonded to a support structure such as a plastic strip for ease of handling the test pad for exposure to the test sample and read out. The test pad is impregnated with an analyte, which when exposed to a test sample, will change color or some other physical property which can easily be seen or measured with a reader. One of the most well-known applications of Dry Chemistry technology is that of urine testing.
Dry Chemistry tests take on other formats such as simple pads with impregnated chemistry such as for spore testing or multi layered devices. Lateral flow would be an example of a multi layered device where several overlapping impregnated layers are used. Typical applications for Dry Chemistry are for medical, agriculture, veterinary, and water testing. Water testing can include: waste water, boiler/cooling water, pool/spa water and drinking water. Typical measurements would be related to chlorine, bromine, pH, hardness, etc. associated with the use and treatment of water.
The challenge in the Dry Chemistry marketing is that there are many different formats used for a wide range of applications. The process most likely will include:
- Cutting to individual strips
- Placing the strips into Bottles
By combining the BioJet technology either using independent XYZ systems or a Reel to Reel, Autolaminators, and Cutting/Slitting Systems, BioDot can automate the Dry Chemistry Process.
The use of dry reagents along with impregnation of strips to which the specimen is added.
Additional Information ...
The application of dry chemistry in the field of biomedical technology is it can be used for well-patient, in mobile health services, in health clinics, in critical care testing in hospitals and also in polyclinics. The well-known application of this technology is for urine testing. Dry chemistry is also known as dip stick, which works where a text pad is bonded to plastic strip or any kind or similar support system, this support system provides an ease for handling the test pad, which expose the test sample and displays the result.
This dry chemistry test can also be taken using formats like simple pads with impregnated chemistry, which is generally used for multilayered devices or for spore testing. In case of multilayered devices we can consider the example of lateral flow where different overlapping impregnated layers will be used. Some of the typical application of this technique apart from medical field includes agriculture, water-testing and veterinary.
There are different formats available in dry chemistry with wide range of applications. Typical process of dry technology includes dispensing, lamination, slitting, re-lamination, cutting to individual strips and the process of placing the strips into the bottles. The precision of dry chemistry process is unbeatable. Analysts have rated this system as superior system compare to conventional system of testing. The flow of process includes:
- Cut or Singulate
