Embodiment 1
[0094] Example 1: Transferring fluid into an absorbent container
[0095] adopted with figure 1 A series of tests were carried out with a sampling device of the invention similar to that shown. The barrier 10 is composed of a porous glass filter, the absorbent material 11 is composed of a hydrophilic resin, the sphere and the support are polypropylene. The sampling surface consisted of water-soaked gauze in small petri dishes. Color the water with food coloring. The ball was rolled 1-2 times on the surface and the fluid was observed to saturate the absorbent resin 11 rapidly. Because of the translucent nature of the device and the colored fluid, this extraction can be confirmed visually. The device was weighed before and after the test. It is also shown that the extraction of fluid is proportional to the volume of the absorbent resin. A device filled with 100 mg of hydrophilic resin will absorb approximately 45 mg of fluid, and without absorbent resin, the device will ab...
Embodiment 2
[0096] Example 2: Delivery of a sample onto the surface of a sphere
[0097] Under the premise of the following improvements, using the same figure 1 A series of tests were carried out with a sampling device of the invention similar to that shown. The device is free of absorbent resin and glass filters and is segmented behind the sphere, allowing access to the inner surface of the sphere.
[0098] (a) Biopsy of meat
[0099] The device is rolled over moist gauze containing a biopsy section of fleshy tissue. Rolling causes tissue fragmentation. The sample is delivered into the device by rolling on the gauze surface. Using adenylate kinase as a marker enzyme, for biological activity, the inner face of the sphere was enzymatically sampled. The inner sphere is contacted with 20 μl of fluid. The fluid was then removed and analyzed for the presence or absence of adenylate kinase using luciferase bioluminescence. Roll the device on moist gauze without a meat biopsy section and...
