Uniform Suspension of the Clustered Triamcinolone Acetonide Particle
Figure 2
New suspensions methods using various instruments. Vortex mixer used in the experiments is shown (a). The arrowhead points to the site that vibrates, and for each suspension, the tube was fixed on the mixer using vinyl tape (arrow). Syringe and three-way stopcock circuit suspensions system is shown (b). Samples are first placed within one of the syringes. Processing is then performed by repeatedly pushing the sample between the two perpendicularly arranged syringes. Fluid travels via the three-way stopcock, with movement occurring as the directional arrows. Ultrasound washer suspension is shown (c). Tubes are mounted on a styrofoam float and placed within the water tank. Ultrasound vibrations cause suspension of the samples while they are floating on top of the water.
