To determine the degree of flocculation, flocculated suspensions were made using potassium dihydrogenphosphate(0.004 mol) as flocculating agent. Protamine Zinc-Insulin suspension. The administration of drugs in pure form... How to Make a Calibration Curve in Excel. release, supernatant clarity, and capillary suction time (CST) measurements on the flocculated mixtures. These aggregates can undergo sedimentation by settling down to the bottom of the liquid. phase)is dispersed in the vehicle (external phase). The slow sedimentation prevents the liquid from being entrapped in the sediment. It is more stable What are commonly used reducers of Zeta potential? Advantages: Should settle slowly, The particle size should remain constant, Should pour readily and evenly, physically and chemically stable, resistant against microbial contamination and good organoleptic properties. DETAILED DESCRIPTION OF THE INVENTION . Such effects can influence the nature and stability of flocculated suspensions. Except with biologicals you move it from one side to the other gently. Home » Science » Chemistry » Physical Chemistry » Difference Between Flocculated and Deflocculated Suspension. Based on the Proportion of Solid Particles. Features expected in Pharmaceutical suspensions. Think Wealthy with Mike Adams Recommended for you United States Patent 6268356 . Procaine penicillin G, Insulin Zinc Suspension. Flocculated Suspension: The volume of sediment in a flocculated suspension is high. Pharmaceutical Miller el til. Flocculated suspensions. Flocculated suspensions not be elegant because they are difficult to remove from bottles or vials & on transferring from the bottle the floccules remaining sticking to the side of the bottle. The structures of magnetic iron oxide suspensions were visualized using cryogenic scanning electron microscopy (Cryo-SEM) and video-enhanced light microscopy (VELM) under shear, elongational, and rotational flows. They provide advantages to deliver higher doses and insoluble or poorly soluble pharmaceutical ingredients can be administered.

It Difference Between Flocculated and Deflocculated Suspension, What is the Difference Between Flocculated and Deflocculated Suspension. Even after the formation of the sediment, the supernatant of this suspension will still have a cloudiness. Colloidal suspension (< 1 micron) Coarse suspension (>1 micron) Nano suspension (10 ng) 1.3 Advantages And Disadvantages. 1. Reversibly flocculated suspensions often display time-dependent viscosities or “thixotropy”. Flocculated suspension . should be such that the formulation to be easily removed from the container. The weting agent, polysorbate (not more than 0.1 … The sedimentation volume were determined by keeping 50 ml of each suspensions in stoppered measuring cylinder and stored undisturbed at room temperature.
