Feasibility trails were carried out by melt granulation method. Method: Drug was passed from 40# sieve. Weigh accurately drug‚ polymer and other excipients. Wax was melted at 60-65°C. After that drug and other ingredient were added to wax and mixing of drug and wax was done. Prepared lump was passed from 10# sieve. Granules were dried at 40°C. Lubricant was added to granules. Granules were compressed to prepare tablets. Table 4.6: composition of trail F1 and F2 Ingredients F1 F2 Metformin Hydrochloride

In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to

The procedure provided was used with only one change and one correction. The procedure calls for 3 or 4 drops of water to dissolve the dye on the M&M candies but 7 drops were used for each pair of candies because there wasn’t enough water in 4 drops to efficiently dissolve the dyes; the YouTube video for this step from the procedure also showed an application of about 7 drops. The traced solvent front line in this case was not a straight line but a curve with a maximum on 3.2in and minimum on 2.48in

A hospital is a faced paced dynamic environment involving private and personal life changing events to the patients it serves. Patients depend on the doctors‚ nurses‚ and laboratory technicians‚ all persons that will be involved in their care‚ to have the training and experience to provide the highest quality of care and safe‚ effective treatment. Publication of the report “To Err Is Human: Building a Safer Health System” in 2000 has brought to public attention to the numerous errors that can

Whats the relation between milk and corn? Purpose:To identify the chemical relationship between corn and milk and how one can be turned into the other. Hypothesis: If I test corn for nutrients then it will test possitive for starch‚lipids and fats but negative for protein because it only consist of those nutrients and not the other. If I test milk for nutrients then it will test possitive for lipids‚protein‚and fats but negative for starch because it consists of those nutrients.

Abstract The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided‚ and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer and the DCM was then decanted. After washing the anhydrous calcium chloride pellets with more DCM‚ the solvent was evaporated‚ leaving

Practical Work Nº2: “Different methods to control osmosis” Aim: observe and test the process of osmosis through different kinds of methods: the weigh (potato)‚ the density (beetroot) and under the light microscope (onion). Hypothesis: according to the encyclopedia definition osmosis is the diffusion of a liquid (most often assumed to be water‚ but it can be any liquid solvent) through a partially-permeable membrane from a region of high solvent potential to a region of low solvent potential. Thus

Aim: Investigate the effect of different temperatures and chemicals including various pH levels‚ alcohol and detergent on the cell membrane structure as well as function. Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane.
