A.Medication Scales There are 3 types of drug scales, namely: Scale Type : -Rough gram scale : load power 250 grams to 1000 grams, sensitivity 200 mg -Fine gram scales : load power 100 grams to 250 grams, sensitivity 50 mg -Milligram scales :load power 1o gram to 50 grams, sensitivity 5 mg Load power is the maximum weight that can be weighed.Sensitivity is the maximum additional weight required on one of the weighing plates, after both have been filled with maximum load, causing the weighingneedle to swing no less than 2 mm for every dm of needle length. Caption 1. Scale base board 2. Button to adjust the height of the scale 3. 1. Earrings indicate the upright position of the scales 2. Earring base indicating the uprightness of the scales (waterpass) 4. Scale needle 5. Scale 6. Scale support lever 7. Center knife or center knife. 8. Hand knife 9. Hand scales 10. Balance adjustment button/nut. 11. Scale plate Weighing 1. Check whether all the components of the scale/balance are in their proper place, by matching the numbers on the components. 2. Check that the position of the scale is parallel/even, as can be seen from the positionearring ( 3.1) with earring base (3.2) must be correct. If it is not correct, we turn the button (2). 3. Once again we check whether it is in place. If so thenThe scale will lift and you will see whether the plate is balanced or onesided. If it is not balanced, we can turn the nut (10) left or right according to the balance, so that the balance is balanced.positionlever (6)We have lifted or turned the knives (7) and (8). 4. After that, we place the parchment paper on the two weighing plates, lift the lever (6) to check whether the scales are balanced. When it is balanced, then weighing the ingredients can begin. 5. How to weigh ingredients: a. Solid materials such as powder, wax etc. are weighed on parchment paper b. ½ solid ingredients such as vaseline, adeps, are weighed on parchment paper or in an evaporating cup. c. Liquid ingredients can be weighed on a watch glass, evaporator cup or directly in a bottle or container. d. Thick liquid ingredients such as belladon extract and hyosciamy extract are weighed directly, while ichtyol is weighed on parchment paper previously smeared with liquid paraffin/vaseline. e. Oxidizing agents (Kali Permanganas, Iodine, Argenti Nitras) are weighed in a weighing glass or in a closed watch glass.Materials weighing less than 50 mg are diluted (discussed in the Pulvis chapter) C. Volume Measuring Tools 1. Measuring cups are used to measure liquids to be made or liquids taken, for example 100 ml of water. 2. Goblet / beaker glass for dissolving ingredients by stirring with a glass stirrer, can also be used to make mucilage amyli 3. Erlenmeyer is used to dissolve materials by shaking or shaking gently and is used as a measuring tool (low level of accuracy) D. Tools - Compounding Tools and Other Glassware 1. Mortar and stamper, used to grind and mix ingredients. 2. A spoon can be used to scoop out solid ingredients from the bottle, for liquid ingredients you can use a dropper or pour it directly carefully, while for semi-solid ingredients (thick extracts and fats) you can use a spatula. 3. A plastic/mica film spatula is used to unite, clean powder or ointment and put it in a container. 4. Evaporating cups (from porcelain) are used as weighing containers, to evaporate or dry liquids, melt or mix more than 1 ingredient. 5. Watch glasses/watch glasses and weighing bottles for weighing volatile, subliming materials and liquids that should not be weighed with parchment paper. 6. Infusion pot for making infusion solutions. 7. The pill board/pillen plank is used to roll pills, cut the pills, then round them with a pill rounder. 8. Sifter, a tool used to sift materials according to the degree of fineness of the powder 9. The funnel is used for filtering by placing filter paper on top of the funnel, cutting the filter paper round approximately 1 cm below the surface of the funnel. 10. Stirring rod Used to stir liquids 11. Capsule Filler Tool for filling capsules manually/by hand.
