Making Liquid Herbal Extracts or Tinctures Instructions prepared by Suzanne Zick‚ ND‚ MPH Extraction is the process of obtaining the constituents of an herb by means of a suitable solvent. By this process‚ the indigestible woody fiber (cellulose) and other insoluble material are left behind‚ so that only the soluble parts of the whole herb end up in the preparation. The solvent(s) that are chosen depend on the constituents present in the herb. The descriptions and directions below apply to when

and Combustible Liquids? Put simply‚ flammable and combustible liquids are liquids that can burn. The real difference lies within their flash point range‚ or lowest temperature at which vapours of the material will ignite when supplied with an ignition source. Flammable and combustible liquids are utilised in most workplaces‚ from manufacturing to retail and service entities. To ensure the safety of property‚ people‚ and the environment‚ both flammable and combustible liquids need to be handled

LAB 02: Measuring and Dispensing Liquids Introduction Pipetting is one of the most important and basic skills when it comes to experimental science. Good pipetting skills allow an individual to put trust in his or her results‚ prevent waste of materials‚ and assure reproducibility of results. In order to correctly pipette liquids‚ the volume range must be first determined. p1000 micropipettes have a volume range of 200 - 1000 uL‚ p200 micropipettes have a volume range of 20 - 200 uL‚ and p20 micropipettes

Data Analysis The pH of a liquid affects the brownness of a banana. This experiment was started by the question‚”Does the pH of a liquid affect the browning time of a banana? “ The hypothesis was “that the lower the pH the less brown a banana will turn.”. The experimental group was bananas placed in liquids with varying pH levels : lemon juice‚ lime juice‚ vinegar‚ baking soda water‚ alkaline water‚ and distilled water. This experiment’s dependent variable is the number of spots each banana has

Which Liquid Dissolves Sugar Free LifeSavers Quickest? The purpose of my experiment is to find out which liquid‚(orange juice‚ water‚ Coca-Cola‚ or Sprite)‚ dissolves Sugar Free Life Savers the quickest.I think the Sprite will dissolve the Life Saver the quickest because it has the highest acidity‚ with ph levels reaching 2.4. The ph scale ranges from 0 to 14. Battery acid reaches 0 on the scale. 7 is considered neutral. Sprite has a ph level of 2.4. Coca-Cola has a ph level of 2.5. Orange juice
