Cover area with disinfectant soaked-paper towels or with dry disinfectant. Allow a 20 minute contact period. Wipe down any contaminated stationary equipment or furniture with disinfectant. Use forceps, tongs, or broom to remove broken glass and other items; place in sharps container or red bag. Remove towels and re-clean area with disinfectant solution.
Added 2-3mL of liquid household bleach solution and stirred; solution turned orange. 5. Dipped cotton swab into the salicylic acid hydrolysis solution and wrote a message on a blank piece of flat, white paper and allowed it to dry. 6. Laid the dried message paper on several layers of paper towels for the visualization step to keep the developer solution from soaking on the work surface and surrounding materials.
Then, using the pipette fill drop one drop of dish soap into both cups to act as a surfactant or “wetting agent”. Next we have to draw the gases out of the spongy mesophyll tissue and infiltrate the leaves with the bicarbonate solution. To do this, open your syringe and place ten of the leaf disks in one syringe and ten in the other. Once that is complete, take the syringes and fill one with 5cc’s of bicarbonate solution and fill the other syringe with 5cc’s of water (make sure all leaves are suspended and aren’t already floating. Now we have to create a vacuum in the syringe to draw the air out of the leaves.
Materials * Blood smear (On the slide with having well-feathered edge.) * Alcohol Acetone (Fixative solution) * Eosin solution (fluorescent red dye) * New methylene blue (Organic staining agent) * Staining rack (To place solutions) * Bottled or running water (To rinse excessive solutions) * Absorbent paper (To remove or absorb excessive solutions) Steps of the procedure 1. Dip the slide into the alcohol acetone 3-5 times as the speed of second and remove the excessive solution with a paper towel. 2. Dip the slide into Eosin solution for 7 times and remove the excessive solution with a paper towel.
Sit the child down and put on a pair of disposable gloves. Gently pull down the lower eyelid and any visible foreign body removed with either a clean wet piece of tissue or a small piece of wet gauze. If this doesn’t work, pull the upper eyelid over the lower lid and try to flush it out with tears. If the foreign body still remains in the eye try to wash the eye with clean water by positioning the child’s head over the sink or bowl with their eye open, facing the bottom of the sink or bowl. Using a plastic cup try to pour water on the eye from the tear duct outwards.
These are placed under the top lip, between the cheek and the gum and let it dissolve), and a spray which is held up-right as close to the mouth as possible, hold it a close to the mouth as possible and spray, then close the mouth immediately. Do not swallow. Side effects of Nitroglycerin are: headache, upset stomach, rash, dry mouth, flushing or feeling very warm suddenly, dizziness, blurred vision, chest pain (agnia) and fainting. Nitroglycerin is used along with other drugs to treat Congestive Heart Failure and heart attacks. Congestive Heart Failure (CHF) happens when the heart’s inablility to strongly pump blood through the heart causes the fluid called congestion to buildup in the lungs and other body tissues.
Use the 1.0mm opening for 1.6mm fiber. Also trim the Kevlar to the ‘C’ length using the electrician style scissors. * Using the marker pen and the template card provided, measure and mark the buffer strip length as shown on the template. * Using the buffer strippers, strip off the buffer in at least two pieces. * Using a dry, lint-free wipe; Remove any remnants of the protective coating on the fiber after stripping the buffer.
Title Ink Chromatography Lab Background Information and Research 1. An ink chromatography is a way to separate a mixture. It uses solvents to separate the dyes that are used to make the color which is why there are more colors on the paper than what you start with. Paper chromatography has a variety of uses here are three that pertain to chemistry and biology. Paper chromatography can be used in separating amino acids and anions, RNA fingerprinting, and testing histamines and antibiotics.
Place a funnel on the top of the buret and slowly add 5g of dry alumina. When all of the alumina has been added, rinse the inside of the buret with additional petroleum ether to flush down any alumina that may be stuck to the sides. Add another 1-cm layer of dry clean sand on top of the alumina. Drain the solvent from the column until the solvent is at a level just above the top of the sand. The column is now ready for the addition of the mixture to be separated.
