Aluminum foil, clean

Aluminum Foil, Clean Aluminum foil without the usual lubricants on the surface. 

Tin foil (packaging) A term often used for aluminum foil. Aluminum foil supplanted tin foil for packaging in about 1910. See also Aluminum foil, clean. 

Normal laboratory glassware must first be washed and cleaned. It has to be rinsed with deionised water. The clean glassware is sterilised in an oven set at 200 °C for 1 1 hours. It is suitable to cover glassware with aluminum foil to maintain aseptic conditions after removing the glassware from the oven. If aluminum foil is not available, special heat-resistant wrap paper can be used. The sterile glassware must be protected from the air, which has micro-flora, or any contaminants. Avoid the use of any plastic caps and papers. Detach any labelling tape or other flammable materials, as they are fire hazards. 

Whole-body dosimeters are processed post-exposure as follows. The whole-body dosimeter is laid on a table covered with fresh aluminum foil and is sectioned into various pieces using a solvent-cleaned pair of scissors. The whole-body dosimeter is usually cut just at the knees to provide two lower leg sections, at the waist to provide an upper leg section, at the elbow to provide two lower arm sections, at the edge of each shoulder to provide two upper arm sections, and across the shoulders and down each side of the chest area to provide a front torso and back torso sample. The two-dosimeter sections from symmetrical parts of the body are combined to form one sample and wrapped in aluminum foil prior to storage. The upper leg, front torso, and back torso pieces are kept separate, and each is wrapped in aluminum foil prior to storage. 

Welcome to You Bet Your Grade. The secret word is dissolve. Say it slowly as you watch the cap liner in some vials dissolve into your nice, clean product and turn it all goopy. This can happen. A good way to prevent this is to cover the vial with aluminum foil before you put the cap on. Just make sure the product does not react with aluminum. Discuss this at length with your instructor. 

Clean staining dishes, forceps, and slide holders wrap them with an aluminum foil, and bake them at 350-400°C for approx 4-6 h. 

Place a clean sheet of aluminum foil on a bench top work area. Carefully remove each slide from the slide holder. Wipe remaining alcohol around the periphery of the tissue with Kim-wipe and place it on the clean sheet of aluminum foil.

Low and coworkers (.28, 29, 30) have pioneered the application of FT spectrometers to the observation of emission spectra from solid surfaces. An example taken from a study by Low and Coleman (29) is illustrated in Figure 13. Spectrum A shows the emission of a clean aluminum foil at 33°C. Spectrum B is of the same surface after it had been wiped with an oleic acid-coated paper and then wiped dry. Spectrum C is the same as B, but taken with twice the number of scans and twice the gain. The bands near 1700, 1650, and 1600 cm are attributed to the carbonylstretching frequency of undissociated acid, to the asymmetric O-C-O vibrations of the oleate ion, and to the symmetric O-C-O vibrations, respectively. Similar bands were detected at 100°C, as shown in spectrum D, indicating that the oleic acid had reacted with the aluminum surface to form an oleate.

After glassware is try, store inverted or capped with aluminum foil in a clean environment. 

All water samples were placed and kept in chemically clean, 1-gallon glass bottles, closed with a screw cap with aluminum foil insert. 

Care must be taken during fractionation of 1,5-cyclooctadiene and the bromocyclooctadienes, because contamination of the bromide with 1,5-cyclooctadiene leads to contamination of 1,3,5-cyclooctatriene with the diene. A 1-2-mL intermediate fraction effects clean separation. The distillation took the checkers 6-8 hr. The bromides are extremely light sensitive, turning yellow to red-brown quickly. To avoid product coloration all product receiving flasks were wrapped in aluminum foil. 

Cleaning Up Empty the chromatography column onto a piece of aluminum foil in the hood. After the solvent has evaporated place alumina and sand in the nonhazardous waste container. Evaporate the crystallization mother liquors to dryness and place the residue in the hazardous waste container.

For ternary system measurements, the two solids to be studied are first mixed to provide intimate contact. The minimum melting point for the solid-solid binary at atmospheric conditions occurs at the eutectic composition. A solid mixture of this composition is prepared in the expectation that a similar ratio of the components will be present in the liquid phase at the first melting point in the ternary mixture. The solid mixture is melted and stirred to obtain a homogenous liquid. Some of the liquid is drawn into a capillary tube. The remaining liquid is poured out onto a clean sheet of aluminum foil. After the binary liquid cools and solidifies, the thin sheet of solid material is broken up into "flakes" for loading into the view cell. 

The skin is cleaned and anesthetized as for other similar procedures, and lOmL of fluid is aspirated into a syringe connected to the spinal needle that is typically used. Sterile containers such as polypropylene test tubes or urine cups are used to transport the fluid to the laboratory. If a specimen is for the determination of the lecithin-sphingomyelin (L/S) ratio, the container is immediately placed in ice if it is for spectrophotometric analysis, the specimen should be transferred to a brown tube or bottle to prevent photodegradation of bilirubin. Alternatively the specimen container may be wrapped in aluminum foil. 

The glass dish is lined with aluminum foil, on which the tarnished silver cutlery is placed. The soda solution is poured in and left to stand for a few minutes (not more than 10). The cutlery is now washed with distilled water it is completely clean and shiny. The same effect is obtained when table salt is poured on to the tarnished cutlery and the latter wrapped in aluminum foil and rubbed hard. 

The contents of the cleaning bath are poured down the drain and the aluminum foil disposed of with the household waste. 

If a heat lamp is used, the crucible is placed on a clean, nonreactive surface, such as a wire screen covered with aluminum foil. The lamp is then positioned about 1 cm above the rim of the crucible and turned on. Charring takes place without further attention. The process is considerably accelerated if the paper is moistened with no more than one drop of concentrated ammonium nitrate solution. The residual carbon is eliminated with a burner, as described in the next paragraph.
