I don't know how to sterilize my equipment, because right now I'm using rubbing alchohol.  I don't know what type of specimens I should use either, and 1 more thing... what should I put in the petri dish[Super Scientist]?

get yourself some pond water, theres more stuff to look at in there that just about anything else.\n\nRubbing alcohol is ok for sterilising, unless your using stuff thats potentually dangerous it will do.\n\nIn your petri dish you put Agar, it's jelly stuff u can buy it  in sachets, its made from seaweed, when u are mixing it up with water u add a drop of nutrient solution, normally specific to what your trying to grow.  The find yourself some bacteria or mold and put them in the petri dish, cover it up and watch.

You don't give us which lab you are doing, so results would be hard to find..  For general information, do a good web search with the name of what you distilled.  I don't think you will find everything you want, but there is a large number of websites on the general subject.

Some bacteria/bacterial spores can survive boiling temperatures; in order to provide enough latent heat to ensure sterilization, it is necessary to raise the temperature to 121 degrees C (and 15 psi).\n\nAs for the length of time, consider how the measurement of antiseptic effectiveness is often measured; decimal reduction time. This is the amount of time it takes to reduce a bacterial population by 90%. Even if the decimal reduction time is quite short (as it is in an autoclave), you must still leave things in there for several decimal reduction times in order to ensure sterility.

Sonication is hard with gram positives. The heat required often destroys the thing you are trying to extract.\n\nIt is going to have to be strong and you are best testing the equipment and probes you have to get the best answer. Try using dilution plating or protein estimation assays to work out the efficacy of disruption. It will almost certainly be in the region of minutes at high powers though,

Just keep it clean don't put alcohol or vinegar on it! It'll hurt like hell.

Take a (Warm) bath with Epsom salts\nDON'T USE A SOLDERING GUN!!!\nUSE Preparation H instead.\n\nGO TO The hospitals ER room or a MEDICAL CLINIC!!!

Any fluid that will keep the air out but which won't corrode the specimen.\n\nStrong alcohol such as vodka is good or perhaps something like methylated spirits or while spirit. Avoid household bleach or vinegar as they're likely to be too corrosive.\n\nAs spiders have a hard external skeleton, it is also possible to preserve them by drying them out... you often see this in butterfly collections. Just use a long stainless steel pin and pin the body of the spider to a small piece of wood or thick cardboard. Place the specimen in somewhere warm, dark and dry for a couple of weeks. Don't cover it in anything that will keep moisture in or it will rot. The specimen will then be perfectly preserved (but very brittle - so take care!)

Maybe this will work:  Innoculate the inside of a zip-lock storage bag with your germ specimen. Then seal it and place it in a refrigerator. Scrub hands with betadine sugical scrub for 15 minutes.  Maintain sterile field and technique while putting on sterile gloves.  Keep hands gloved between contacts with the inside of specimen bag, which you will do nine times. Put on a new pair of gloves after each contact, always maintaing sterile precautions.  Hazardous waste management procedures would work well, I think.  Good luck.

Infection is always a risk. I've had mine done for years and have never had a prob. Go to a clean reputable place and ask if they disinfect their tools. (I know you don't want to seem like a snob asking this, but your health is more important)

Distill the water. The WATER comes out of the tubes, not the salt.\n    As for testing, just drink a little of it. Do you *LIKE* it?\nNo? Well you better make sure that you don't put it back in the same cup you used for collection.\nOK the water will still pass an electric current through it if it has any impurities. Completely pure water will not.\nUnless you use more than around one volt, in which case the bubbles you see escaping will be hydrogen and oxygen. That means you've gone too far with the testing part.

This is how I do it:\n\nViva Kitchen Tissue + Rubbing Alcohol\n\nRubbing alcohol is antiseptic as well as reacts with the oils to remove them.\n\nViva is soft! (I also use a velvet cloth sometimes)\n\n\nCommercially, \nThere are special tissues available for this; I bought one for $6.99; was good for a year then the sheets dried out. The above solution works good so I didn't by another one.\n\n\nTO CLEAN INSIDE:\nCompressed air; I spray it once in a while on the fans from the outside to avoid the laptop to overheat.

You might try different solvents. Such as carb cleaner or lacquer thinner. I'd try on a part you won't see when the telescope is fully assembled. If all else fails use a wet sand paper and re paint. The factory finish is usually a baked on type that lends itself well to cleaners. You might also think of using a green scrubby. Although this might dull the finish. You might then wish to recaot with a gloss or satin clear designed for metal. Good luck in your endeavor.

Wear your PPE (Personal protective equipment). The safest way would probably be to dispense it in a fume hood, with secondary containment (e.g. inside a container with boundaries). You'll want the secondary containment to contain something that can neutralize the base, such as a weak acid. This is for the liquid.\n\nThe solid sample should be dispensed in a fume hood, using a scoopula to transport the sample after it has been poured out.

Alcohol does NOT dissenfect anything. IT is a solvent that is used to clean the surface...has a very low surface tension. In cleaning, most bacteris are wiped away, but alcohol does NOT kill bacteria. Bacteria cannot 'grow' in concentrations much above 10% alcohol, but that doesn't mean they are dead..just dormant. There is no useful purpose in using alcohol of any higher concentration.
