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.

You can use something called a sand bath or a water bath (for the wax not you!) You can also keep it in a crucible and in a microfurnace. Your lab should have these facilities.

do you mean HCL then you would have to get it through a company where making it would be cost effictive or ur school's chem lab

Here's what I would suggest:\n\n1.  Do your homework!  Make sure you are familiar with the procedures you intend to follow.  Starting in without having prepared yourself is a recipe for disaster.\n2.  Familiarize yourself with the laboratory.  Make sure you know where the fire extinguishers, emergency showers, eyewash stations, spill cleanup kits, and exits are located.\n3.  Take note of where chemicals are stored.  Acids, bases, and flammables should all be stored separately.  If you take something out of one of these storage areas, be sure you put it back where you found it.\n4.  Always, always wear your PPE (personal protective equipment).  This includes apron or labcoat, goggles or safety glasses with side shields, appropriate gloves when working with chemicals, face shield if working with particularly toxic or otherwise dangerous chemicals, long trousers, a long-sleeved shirt if you're wearing an apron, and sturdy shoes (no sandals!).\n5.  Always work in a properly ventilated laboratory hood.  Your lab hood should have a face velocity of at least 100 ft/sec for working with most organic chemicals.\n6.  This is the most important safety precaution of all.  If you are not sure how do something safely, ASK.  Ask a professor, ask a supervisor, ask a lab TA, ask SOMEBODY.  If you don't get an answer that you feel will allow you to work safely, then don't do anything.  Work safely or not at all.

Call your city sanitary waste department.  They usually have a place you can take hazardous materials....

Well, if you were capable, you could possibly extract or distill the dye from a jug of antifreeze.\n\nBut there aren't any common household chemicals you could mix up in the sink to make a green fluorescent dye.

Your question isn't really complete - the NaOH needs someting to react with.\n\nFor example:\n\nNaOH is used with lipids to make soap.\n\nNaOH + HCl -> H2O + NaCl

They're not available commercially. You have to purify them in a lab.

Normally I just wipe it off with hexane. But if I really want to destroy the silicone, I just dip it at least overnight in a KOH-Ethanol bath. That's just lots of potassium hydroxide dissolved in ethanol. Be careful as it is very corrosive and can cause blindness if it gets into your eyes. Wear goggles and use gloves.

If you are from the philippines, chances are it's methanol. It's cheap and convenient to use (in terms of burning and handling in lab classes). Just be careful. Avoid inhalation, ingestion, and skin contact. It is known to be highly toxic.

It is used to contain the chemicals in the lab !!!

You should get the MSDS sheets for the chemicals that you use, try invitrogen.com this is the best advice without more details on the techniques you're using.\nThere are two techniques I've used, one is detachment using trypsin/EDTA and the other is scraping the cells off the side of the flask. In both methods there is little danger from the tools you use, more danger is posed by the cells themself. If you're using an established cell line, get the details on it from www.atcc.org if not, be extra careful!

The only way I would suggest is just give some bribe to the person who is analyzing your water sample. If you can't manage that then email to me on ammyjhon@yahoo.com since there are hundreds of other loopholes to get out of it from Govt Agency like (Pollution Control Board).

Run it empty with one cup vinegar.  That should solve your problem.
