How much does a test tube cost?

Or how about a distilling setup?

My high school chemistry teacher had to use her own money to buy a distiller. Turns out she bought it from a city auction. In a previous life, it was used to make crystal meth.

Wow, either your teacher is a douche or your school is poor. At my public high school we never had such ridiculous policies.

LOL, your HS really poor or something?

No, it's a way to make sure that HS students, who are not, as a whole, the most responsible demographic, have some incentive not to screw around in chemistry class. You break it, you buy it. That way they don't have a bunch of teenagers abusing lab equipment.

It's just a way to encourage people to be more careful.

That said, it didn't stop me from breaking a thermometer (while trying to pull it out of one of those rubber stoppers) and ending up with the broken end jammed into my hand. I can still remember the dawning realization right after it happened that I had yelled, "Son of a BITCH!" when it pierced my hand and the teacher was standing immediately next to me.

You were more concerned that you cursed than that you poisoned yourself with mercury?

i actually laughed out loud at this.

I think they should have that policy. Too many dumb kids screw around and break stuff that can be expensive so it makes people be a little more careful and take responsibility if they aren't.

I can't remember for sure but I think we had this in HS science classes although if you were a nice kid and broke something minor, the teacher probably wouldn't make you pay to replace it. Although I remember pulling the thermometer out of the rubber thing was usually a pain and got broken more easily. I don't think I ever broke anything though.

ROFL 8/10. Nice.

At the high school level it's more likely to be an alcohol one.

QFT...who covers the time the school now has to go through to replace this. There is a lot of red tape for a teacher to get anything ordered and if she does it herself some parent is going to cry out they are trying to profit from their students.

I'd jus tgo buy a test tube and give it to her. NO way I'd pay for something I can replace on my own for far far less.

 

[rezinn]

It depends on what kind of test tube it is. I've seen anywhere from 500 tubes for 25 dollars to $50 per.

hahaha chinex.

I'd worry about putting stuff like that over heat.

May be a liability issue in that.

 

[ChefJoe]

Nah, they're < $0.20 each last I bought a pack. You should buy your own replacement and pretend nothing happened if they want $12 each. When we run columns in labs and collect samples in tests tubes we don't wash them because it costs more in time/acetone than it costs to replace the test tubes.

Now, the labs I TA for have a test tube modified with a vacuum side-arm that costs a bit more... I could see that going for $10+.

I second this.

Walk in with the 100 tubes, hand her one, then drop the other 99 on the floor.

Yea distilling setups are expensive.
We had to put like a $35 dollar deposit + sign a form saying we'd pay for it if we broke it for Organic Chem lab.

i order a lot of things from fisher scientific (TMO), you'd be amazed at how much they cost, even with a columbia discount

buying singles is expensive, they are about $1 each in bulk case.

i should go buy some TMO since they make so much money, i had to buy one of these:

and then buy really expensive water:

The glass are all flint, which means you cannot put them over a flame or heat anything in them.

- these are the 20 for $2 kind

I dunno about the chinex ones, but they're more expensive.

Been running experiments with membrane-bound well plates that cost almost $25 apiece and have to disposed after each use.

Test tubes are cheap by comparison...

I don't know about 20 cents a piece if they are pyrex unless they are very small...you can buy the standard size in bulk though and pay about twice that for 50-100 of them. You can also buy student packs especially geared for schools where you have to buy your own glassware.

Plain glass can be had for probably a nickle a pop for a small test tube, good for things outside heat and cooling...but not necessarily chemically inert/proof.

Tell her to show you the invoice where they cost 12 bucks.

read the tread skippy. We already covered that replacement cost is not usually what the item 'price' is. Someone has to go fill out paperwork and crap to get the damn thing especially at a school
