Hi all,

Does anyone know where I could buy some sodium fluoride......ASAP? In the Newcastle area.
My teacher wants some for tomorrow.................I have phoned a few pharmacies with no luck.
Otherwise she'll have to wait...............

Hi all, We need to purchase some new dynamic trolleys. Apparently there are wooden (we have those at the moment, very old), plastic and metal types. Has anyone purchased any recently, or which ones, in general, do you recommend getting? Appreciate your thoughts.... :thumbup: \:D/ Also, looking at pu...

Thanks Lyn and Merilyn,

I actually had a bright thought (for once!) and I googled the molecular weight of tartaric and made up a 0.1M solution.
It was for investigating science.......just reactions

Hi all,

I need to make a tartaric acid solution.........should I just use a "spoonful" to 250 or 500ml of water???

Thanks...........

Hi all,

Posting for a friend.
Toronto high needs a labbie for 6 days from Friday 22 March to Friday 29 March. Contact Julie, 49591788.

Ha Ha bigmack,

I hear you!!
The one we had worked fine, it was just a basic little one......but it seems that it grew legs.....

Hi Merilyn,

Yes, the little bit of research I've done seems to suggest most of them are oil free now.
Which is where I was hoping to head!
I just don't want to waste money on a fancier one if the cheaper ones are sufficient for our needs.

Hi all, We need to purchase a new vacuum pump, what do you all recommend? My H.T. wants a good one, she looked in the Labtek catalogue and saw a Diaphragm vacuum pump for $865. They also have a Rocker 300 vacuum pump for $521. Does anyone know what the difference is between the two, she has no idea ...

hi all, I have been asked to purchase a " Photoelectric cell ". The only thing I can find on supplier websites is a " Photoelectric cell base & terminals " for $130.00 The teacher doesn't actually know what it is she wants.....a year 12 Physics student has asked to do a Photo...

I believe it was only migrated to an online version, not updated. An updated version is supposed to be ready this year..........yeah, well, we will see!!

I tested the Golden Rain experiment this morning too.....with brilliant results!

I just made up the Traffic Light experiment, to test out before the teacher does it on Friday with the students, and it worked brilliantly!!
We showed it to a couple of year 11 (now 12) students and they were very impressed!

In the DoE we are not labbies, but School Admin Officers, SAO but us working in science have been known as Labbies for years. We are all paid the same as the front office ladies. As I have retired I can not say the amount, but believe it is about $26.90 per hour. Labbie, it is actually $29.90 per h...

we have "light gates" that work with our data loggers from Scientrific....

Thanks Labbie,
you guys are definitely great at helping and cheering!!
especially for the inexperienced, like me!!

Thanks linotas!

Thank you Lyn!!!
I have no idea why so strong.....I just work here lol!
I am having a bad week......lord help me for the rest of it!!

Good morning all, I have another question..... I need to make up a 1M solution of Iron (III) Nitrate, I have a recipe for 0.1M 40.4g in 950ml water + 50ml of 2M nitric acid and 0.5M 202g in 900ml water + 100ml of 2M nitric acid my brain hurts this morning....I'm not sure how much nitric acid to put ...

Thanks for the replies everyone. The name of the prac is "Iron Thiocyanate Equilibrium", or that's what she has called it! It's to do with Yr 11 depth studies....one student is doing this. The order was for Iron (III) Nitrate, Potassium Thiocyanate, Tin Chloride, Silver Nitrate, Sodium Hyd...

Hi all,

I have a teacher wanting to do the above mentioned prac on Monday, but I don't have any Tin Chloride......is there anything else I could use?? I love how they give you plenty of notice! Not!!

Thanks in advance
