Re: Maintenance Schedule
I agree Ian, feeling very lazy here. Love your philosophy Julie :thumbup: One thing I like to do on a regular basis is make sure when all "kits" come back in that they are checked and put back into order so that they are right ready to go when needed next time. By this I mean light boxes, ...

Re: Junket!!
Southern Biological also supply junket (code: MC23.85) 10gms for just under $10. Not sure if it appears in their current catalogue as it is a fairly new addition.

Re: rising and sinking sultanas
We have a very old one "dancing mothballs" which uses baking soda and vinegar. Not sure if its suitable any more, may be alright as a demo? (Naphthalene ok for years 11 and 12)

Re: data logger purchase
Hi there, We also have a Data Harvest data logger and are very happy with it. They're very user friendly and the back up from Serrata has been very good. (I should qualify that with the fact that we are only 15 minutes drive from them however.) We had a problem with the battery not long after we fir...

Re: incubators
Hi there, We have a litlle hot water cylinder in a cupboard under one of my prep. room sinks which sits at about 25 degrees. This does the job nicely, more than enough growth for the students and from a safety perspective you aren't encouraging human pathogens. They will still grow but you aren't se...

Just in case you haven't got recipe for the methylene blue stain. Stock Solution = 1.5g methylene blue in 100ml 95% ethanol. Dilute stock 1:10 with...

Re: Brain disection- help please
We use ethanol or methylated spirits. Works pretty well. Just soak for a couple of hours prior to use or overnight if needed first thing.

Re: Dry Ice
I get mine from Fiegerts also Robyn. If you are going to pick up give them a call first though as they close early sometimes I think. Also you could try Westside Wholesalers at Bella Vista. Phone 96590699. Not sure if they are even there any more and it was slabs of dry ice not the pellets. You paid...

Re: 10% HCl
Sorry Liz, I think by your reply you took me the wrong way. If hes away its a bit hard, teachers are not always clear with their requests are they. It wastes alot of our precious time trying to track them down and we're not mind readers.
Good luck

Re: 10% HCl
Would have done the same as you Barbara - a very handy little formular that one. Can I just suggest Liz that you go back to who ever asked you for this and check that they don't just want a straight 10% solution ie the old 10mls in 100mls etc. only because it makes quite a difference to the conc. th...

Re: Onion root
I've tried this a couple of times as well and only had limited success. Its very time consuming and I'm sure all in the way you hold your tongue at various points, there is a method in the book The Laboratory (available from Southern Biological- a must if you don't already own one) look under aceto-...

Re: junket
Southern Biological also now have Junket powder. Apparently two enterprising ladies who used to work for the "junket tablet" company have started their own little business supplying this.
