Hi Lorrae - Thank you for that excellent suggestion, I'll see if I can find someone to help. Being in the central west of N.S.W it is not always easy to access suppliers, as you can appreciate. Once again, thanks. Cheers, Judy.

Thanks Marjan, just as I figured!!!! However when one is 250 miles from Sydney it is not always easy to access suppliers. However I will have the phone number of the "Freeze it" mob, just in case they have a local supplier (highly unlikely, but you never know!!) Thanks in advance. Judy

Dear All - I need to purchase some liquid nitrogen for a Physics prac. In the past I have managed to get a small amount in a thermos flask from the local Vet, just wondering, is this what others do? I find the stuff evaporates very quickly (maybe the lid was not on properly, and transporting in my c...

Dear Liz - Thank you for your help. I knew I had a copy of the recipe somewhere (not in the usual place!!!) and I was unable to find it! Many thanks. Cheers. Judy.

Dear All - I'm looking for a recipe for Schultz solution (Test for Cellulose) There is supposed to be one in the CSIS Training manual, but I am unable to find it. Any of you good people help? Looking forward to your reply. Cheers. Judy.

Thanks Kim, you are a gem. You've gotta love this site!!! Cheers. Judy.

Dear All - Have any others made artificial ore - this is a first for me! I have a recipe - Sand, Copper sulphate and marble chips embedded in Plaster. However I am not sure what Plaster - Plaster of Paris? Plasticine? Any one help?

Thanks Mother, that makes me feel a lot better and I look forward to further developments, if any! Good luck with the audit! Cheers. Judy.

Mother - was it you talking about mini MSDS's late last term? You were having a meeting with your OH & S rep about mid December and you implied that the use of the single page mini MSDS might be O.K. This is how we have been operating for some time and I would really like to know if we are doing...

Don't know about otheres, BUT I am really curious about the ROW!!!!!

Dear Rae - You can purchase the Nitrile gloves at Science Supply Australia, Livingstones, and of course Q Stores. They are approx. $15 per packet of 100 (although that varies!!) They come in different sizes, not lined, contain no Latex and have good chemical resisting properties as well as being a r...

Dear Ian, I see Robb has given you a recipe for this stain, mine is a little different: 0.1g of Phloroglucinol to 70% ethanol solution. Just a little tip that caught me out a few years ago - Prepare the solution several weeks before being used and then mix with Conc. HCl Mix 100ml Phloroglucinol sol...

Dear Robb - Thank you very much for your informative advice, I will stick with the Nitrile gloves, approximately $15 for a packet of 100 as opposed to approximately $12 for a packet of 12!!!! Yes, I did eventually find the Neoprene/latex gloves in the "Church Resources Education Catalogue!!&quo...

Dear Rae and Robb - Thanks to you both! The Q Stores book I am using is about 4 years old and the new book!!!!!! (Church Resources Education Catalogue) is fairly hopeless. So Rae, if you have the Catalogue number handy I would appreciate it! Robb, I was just following the Glove recommendations on th...

Dear Jazz - Use dilute NaOH (just a few drops) this should do the trick. Judy.

Dear All - Need some help locating suppliers of Butyl/Neoprene and/or Neoprene Gloves. A number of MSDS's recommend these particular gloves to be used with a number of organic compounds. We have the more commonly used Nitrile gloves. Have tried Q Stores, Livingstones, Southern Biological, Haines and...

Thanks heaps Nicole, it is a relief to learn that I haven't been doing things incorrectly all this time!!! I always try to supply the mini MSDS and /or the CHINA report with the understanding that access to the full MSDS is easily available online, if fact our RA's have a section which can be ticked...

Many thanks for your advice, Mother, Jazz and Helen. I did try the web address (and that was some address!!!) however I was interupted by one of the teachers and haven't got back to it! The Bio teacher involved is having second thoughts about the Trypsin anyway after consulting with collegues and ma...

Many thanks for your input Robyn and Sheryl, yes you are right the vials are autoclavable and therefore should be able to be passed through a flame without any problems. I also think it would be a good idea to keep some McCartney bottles on stand by! Once again, thanks for your advice, much apprecia...

Dear All - must be my day for problems!! (second request!!!) We have purchased some E-coli and Staphylococcus broth for culturing: however the broth arrived in plastic vials, so how does one go about flaming the neck of the vial with the idea of streaking prepared agar plates. What do others do, do ...
