Swan-neck flasks
Hi all,
Im in the Southern Highlands, NSW and was wondering if anyone knows where to purchase swan-neck flasks? These are to be used for the Modelling Pasteur's experiment year 12 Biology.
Thank you so much for your help Tammy

Re: Swan-neck flasks
we used coiled clear plastic bunsen tubing, attached to a glass rod, inserted thru a rubber stopper with a hole. (cheap and easy!)
If this doesn;t make sense, i can photograph it...

Re: Swan-neck flasks
Hi Tammie,
I'm at Oxley!!
We have made our own in the past. It's not hard and the kids can do it if they are careful.
Not much help I know but maybe one of your teachers has some experience bending glass and could help.

Re: Swan-neck flasks
To sterliaize just use milton, good enough for babies etc, good enough for us. Cold water.

Re: Swan-neck flasks
They have to boil the broth for 15mins with the attached tubing, any nasties will be killed. No need to sterilise.

Re: Swan-neck flasks
Ours are similar - easy to make and easy to replace if needed.
Re: Swan-neck flasks
I use the plastic ones from a home brew shop. You can buy them with bungs that fit. I sterilize them using NaOH sterilizer from the shop as well. It is essentially 4M NaOH, which is then used at 5mL/L. Beats the hell out of trying to bend glass, especially with short notice.
Cheers, K
Re: Swan-neck flasks
Hi, it's not all that difficult to bend glass tubing and fit it through rubber stoppers.
Just takes a little patience. Some artistic variation does occur between the swan necks but this does add to its individuality.
Keep a set and re-use each year.

Re: Swan-neck flasks
Yes I have a set of artistically creative 's' bends. Every now and then a couple get broken so I have to be creative again. No problem.
