Are these the bags they use when you donate blood ? If so you could try asking the blood transfusion group when they are in your local area ? Just suggest a small donation in return for a few bags, make sure you get empty bags  {-)

The gas turbine powered model aircraft use them as fuel tanks.  Try Als Models or one of the engine manufactures such as Wren.

Go to your local chemist and ask nicely....that's where mine came from.

Sorry boater12 your idea is good but won't work - my wife before she was a GP worked about 10 years for the National blood Transfusion service
(that was about 17 yrs ago) and the bags then were some ridiculous price _ if I remember rightly they were about 23 each then!!!
If anybody didn't give a full donation they had to be ditched and the bag was wasted.   so your idea of a cash donation will not work.

I have seen the air bags from blood monitors used on a sub , often you can get these for 9.99 form main chemists, ie Lloyds.  Also I have seen used the bags from the rehydration drinks.

i use armbands for a similar use,i use a peristaltic pump as per norbert bruggens set up  in my sub - but i  did not want to make my own 'gummi sack' as a reservoir so looked at alternatives - look at the different sizes of kids arms bands, they are often made up of several different size chambers each with its own blow up valve... i found a kids armband had a chamber the right size for my needs so use that, its flexible, very durable and perfect for the task in my sub....

The larger Capri-sun bags (the ones with the screw top) can be adapted for use as ballast bags. They won't suit every model, but they're a very inexpensive solution, plus you get to enjoy the contents too.

Surely used Colostomy bags would be better as they will already contain ballast  :-)) :-))

HOw about the bags you get inside boxes of wine, with the additional benefit of drinking the contents

Thanks guys some good idea,s there.
I think ill ditch the plasma bag idea {too costly} the ship is
2 mtrs x 24 cm x 17 cm so at a tenner a time !!!!!!!!
ill have a look at the home brew/armband idea.
The thinking was that by using water ballast, i do not have to lug
a barrow full of junk to and from the pool.
again thanks.

You can use blood pressure cuffs, either buy replacements in different sizes or a whole blood pressure machine with a airpump is cheap on eBay.

I have a neighour that's a male nurse and works in the local hospital. On one of his many visits to borrow something he noticed that I was playing around with lead ballast in a 1:72 scale battleship. Instead of using lead he suggested to use Saline/Glucose drip bags as they come in sizes from 500ml to 2 Litres and can be filled with water. Should any Oz members need some bags, I have a great collection and can get many more. The bags consist of used bags that were to be thrown out and Out-of-Date bags (expired)...Apparently, another modeller told me the bags can hold fuel for IC boats as well.

I think it will be far easier to get Glucose/Saline bags than Plasma one's for health reasons.

See those yellow skips at hospitals .. they are probably full of plasma bags .. try A&E ... there's always people in there walking around with them held up in the air ....

Now I have a vision of sub modelers mugging patients and routing around in hospital skips ....
