There is a point to this,do you know what it is?(7 inches long)
-
Aluminium canisters with screw-top lids? >:D
Possibly designed to have a string tied around in the groove near the neck.
One has a hole worn in the bottom that I can see. Not very practical!
I've got an old glasses case in aluminium they remind me of, just a little.....
-
:pb: should probably of said what do they contain? ::),not very exciting but interesting if you're 'sad' like me :pb: :pb:
-
Test tubes?
John
-
Close but no,is no-one else going to take the plunge??
-
Something made of British or Irish glass I'd guess! Too wide for thermometers? Maybe something military? Can we have some clues?
-
Is 'take the plunge' a clue?
-
Thingies for testing the specific gravity of a liquid, like we use for wine-making, but I've forgotten what they are called! :pb:
-
Oh dear... and here I thought they had something to do with toilet or pool issues. :-[ Obviously no connection with glass there.
-
Slightly off-topic here but when doing a wee Google search for these items I found these interesting items
http://www.winebusiness.com/wbm/?go=getArticle&dataId=88152
Could be quite collectable I reckon.
-
Was going to make a few more bad puns like 'it might get under your skin' etc... but thought I'd post the pic',don't get to excited :pb: :wsh:
-
A Chance syringe, now that would get under your skin! :24:
-
Oh, I wasn't expecting that...
Keith, how lovely that you've got the syringes with their original containers. An interesting find, to say the least.
-
Somebody might like pictures for his next book!!

It's a good while since glass syringes have been used!
I can remember my Dad sterilising them when I was a child, but they were out of general use by the time I started working in labs in '75.
The aluminium canisters were essential to the sterilising process - the syringes were placed inside them with the screw-tops fitted only loosely, so the steam would penetrate inside them inside the autoclave.
(a sort of pressure cooker). When it was safe to open the autoclave, the tops were tightened, keeping the syringe sterile inside.
-
Both needles were attached so,carefully, I removed them and they are inside the tubes.The needles have very thin wires inside,was this to stop them from getting blocked or to clean them?
-
It may depend on the guage of the wire and the needle and on the size of the syringe.
If a syringe is being used for delivering a very tiny amount of fluid - say anything between 1-25 microlitres, the wire may have been essential for accurate delivery - it would overcome miniscal sorts of problems where fluid sticks to the sides. The wire would act as a much finer plunger.
Or it may be to prevent blockage of the needle.
Injection of lumps of things into people is highly dangerous - they cause embolisms.
But syringes (with needles) are used a lot in lab work as well as for injections.
-
Thanks Sue,the wire is very fine,got to be to fit inside a needle,I've a micrometer somewhere I'll see if I can find it ;D
-
Having had another look at the size of the syringe, I reckon the wire is simply to keep the needle unblocked. It's not one for delivering minute quantities, accurate to the last µl!
If it's being used as an extra internal plunger for the needle, it would be attached to the base of the glass plunger.
I can't make out the full volume the syringe holds, but it doesn't look too small. It does look more medical than lab ware.
-
Not attached to the plunger so just an 'un-blocker' as you say ;D
-
How much does the syringe hold?
Is it marked in decimal units or SI units or what?
-
10ml,with other marks saying D20 centigrade and a capital Z,presume this is something to do with cleaning the syringe.The plunger slides so well in the outer case you wouldn't believe it was around 60 years old.

ZZZZZZZZZZZZZZZZZZZ :thud:

ZZZZZZZZZZZZZZZZZZZ Thud
:24: :24: cheeky! ...made me laugh though! ;)
-
My brothers response when I told him about them,a glaze came over his face and for some reason he appeared not to be interested,why is that? ::) :thud: ;D ;D

I'm absolutely fascinated by the uses of glass in science.
But I'm a scientist.
We wouldn't HAVE science without glass - two of my greatest loves, intertwining. :smg:
