Tubing for Bunsen Burners

Post by gwen »

Hi Everyone,

Does anyone know the specifications for tubing for LPG bunsen burners?

Q Stores couldn't help.

Cheers,
Gwen

Hi Gwen
For safety reasons you need to use clear plastic tubing for the bunsens as the rubber tubing perishes and splits very easily.Students find it very easy to put pin holes in the tubing which is dangerous when the gas is on.The lab tech.I replaced had a very nasty experience when the gas escaped through the tiny holes which she didn't see.Q Stores Item No for the tubing is: 998470.It tells you the tubing is for Bunsen Burners.
Hope this helps you
Take care

Yes I thought we were advised to use clear tubing for the reasons you mentioned but the last time I ordered clear tubing, Q Stores sent me the RUBBER tubing instead. When I checked the catalogue (mine is 2006) the tubing listed for bunsens was the rubber not the clear. The rubber is 8 mm internal diameter but the clear doesn't come in that size. Has anyone found a supplier for the correct size clear tubing?? Thanks.

Thanks all for replies.

We have been using clear plastic tubing for 23 years but the Q Stores catalogue threw me when 8mm clear tubing is not advertised. They say 8mm rubber is used for bunsen burners.

We'll continue to use clear tubing as it has been very satisfactory. However I have seen rubber tubing on bunsens around some labs in this area so wasn't sure if the plastic was OK.

Thanks again,
Gwen

Same here. Q stores sent us the brown 8mm tubing when clear was requested and yes we've had trouble with the rubber perishing very quickly as the gas inside seems to dry/chill the rubber and make it brittle.

We use the vacuum rubber tubing, with the 3mm thick walls. The rubber doesn't perish very quickly, and it's much more vandal-proof than the plastic tubing. Mind you, surprising though it may seem, that type of vandalism just doesn't seem to occur in this all-girls school anywhere near as much as other co-ed schools I've worked at in the past. Maybe we're just do more interesting stuff in class, so they're never bored? Yes, that must be it!

Cheers, K 8-)
