jumbo syringe (100-200 mL)?

[ForestryUBC]

Is anyone aware of a 100 or 200 mL plastic syringe with a rubber plunger and Luer lock needle connection? I am making up dilutions of gas standards in 1-liter gas bags and a larger volume of gas injected would lead to more accurate dilutions (especially at lower concentrations), but also reduces the amount of injections needed through the tiny bag septa.

We have discovered that plastic syringes (BD brand) have worked well so far but the largest volume seems to be 60 mL. I have seen 100 mL glass gas-tight syringes but they are kind of pricey, which is not good around butterfingered students. I have also seen 500 mL plastic gas syringes, but that seems to be overkill.

Thanks, all.

Hope you don't have something that sticks too much to the rubber. BTW, I do this myself for some things.

Look for 'wound irrigation - or blister syringes' (100, 120, 200 ml) also from BD or others.
Some comes with an adapter to get luer-connector

Also look for catheter syringes, they can come in some pretty big sizes, upto 200ml in plastic (and hopefully un-used). The tip might not be a luer fitting though, but we have used these in the past to sample large volumes of gas. In the end we opted for a jumbo gas tight syringe (500 ml) from SGE:

It is a beast of a syringe, and saves you from going to the gym when sampling through a needle for a large volume of gas. But it has really improved our data for N2O isotopic analysis, by being really gas tight and preventing contamination from atmospheric N2O. Pretty pricey , around 450-500 UK pounds. So keep well hidden from students.

Nick576 has the syringe you're looking for. We've nicknamed our one liter version the 'Austin Powers'. Smiles and silly jokes all around when we break that thing out.

tdgcuser, that's great!. I can certainly see how the syringe can help with getting one's mojo back!
