The Injectorr™ method eliminates the syringe in GC injections.

Sample flows directly from the needle to the sample loop. Contamination is efficiently purged from the loop with minimal use of sample.

 

Automated gas sampling with large flasks or bags is easy with the X10 Bandolero.

With a flask sampling belt adapter, a crate full of flasks can be sampled. No valves are involved: there is a straight path from the needle to the flask. Flasks and gas bags can be filled in the field and can be sampled to a GC in the lab. Incubation experiments in the lab can be connected directly to the GC or other instrument through a Bandolero™.

Incomplete vial evacuation is a problem in most labs.

If you think your Exetainers™ are evacuated, then you better test some of Your tubes: hold an "evacuated" vial upside down underwater and remove the cap. If it were evacuated it would fill completely with water. The bubble shows you how much air was in the "evacuated" vial. The photo below shows how much air was in these evacuated vials. The 4 vials in the middle were "pre-evacuated" vials purchased directly from Labco! "Lab B" results were from evacuating through a needle. The  Exevacuatorr Chamber solves this problem and gives results like "Lab A" on the left.

small bubble: good            Large Bubble: Bad

 

 Air will leak into the evacuated vial as you pull the needle out.

GRACEnet Protocols have not yet addressed the issue of incomplete vial evacuation. Reduce the contamination in your vials to insignificant levels.

Old style manifold: Obsolete!

Causes leaks in vial septum and is awkward to use. Swagelock fittings are good for some things but only if you follow the correct procedures for assembly. Conventional valves are prone to vacuum leaks.
