ADAPTERS & SAMPLE RECEPTACLES
There are two main types of sample receptacles:
- Bottles & Other Open-top containers (in blue below)
- Closed containers such as pressure cylinders and piston-injectors (in orange below)
There are two main differences between each type:
- In principle, bottles and other open-top containers can’t hold any pressure. If pressure can’t be released and must therefore be contained, a closed container is thus required.
- Exposure to toxic fumes and/or vapor cannot be avoided with bottles & other open-top containers. To guarantee absolutely no exposure, a closed container is therefore required.
The exception to #2 above is our REVO-BOX: the sample is collected in a bottle and the cap is screwed back onto it in a totally closed environment. This eliminates any exposure for the operator or the environment.
|Bottle Support||The bottle sits on a spring-loaded support. The operator can easily lower the support to remove the bottle from under the valve.||The operator is exposed to toxic fumes / vapors of the sample which are released from the bottle.|
|Thread Adapter||The bottle is screwed under the valve. To remove the bottle, the operator has to unscrew the bottle and then screw the cap on it.||The operator is exposed to toxic fumes / vapors of the sample as soon as the bottle is unscrewed from the valve and until the cap is screwed back on it.|
|Needle Adapter||The needle is used to burst the septum of the bottle.||Due to the nature of the septum, the operator's exposure to toxic fumes / vapors of the sample is limited. This solution is not recommended for slurries, highly viscous products or application than can plug.|
|Safety Cabinet||The safety cabinet adds an extra layer of safety to a bottle support, a thread adapter or a needle adapter.||The safety cabinet reduces exposure, but the operator is exposed when the door is opened to get the bottle. The cabinet can be vented during and after sampling.|
|Revo-Box||Same as a safety cabinet, but the cap is screwed back on the bottle within the safety cabinet. Watch the demo.||The sample is collected in a bottle. The operator is NOT exposed to toxic fumes / vapors.|
|Piston-Injector||Syringe-type cylinder (no-flow-through) using a piston to push/pull liquid or gas||The sample is collected in proprietary cylinder. The operator is NOT exposed to toxic fumes / vapors. The sample can then be transferred into a bottle or other equipment at the lab, in a controlled environment (i.e. under the hood).|
|Container||Proprietary cylinder (no-flow-through)||The sample is collected in proprietary cylinder. The operator is NOT exposed to toxic fumes / vapors. The sample can then be transferred into a bottle or other equipment at the lab, in a controlled environment (i.e. under the hood).|
