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.
| Adapter | Description | Exposure Level |
|---|---|---|
| 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). |
