Containers and Holding Times


Many analyses require specific bottles and/or preservatives.  Please review the container documentation, and contact us if you have questions or need additional bottles.

In addition, many analytical methods require that samples be refrigerated from the time of collection until analysis, usually at less than 6°C.  Carefully review the sampling guidelines to determine any refrigeration requirements.
