N/A

• The function of the cap is to keep the septum in place.
• The type of cap to be used depends on the bottle used for sampling.
• Each of our bottles is specifically fitted with a matching cap and septum, so that spillage or leakage can be avoided.
• As a general rule it is advised to use Dopak containers, caps and septa specifically for use with a Dopak sampling system.
• When samples are stored for future reference a double cap can be used for complete sealing after the sample has been taken.
• An additional septum can then be used between the under and extra overcap.
• Note that under-caps are different from standard caps; therefore over-caps cannot be used with standard caps.
• Under- and over-caps are supplied as a set.
