Cannula Stoppers

Cannulae can be used with stoppers during manual sampling to ensure the sample is always taken from the same depth.

Stoppers are attached to the cannulae and sit in a hole in the vessel cover. If these are to be used then it is important to get the stopper and cannula to match the vessel cover type or manufacturer.

Top Tips

Sampling Position

The USP defines the sampling position as:

''A zone half way between the top of the media and top of the paddle or basket, not less than 1cm from the vessel wall.''

It should be noted that the sampling position is different for 500ml and 900ml tests.
