This is typically used for amidites on an oligo synthesizer but it can be used for other applications where a bottle of these cap sizes needs to have the ability to attach tubes and seal very well. Please specify the number of tubes that need to be attached, the size of each tube and if the tube is for pressure / vent or to flow liquid out of the bottle. This assembly does not include any tubing but ther are 2 each 1/4-28 ports for attaching tubes and one each pull through port for attaching a 1/16 OD tube. More tube connection ports can be added if needed.
