Tubing is only required if the user intends to perform flow chemistry experiments with the syringe pump system. Here the tubing instructions on how to connect the tubing to two syringe pump systems can be found. These instructions assume that the servo-motor mechanism will be used with the syringe pump system. The parts that are used for the connectors of the tubing are listed below.
A tubing tutorial filmed by the Croatt Research Group is available on youtube as well: Tubing Tutorial
Parts for Tubing Connectors:
Tubing (Nylon or PFA) 1/16” OD (0.02 or 0.04” ID)
PEEK Nut 1/16” [LT-115X]
Super Flangeless Ferrule System (includes steel compression ring and ferrule) [P-250X]
PEEK Union [P-702]
Take the steel compression ring and ferrule and with the flat side of the ring facing down place the ferrule on the top side of the ring.
2. Insert these parts with the flat end of the ring going first onto the narrow side of the PEEK nut. This assembly should be loose so be sure to hold onto it.
3. Run the tubing through the PEEK nut and then through the ferrule-ring assembly.
With the tubing sitting flat at the end of the ferrule-ring assembly, hand tighten the PEEK Union part onto the PEEK nut just until it cannot be screwed anymore with normal force. The union can be unscrewed after this.
*Two ends of tubing must have this type of assembly in order to connect the system together. Repeat these steps for the other end of the tubing, ensuring beforehand that the proper length of tubing is cut.
Parts for Connecting to the Syringe
1-4-28 Female to Female Luer [P-678]
1/4-28 PEEK Male Luer Adapter [P-655]
PEEK Y-Assembly [P-512]
Connect the red PEEK female to female luer by sliding it onto the smaller of the two openings of the stopcock valve. Ensure that the connection is not loose. If the servo-motor refill mechanism is not being used, then simply twist the same red PEEK onto the tip of the syringe. This is the dispensing end of the syringe pump.
2. With the other end of the tubing connector, tighten the nut onto one side of the PEEK Y-assembly. Another option that can be used here is a PEEK T-assembly.
3. For the refill side, take the red and black male luer adapter and hand tighten it onto the remaining opening of the stopcock valve using the black handle.
4. The other end of the tubing will use the same PEEK nut, but will have a blue plastic ferrule only instead of a ring and a ferrule. Steps 3 and 4 of the Tubing Connector assembly can be used to make the connection. This end of the tubing will be in direct contact with the reservoir for the refill mechanism.
