How to refill the injector with oil
(by the use of a tube connector: CI-3)


Here is the information to refill the IM-9A / IM-9B with oil.

The serial number of the IM-9A product; No.05075 and earlier or the IM-9B; No.05431 and earlier, used to include a Tube Connector (with Multi-use Valve): CI-3 as accessory. For refilling IM-9A/B with oil, currently Narishige recommends to use a three-way stopcock, however, you are able to refill them by using the CI-3 as well. If you would like to refill oil by using a three-way stopcock, please refer to this link.

* The same procedure, in principle, may apply to other models (IM-6, IM-5B, etc.)

* Commercially available oil is required to fill up the oil.


Step1

1. Remove the multi-use valve of CI-3 by turning it counterclockwise.

Turn the control knob clockwise to purge air completely from the microsyringe.

Step2

2. Insert the cleaning rod into the injection holder, being careful not to allow leaks of oil from the end of the injection holder, and secure it.

Step3

3. Fill a disposable plastic syringe with oil and insert the syringe into the hole in the multi-use valve to inject the oil into the microsyringe.

To inject the oil, while pressing the plastic syringe with moderate strength, turn the control knob counterclockwise.

When injecting the oil, air bubbles trapped in the microsyringe can impair the operability, and thus air bubbles should be removed.

To remove air bubbles trapped in the microsyringe, with the tip of the microsyringe pointing upward, turn the control knob clockwise to move air bubbles to the multi-use valve and discharge them into the disposable plastic syringe.

Step4

4. After the microsyringe is filled with oil, pull out the cleaning rod (inserted into the injection holder in the procedure 2).

Press the plastic syringe with moderate strength to fill the injection holder set with oil.

In this procedure, air bubbles trapped in the PTFE tube can impair the operability and thus, remove air bubbles.

Step5

5. To prevent the entry of air bubbles, with the hole in the multi-use valve filled with oil to overflowing, tighten up the multi-use valve firmly.
