PRODUCT DESCRIPTION

The GatheRex™ Cell Harvest Pump is a liquid handling device designed to work with closed-system cell culture devices. The GatheRex connects to closed system devices and uses a low-pressure forced air mechanism to remove media, and concentrate cells and minimize storage and/or downstream processing. An internal air pump pressurizes the system by pumping air through the sterile vent filter on the cell culture device. When pressurized, excess media, or a cell fraction, is forced out of the device through the tubing assembly and then into a collection receptacle.

• Model 80000E is designated by white ID tags on the tubing pinch clamps. This version is compatible with small-diameter tubing (0.160” OD; blood transfer bag style) for both media removal and cell recovery.
• Model 80000Z is designated by black ID tags on the tubing pinch clamps. This version is compatible with large-diameter tubing (0.375” OD) for media removal and small-diameter tubing (0.160” OD blood transfer bag style) for cell recovery.

EXAMPLE OF USE – Media Reduction and Cell Harvesting from a closed system G-Rex device

1. Ensure the pinch clamps for the selected fluid pathways are open to the media and cell collection bags.
2. Press the RED Right Arrow (à) to begin Media Removal (Reduction) through the red striped tubing or the large diameter CFlex tubing. The headspace of a closed system G-Rex device will be pressurized moving waste media to the collection bag. This will continue until the cell culture media level reaches the end of the internal media reduction line (~1 cm from the bottom). Once media removal from the G-Rex device has been achieved, media flow will stop automatically via a sensor located within the red tubing clamp.
3. Swirl the remaining volume in the G-Rex device to resuspend the cells existing on the gas-permeable membrane. Tilt the device to allow the fluid to collect/pool where the internal harvest line touches the base/side of the vessel.
4. With G-Rex still tilted, press the BLUE Right Arrow ( – >) to begin Cell Recovery (Harvest). The G-Rex will be pressurized moving the cell population and all remaining fluid into a Cell Harvest Bag. Media flow will stop automatically via a sensor located within the blue tubing clamp.
5. Optional Steps to harvest any potential remaining cells in the GRex cell culture device by way of a rinse procedure:
   • Partially refill the G-Rex with Media from the Red Removal Circuit by pressing the RED Left Arrow (ß) button. This releases the clamp for the red-striped removal conduit, allowing fluid to be gravity-fed or forced back into the G-Rex by squeezing the waste media bag manually or with a pressure sleeve.
   • When the desired volume of media has been moved back into the G-Rex, press the RED STOP (X) button to re-clamp the red-striped removal conduit.
   • Swirl the fluid within the G-Rex to capture and resuspend any remaining cells.
   • With the device tilted towards the internal harvest line, press the BLUE Right Arrow ( – >) button for cell harvest. Media flow will stop automatically via a sensor located within the blue tubing clamp.
6. Clamp the reduction line and the harvest line to seal the waste media collection bag and cell collection bag.
   • Alternatively, simply seal the collection bags with a sterile tube sealer.
7. Press the release clamps on the GatheRex Pump and remove the tubing.
8. Seal the collection bags with a sterile tube sealer.
9. Discard the G-Rex vessel and the waste culture media.
10. See examples of setup with G-Rex at the end of this document.

MAINTENANCE AND SERVICE

• Maintenance – There are no maintenance items on the GatheRex other than periodically wiping down the exterior of the device with 70/30 IPA.
  • Use care not to over-saturate or immerse the device.
  • If the power cord becomes damaged contact Wilson Wolf for a replacement.
  • All repairs and services must be performed by Wilson Wolf.
• Inspection – Pressure output should be verified before each use using an external calibrated pressure gauge (see air pressure verification details below).
• Air Pressure (verification) – Note that the internal pressure regulator cannot be adjusted (i.e., output pressure can only be verified). To measure pressure output, connect a calibrated pressure gauge to the compressed air outlet port and tubing. An appropriately sized fluid-filled tube must also be placed into the pinch clamp/sensor to allow the pump to run for more than 6 seconds once initiated using the – > key.
• Fuse Replacement – Unplug the cord from the wall outlet. Remove the Cord from the Power Module on the back of GatheRex. Pry open the top of the access door of the Power Module with a flat screwdriver. Use a flat screwdriver to pry the side of the Fuse Carrier for removal. Inspect and replace fuse (see page 1 for fuse type). Re-insert the Fuse Module into GatheRex with the appropriate voltage positioned at the top (i.e., 115V or 230V). Close the Power Module door and verify the desired voltage is shown through a window in the Power Module door. Re-install the Power Cord and plug it into a wall outlet.

TROUBLESHOOTING

• If Flashing Red Power LED – If the system is unable to build pressure (i.e., system leak) the GatheRex will run for approximately 33 seconds and then stop the air pump. The red power LED will flash red. To reset, turn the device off and then back on again. Fix the system leak before restarting the cycle.
• If the GatheRex Air Pump will not run longer than 6 seconds – Verify that the tubing is fully seated in the pinch clamp and that fluid fills the tubing within 6 seconds. If air is present in tubing the pump will stop.
• If Green Power LED will not light – Confirm outlet has power. Verify that the power cable is fully seated in the outlet and back of the device. Confirm GatheRex power switch is turned ON. Inspect and/or replace the Fuse per Maintenance and Service instructions.
