Clean the flow-through cell
Ensure the flow-through transmission cell is clean before and after sample measurements with the Affirma Lubricant Analysis system. Use heptane or isooctane, a clean syringe, non-abrasive wipes, nitrile gloves, and safety glasses. Avoid chemical exposure and excessive pressure. Clean the cell with solvent and air after the last sample of the day.
Make sure the flow-through transmission cell is clean before and after taking sample measurements with the Affirma Lubricant Analysis system.
Materials required:
- Small volume of heptane or isooctane
- Clean 10 ml Luer-Lok syringe (latex and silicone-oil free)
- Clean, non-abrasive laboratory wipes (unscented and lotion-free; paper napkins work well)
- Powder-free nitrile gloves
- Safety glasses

Avoid chemical exposure. Isooctane and heptane are chemical irritants. When handling isooctane or heptane: • do not ingest
|
To clean the flow-through transmission cell
- If a sample syringe is connected to the cell inlet port, remove the syringe from the inlet port.
- Use a clean laboratory wipe to remove any excess oil from the adapter connected to the cell inlet port.

Splash hazard. Avoid applying excessive pressure to the flow-through cell (via the syringe). Sudden leaks can cause a skin and eyes splash hazard. |
- Fill a clean syringe with about 5 ml of heptane or isooctane.
- Screw the end of the syringe into the adapter on the cell inlet tubing and slowly inject all of the solvent through the inlet tubing, flow-cell, outlet tubing and into a waste receptacle.
After you finish measuring the last sample for the day, it is a good idea to clean the cell with solvent and then inject a syringe full of air through the cell to remove the excess solvent.
