Clean the flow-through cell
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.
