Sealing rings for different foaming methods and liquids
- Bookmark
The available sealing rings (the figure to the left shows a selection) are required respectively for foaming using gas flow or a stirrer or for manual foaming-up. You can also prepare your measuring instrument for analyses of different types of liquid samples with the choice of the sealing material.
The following sets of sealing rings are available1:
| Name | Pieces per set | Type of foaming | Used for columns/filters | Material | Suitable for |
| FI4511 | 5 | stirring or manually | CY4501/03 CY4571/72 | silicone | aqueous solutions |
| FI45122 | 5 | manually | CY4502/04 | silicone | aqueous solutions |
| FI4513 | 5 | stirring or manually | CY4501/03 CY4571/72 | EPDM | aqueous liquids (also acid and alkaline); polar organic liquids (alcohols, esters, ketones, amides, nitroalkanes); silicone oil |
| FI4514 | 5 | manually | CY4502/04 | EPDM | aqueous liquids (also acid and alkaline); polar organic liquids (alcohols, esters, ketones, amides, nitroalkanes); silicone oil |
| FI45313 | 10 | sparging | CY4501/03 CY4571/72 | silicone | aqueous solutions |
| FI4533 | 10 | sparging | CY4501/03 CY4571/72 | Viton | mineral oil, silicon oil |
| FI4550 | 5 | sparging | CY4501/03 CY4571/72 with FL4550 (paper filter holder) |
