| I just purchased one of your stainless filter holders and after only a few uses it is starting to rust. Is the unit defective? | Rusting of stainless steel holders can usually be attributed to high iron content in the water. Iron deposits create rust "stains" that can be removed with non abrasive cleaners or sometimes fine steel wool. All stainless steel can rust over time. It should be washed with DI water and dried thoroughly immediately after each use. |

| 1 | 顶盖及软管转接头 |
| 3 | 锁定环垫片，PTFE |
| 4 | O形环，PTFE |
| 5 | 滤膜支撑网，不锈钢，47 mm |
| 8 | 8号塞，9.5 mm (3/8 in.) 孔，硅胶 |
这些换膜过滤器特别适合于对液体成批进行超洁净或灭菌。量筒容纳100 mL（或340 mL）液体，外部提供的气体压力使这些液体通过由换膜过滤器底座支撑的合适的滤膜，而达到过滤目的。
特点及优点
- 换膜过滤器有一个储液瓶，可以容纳100 mL（或340 mL）的液体进行批量过滤
- 可装膜后高温高压灭菌用于无菌过滤
