What are the common causes of sample needles not piercing PTFE/silicone septa effectively? - WKB229797
Article number: 229797
ENVIRONMENT
- Sample needle
- PTFE/silicone septa
ANSWER
- Dull needle
- Misaligned needle
ADDITIONAL INFORMATION
As a needle wears, it can become very dull and may not pierce septa as effectively. Needle replacement is necessary in this case.
If a needle is not properly aligned, you may encounter issues with septa piercing. Misalignment can also lead to septa dislodging during injections, because the septa are pushed rather than pierced.
