Surface tension
Administrative data
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-10-23
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:

Data source
Reference
- Reference Type:
- study report
- Title:
- Unnamed
- Year:
- 2 009
Materials and methods
- Principles of method if other than guideline:
- Pendant drop
A syringe was filled with approximately 10 ml of the solution and was attached to the instrument. The solution formed a drop on the tip of the needle.
This drop was examined optically by the software. The surface tension was calculated by the shape of the drop.
The pendant drop method used has been compared to the ring method OECD 115 and gave good correlation - GLP compliance:
- no
- Type of method:
- other: pendant drop, Perstorp A1577
