What are the requirements for generic cuvettes for the NanoStar II? - WKB319090
ENVIRONMENT
- NanoStar II
- Wyatt 2-µL Quartz Cuvette (WNQC02)
- Wyatt 45-µL Quartz Cuvette (WNQC45-00)
- Wyatt 4-µL Disposable Cuvette (WNDMC*)
- Generic Quartz Cuvette (900342)
- Generic Plastic Cuvette (900341)
- Adapter for Generic Cuvettes (900343)
ANSWER
The NanoStar II supports both Wyatt and generic cuvettes, including quartz and plastic types. Wyatt cuvettes offer compatibility with DLS and SLS, while generic cuvettes are limited to DLS only. Temperature ranges vary, with Wyatt quartz cuvettes supporting up to 120°C and generic cuvettes limited to 70°C by firmware. Toluene compatibility is only available with Wyatt quartz cuvettes. Generic cuvettes must have outer dimensions of 12.5mm x 12.5mm and a sample fill level of 10mm from the bottom.
ADDITIONAL INFORMATION
What are the requirements for generic cuvettes for the NanoStar II?
In addition to the Wyatt 2-µL and 45-µL quartz cuvettes and Wyatt 4-µL disposable cuvettes, the NanoStar II can be used with generic quartz cuvettes and generic plastic cuvettes.
Below is a summary of cuvette options:
| Cuvette Material | Volume | Part Number | Toluene Compatible? | DLS only or DLS + SLS? | Temperature Range (°C) |
| Quartz | 2 µL | WNQC02 | Yes | DLS + SLS | -10 to 120 |
| Quartz | 45 µL | WNQC45-00 | Yes | DLS + SLS | -10 to 120 |
| Disposable 4 µL cuvettes (pack of 30 individually sealed cuvettes, includes 3 silicone caps) | 4 µL | WNDMC* | No | DLS only | -10 to 80 |
| Generic quartz cuvette (case including lens tissue and foam applicators) | variable | 900342 | No | DLS only | -10 to 70 ** |
| Generic plastic cuvette (pack of 100, includes 10 caps) | variable | 900341 | No | DLS only | -10 to 70 ** |
*A pack of 500 disposable 4 µL cuvettes is also available with part number WNDMC500 (Wyatt).
**If using generic cuvettes, check the information from the cuvette vendor. The NanoStar II firmware limits operation with a generic cuvette to -10 to 70 C, but this does not guarantee the generic cuvette is compatible with this temperature range--always check with the manufacturer for their temperature limits.
The adapter for generic cuvettes (quartz or plastic) is part number 900343.
The outer cuvette dimensions for generic off-the-shelf cuvettes must be 12.5mm x 12.5mm (see diagram below). The recommended sample fill level is 10mm from the bottom of the cuvette. (The beam location is ~5mm from the bottom of the cuvette.)
