Distributor & Service Provider In India
The tip-scanning AFM for heavy and large samples up to 300 mm
- Standard AFM system
- 300 mm x 300 mm sample stage
- Ideal for samples up to 45 kg
Nanosurf is the market leader for custom developed systems for large and heavy samples. Over the past years our team has built a substantial knowledge base developing these custom stages for various customers.
Utilizing this vast body of knowledge, we have now developed a standard product for large samples up to 300 mm or heavy samples up to 45 kg. The Alphacen 300 reduces the price and the delivery time compared to a custom system.
