Description
IPDS II / 2T X-Ray Diffraction System
The IPDS II / 2T by STOE is a versatile X-ray diffraction system designed for structural analysis of both small molecules and proteins. Engineered for high precision and reliability, it delivers excellent performance across a wide range of crystallographic applications.
Key Features
- Single instrument for small molecules and protein crystallography
- High dynamic range (> 1:10⁵) for accurate intensity measurement
- Extremely low background (no dark current) for superior data quality
- Ideal for weak scatterers and sensitive samples
- Flexible configuration with optional dual X-ray sources
Advantages
- Accurate detection of both weak and strong reflections in a single measurement
- Extended data collection range up to 137° in 2θ (IPDS 2T)
- Full accessibility for sample environment customization (temperature, pressure, etc.)
- Long operational lifetime with low maintenance and cost of ownership
- Suitable for electron density studies and powder diffraction
System Capabilities
- Supports sealed tube and microfocus X-ray sources (Ag, Mo, Cu)
- Advanced goniometer with multi-axis rotation for expanded data coverage
- IPDS 2T allows rotation around the 2θ axis up to 60° for enhanced reciprocal space mapping
