SPS DYNAMIC VAPOR SORPTION SYSTEM – PROUMID
Model: SPS
Manufacturer: ProUmid
Origin: Germany
Key Features
High Multi-Sample Analysis Efficiency
The SPS system can analyze up to 23 samples simultaneously in a single run. Samples are arranged in a circular carousel, and an automated system places each sample on the balance for weighing.
Advanced Balance Technology
- The system features micro and ultra-micro balances with top-loading technology, allowing samples to be directly placed on the balance pan without the need for tweezers.
- Long-term balance stability is ensured through internal referencing, eliminating drift during measurements lasting over 24 hours.
Wide Load Range and High Resolution
- The wide load range from 3 mg to 220 g ensures precise and reproducible results across various sample sizes.
- Balance resolution ranges from 0.1 µg to 10 µg, providing maximum accuracy for both small and large samples.
Broad Temperature and Humidity Range
The SPS system operates under temperatures from 5°C to 60°C and relative humidity levels from 0% to 98% RH, enabling the study of material behavior in extreme environmental conditions.
Easy Calibration and Validation
- The system offers automated balance calibration using internal reference weights.
- Humidity validation is performed using salt standards or certified reference materials.
Intelligent Control Software
- User-friendly software allows easy configuration of sorption/desorption cycles.
- Continuous real-time data updates are displayed in table and graphical formats for monitoring during experiments.
Easy-to-Clean Design
The sample tray can be removed for preparation outside the chamber, reducing contamination risks. Flat internal surfaces make cleaning the chamber simple in case of accidental spills.
Durability and Long-Term Support
The SPS system is built for long-term continuous operation. Accessories and software are compatible with older models, ensuring effortless upgrades without full system replacement.

Notes:
- * The full humidity range can only be achieved when the chamber temperature is slightly above room temperature.
- ** Reproducibility assumes installation in an environment suitable for micro or submicrobalances.
