Measured vapor uptake isotherms and kinetics are used to characterize, test and evaluate materials in precisely defined environmental conditions.
An ultra-sensitive microbalance measures changes in sample mass as a function of humidity and temperature. Humidity is determined by relative mixing of wet and dry gas streams, and is measured and regulated at the sample position. These factors combine to offer unrivalled performance and total baseline stability.
Features:
- Market-leading weight stability, temperature and humidity control
- Unrivalled measurement precision, accuracy and resolution
- Operation with water and organic vapors
- Built-in user conformance tests for weight, temperature and humidity verification
- High security 21 CFR Part 11 compliant software option with 3 user privilege levels
- Advanced analysis features including diffusion coefficients, permeation rates and more

Built on the same proven engineering as the flagship IGAsorp systems, it delivers the accuracy required for routine moisture-sorption work while keeping operation simple and data quality consistently high. By focusing on the performance factors that matter most – stability, reliability, and ease of use, the Core offers a practical, high-value route into dynamic vapor sorption.
To achieve this, the system combines highly stable temperature regulation with feedback-controlled humidity generation to maintain tightly defined sample conditions. An ultra-sensitive microbalance captures mass changes with high resolution across the full humidity and temperature range, while HIsorp software manages method setup, data capture, and analysis in a unified environment. Together, these components create a robust, reliable platform for generating trustworthy sorption data with minimal effort.
Features: - Unrivalled temperature stability from 15-40 °C;C, powered by the compact, high-performance iSSB thermostat
- Fast response RH sensor and high-precision flow control for accurate humidity regulation
- Temperature and humidity measured directly at the sample for true environmental accuracy
- An ultra-sensitive, independently thermostatted microbalance for exceptional long-term stability
- HIsorp software streamlines workflows with guided methods, automatic reporting, and integrated analysis
- Unique IGA method for endpoint determination delivers high measurement accuracy and shorter experiment durations
- Built-in conformance tests for weight, temperature, and humidity verification
- Optional 21 CFR Part 11 compliant mode with three user privilege levels for secure, regulated operations

The Next Generation Vapour Sorption Module unlocks a wider range of DVS conditions than ever before, enabling fast, stable and highly accurate studies across water and organic vapors. With robust engineering that maintains exceptional measurement reliability even under demanding environments, IGAsorp Ultra is the definitive choice for laboratories that value both innovation and dependability.
The IGAsorp Ultra integrates dual vapour generators for flexible multi-solvent studies with direct concentration measurements for traceable vapour control. Highly stable temperature regulation is delivered through the isothermal design of the sorption module, while a highly sensitive microbalance captures mass changes with high resolution across the full humidity/vapor pressure and temperature range. Effortless operation and automation run throughout the system and HIsorp software, making DVS measurements quick to setup, easy to control and consistently reliable from the very first data point.
Features:- Dual vapor generators -
Two independent vapor generators provide flexibility when working with water and organic vapors. While one vapor is in use, a second can be primed and ready for use in measurements. - Rapid, efficient solvent changeovers -
Highly efficient, automatic purging following vapor changes minimise unwanted carryover between measurements. - Direct vapor concentration measurement -
Integrated sensors provide real-time monitoring of relative humidity and organic vapor concentrations. A unique absolute pressure sensor ensures high accuracy for reported partial pressure readings. - Easy-refill reservoirs -
Each vapor generator is supplied and kept at a constant fill level by an externally mounted 250 mL reservoir. Reservoirs can be refilled during measurements without interrupting the experiment. - Effortless sample loading -
Sample loading is fast and simple, with clear access, easy single-finger placement, and an automated shield that protects the chamber and retracts smoothly for trouble-free loading. - Exceptional temperature control and programmability -
IGAsorp Ultra delivers precise, programmable temperature control from 5–85 °C with tightly regulated circulation and multi-sensor feedback that maintains ±0.005 °C stability over 24 hours. Alternative thermostat options are available. - High stability microbalance -
IGAsorp Ultra's independent balance thermostat ensures long-term baseline stability, enabling confident measurement of sub-microgram sorption events.
