AMI is pleased to introduce the next-generation STA (Simultaneous Thermal Analyzer), a state-of-the-art instrument for advanced thermal analysis.
Incorporating a 0.1-microgram balance resolution, sophisticated control algorithms, and an innovative hang-down design, the STA offers exceptional precision and reliability in a cost-effective, high-performance system.

The STA Series enables simultaneous Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) or Differential Thermal Analysis (DTA) on a single sample within a single test cycle. Built for precision and reliability, the STA delivers comprehensive thermal profiles without the need for running multiple experiments, ultimately saving you both time and valuable sample material.

Engineered for quality control, routine testing, academic research, and industrial R&D, the STA Series combines robust construction with user-friendly software for a cost-effective solution in high-precision thermal analysis.

The STA is powered by Infinity Pro Thermal Analysis software, a simple Windows-based platform that provides all the essential features needed to analyze and interpret your thermal data.

Key Features

True Hang-Down Balance Design

Industry-leading stability, sensitivity, and long-term drift resistance for reliable and repeatable measurements without the need for buoyancy corrective experiments.

High Sensitivity Microbalance

Sub-microgram-level accuracy across a broad temperature range, providing confidence in your thermal and mass loss data.

24-Bit Resolution

High-precision measurement of temperature, delta T, and weight with minimal noise and high digital fidelity.

Small Swept Volume Furnace Cup (7.5mL)

Enhances temperature uniformity and gas exchange efficiency.

Simultaneous TGA/DSC or DTA

Perform thermogravimetric and calorimetric analyses in a single run— ideal for decomposition, oxidation, and phase transitions.

Dual Purge Gas System

Separate channels for purge and protective gases allow for fine control of the experimental atmosphere.

Broad Temperature Range

Furnace operation up to 1500°C under inert, oxidizing, or reducing gas environments.

Motor-Driven Furnace Lift

Ensures automated, smooth movement of the furnace for consistent sample positioning.
