AELAB JS-III Gel Strength Tester for Precise Gelatin Bloom Strength Measurement

Overview

The AELAB JS-III Gel Strength Tester is mainly used to measure the gel strength of gelatin under stipulated environmental conditions. The gel strength of gelatin is an important indicator to reflect the technological level of gelatin production and control the production quality of gelatin.

The JS-III system includes the host of the gel strength tester, the precise constant temperature monitoring water tank of model HW-III, and the ZL-III efficient refrigerating machine. It meets all requirements for the measurement time limit in the Pharmacopoeia of Edition 2015 and dynamically monitors the press-in depth error of the probe throughout the testing process.

⚙️ Design & Construction

The AELAB JS-III Gel Strength Tester is engineered with an intelligent LCD interface, precision displacement system, and regulated water bath structure. The thermostatic bath maintains 5–60 °C with ±0.1 °C accuracy, supported by a magnetic circulating water pump for uniform heat distribution. A high-precision temperature sensor ensures consistent measurement conditions, while the full-automatic frequency-conversion refrigeration system stabilizes the bath rapidly for repeated testing. The integrated cylinder assembly and standardized gel bottles ensure reproducible penetration geometry for high-quality Bloom strength determinations.

🔬 Working Principle / Testing Method

The JS-III applies a controlled downward probe movement into a gelatin sample after defined conditioning. The system records penetration depth, force (Bloom g), and stroke displacement with ≤±0.1 mm error. The embedded controller interprets the real-time force curve to determine Bloom strength. Users may select single-step, auto, maintaining, or circular sampling modes. Two-speed penetration modes (normal and high-speed) enable precise testing across a variety of gelatin hardness profiles.

💡 Key Advantages

• Wide 5–1000 Bloom measurement range for pharmaceutical, food, and industrial gelatin testing
• Programmable sampling depth from 1–60 mm ensures reproducibility across gel types
• Rapid bath stabilization to 10 °C in under 40 minutes for efficient workflow
• Multiple sampling speeds (0.1–2 mm/s) for flexible characterization of gel textures
• Automatic probe depth monitoring eliminates sampling deviation and operator error
• High-speed measurement mode enhances throughput for batch QC operations
• Integrated temperature-controlled environment ensures compliance with Pharmacopoeia gel conditioning requirements

🔗 Connectivity & Integration

The JS-III supports standard data printing, on-board data storage, and experimental data recording. The system includes automatic fault diagnostics, sensor protection, and non-linear error correction, ensuring GLP-aligned traceability and reliable long-term use.
