SI Analytics Schott AVS Pro Automatic Sampler – High Throughput Viscometer

The SI Analytics Schott AVS Pro is a fully automated, PC-controlled viscometer system engineered for laboratories that require precision, reproducibility, and high-throughput viscosity measurement. Utilizing the proven principles of capillary viscometry, the AVS Pro delivers accuracy better than 0.1%, ensuring confidence in every measurement. Its versatility makes it indispensable across industries such as petrochemicals, polymers, pharmaceuticals, cosmetics, food, and beverages, where viscosity is a critical quality parameter.

With support for multiple viscometer types, including Ubbelohde, Ostwald, and Cannon-Fenske, and the ability to process up to 56 samples in fully automated workflows, the SI Analytics Schott AVS Pro combines laboratory efficiency with research-grade accuracy. Whether you are testing raw materials, monitoring production batches, or developing new formulations, this system offers reliable, continuous operation with minimal operator intervention.

At HiTechTrader, we provide refurbished and pre-owned AVS Pro systems, enabling laboratories to access cutting-edge technology at a fraction of the cost of new equipment. Every unit is carefully inspected, serviced, and performance-tested, so researchers can achieve dependable results without exceeding budget constraints. By making high-quality laboratory automation more accessible, we help organizations increase throughput, maintain compliance, and expand testing capabilities efficiently.

Vessel and Construction

The AVS Pro is built as a modular, PC-controlled system designed to integrate seamlessly into laboratory workflows. It can be configured with 1 to 4 measuring positions, allowing flexibility in throughput capacity. Depending on the configuration, the system can handle:

1. Up to 16 samples of 100 mL each, or
2. Up to 56 samples of 20 mL each.

This scalability makes the AVS Pro equally suitable for small-scale research labs and large-scale quality control facilities.

Closure and Sealing

To ensure sample integrity and eliminate contamination risks, the system incorporates automated rinsing and drying modules. Users can choose between sequential rinsing or a combined rinse-agent and drying process, optimizing workflows for different sample types. Automated sample handling reduces operator variability and ensures reproducible results across multiple test runs.

Operating Parameters

1. Measuring Range (Flow Time): Up to 999.99 seconds with 0.01-second resolution.
2. Accuracy: ±0.01 seconds in time measurement; viscosity reproducibility better than 0.1%.
3. Viscosity Range: Up to ~1200 mm²/s (depending on viscometer type).
4. Temperature Range: -40°C to +100°C with compatible SI Analytics thermostat baths.
5. Automation: 24-hour unattended operation supported.

With seamless integration into thermostat baths and automated dosing, the AVS Pro ensures precise temperature control and reliable sample conditioning, critical factors for high-quality viscosity measurement.

Accessory Compatibility

The AVS Pro is compatible with a wide range of Ubbelohde (DIN, ASTM, Micro), Ostwald, Micro Ostwald, and Cannon-Fenske viscometers, making it versatile for nearly any viscosity measurement application. The modular sample trays and dosing modules allow quick adaptation between high-volume testing and specialized sample runs.

Safe Operation Guidelines

The system is designed for continuous use in regulated environments. Its PC-controlled automation ensures compliance with GLP/GMP standards, while integrated data acquisition and reporting software provides traceable, documented workflows for quality assurance and regulatory audits. By automating rinsing, drying, and measurement, the AVS Pro minimizes operator exposure to chemicals while reducing human error in repetitive testing.

Applications

1. Polymers: Monitoring polyester, polyamide, and specialty plastic viscosities for consistency and performance.
2. Pharmaceuticals & Cosmetics: Profiling suspensions, gels, emulsions, and topical formulations.
3. Food & Beverages: Ensuring uniform texture and consistency in syrups, sauces, and other liquid products.
4. Research & Development: High-throughput testing of experimental compounds and formulations.
