Osmometer Model 3900

Advanced Instruments 3900: The Multi-Sample Osmometer for Maximum Productivity

The Advanced Instruments 3900 osmometer is a state-of-the-art device designed to automate laboratory testing, providing an efficient solution for laboratories handling moderate to high sample volumes. Using freezing point depression technology, it provides accurate determination of the total concentration of solutions, which is essential for a variety of clinical, pharmaceutical and industrial applications.

The Advanced Instruments 3900 is capable of processing up to 30 samples per hour unattended, allowing laboratory staff to focus on other tasks. This high processing capacity is made possible by its comprehensive data management system, which includes an integrated printer and easy connectivity to an optional barcode scanner. The barcode scanner ensures positive sample identification, minimising transcription errors and improving overall laboratory efficiency.

One of the major advantages of the Advanced Instruments 3900 is its automatic calibration. Unlike other devices that require manual adjustments, the 3900 uses a microprocessor to perform automatic calibration adjustments, simplifying the process and ensuring accurate results every time. In addition, its frost-free cooling chamber eliminates the need for routine maintenance, reducing downtime and increasing productivity.

The Advanced Instruments 3900 is also designed to be flexible and adaptable to the specific needs of each laboratory. It offers a comprehensive range of reporting capabilities, allowing users to customise reports to suit their specific requirements. In addition, its STAT capability allows tests to be interrupted at any time to process priority samples, which is essential in laboratory environments where time is a critical factor.

In terms of performance, the Advanced Instruments 3900 offers exceptional accuracy and repeatability. It is capable of measuring samples in a range of 0 to 4000 mOsm/kg H2O, with a resolution of 1 mOsm/kg H2O. Its linearity is less than ±0.5% in the low range and less than ±1.0% in the high range, ensuring accurate and reliable results every time.

The Advanced Instruments 3900 osmometer is an essential tool for any laboratory looking to maximise productivity and accuracy. With its features, automatic calibration and low maintenance, it offers a complete solution for laboratory testing, ensuring accurate and reliable results every time.
