Osmo1® Single-Sample Micro-Osmometer

With the Osmo1 Single-Sample Micro-Osmometer, we’ve bundled together accurate and reliable osmolality measurement with ease-of-use for efficient patient sample analysis. Easily maintain regulatory compliance while ensuring the security and integrity of patient data with the Osmo1. Best for labs that process 10 or fewer samples per day or prefer a direct-draw instrument.

Highlighted features:
  • Gold-standard freezing point depression method technology
  • Low sample volume requirements
  • Supports CAP, CLIA, and HIPAA compliance

Overview

Industry Applications

Clinical

FOR CLINICAL LABS

Great for smaller clinical labs that test urine, plasma, serum and stool osmolality. The Osmo1 combines easy to use features and data management security options that help you stay in compliance.

PRODUCT FEATURES

ONE-STEP DIRECT SAMPLING

Simply aspirate sample and load the sampler into the Osmo1.

TOUCHSCREEN USER INTERFACE

The Osmo1 is easy-to-use with an intuitive, color-coded menu-driven operating system, with multi-language capability.

SMALL SAMPLE SIZE

Requiring only 20 µL of sample, Osmo1 is ideal for sample limited applications.

ON-BOARD PRINTER

With a simple drop-in paper design, Osmo1 allows for easy printing and archiving of test results.

INTEGRATED BARCODE SCANNER

The built-in proximity sensor enables traceable sample identification and reduces transcription errors.

2- OR 3-POINT CALIBRATION

Osmo1 offers the flexibility of a 2- or 3-point calibration to satisfy CLIA calibration verification requirements. The system is also factory-calibrated and ready-to-use, requiring recalibration only if quality control is out of specification or after maintenance.

BUILT-IN QUALITY CONTROL

Osmo1 calculates sample statistics instantly, can issue warnings when quality control is out of range, and allows tracking of quality control data over time with an exportable Levey-Jennings chart.

SECURE AND EFFICIENT DATA MANAGEMENT

The Osmo1 offers password protected user accounts and the ability to link sample ID and user ID to test results, for improved traceability. The system also stores the last 1,000 test records and 10,000 events for audit control.

CONNECTIVITY

The Osmo1 connects easily to LIS and data management systems via Ethernet connectivity. Multiple USB ports provide the ability to easily export data.

INDUSTRY LEADING ACCURACY AND PRECISION

Osmo1 utilizes the industry-preferred freezing point depression method to accurately and precisely determine osmolality.

BACKED BY COMPREHENSIVE SUPPORT

You can purchase any Advanced Instruments osmometer with complete confidence as every instrument is backed by a knowledgeable, experienced, and responsive customer support team.
