Introduction

Small sample volumes, such as paediatric samples or scarce formulations, are hard to test when an osmometer needs large amounts. The compact all-in-one Löser i Osmometer M Micro Osmometer measures osmolality by freezing point in just 10 to 50 µl, with a built-in printer and scanner for documentation.

Key Benefits

Several daily bottlenecks ease when you work with the precise and GLP-ready Löser i Osmometer M Micro Osmometer.

Efficiency

A measurement takes about 1.3 minutes for 50 µl, and the instrument is ready about 3 minutes after switching on.

Accuracy

Calibration with distilled water and 300 mosm standard is very stable, and an optional 900 mosm point improves linearity at higher concentrations.

Safety and comfort

Single-use plastic tubes and code-protected user access support clean, controlled work.

Key Features

• Built-in thermal printer and scanner for sample and result documentation
• Touch-operated colour display in 7 languages
• Statistics (MV, SD, CV) and LOT function for sample numbers
• Code protection with log-in user administration and log function for GLP
• Variable 2nd and 3rd calibration points and selectable calibration intervals
• Automatic defrosting in stand-by to prevent needle or tube blocking

Solving Common Lab Problems

Running out of sample before you can test osmolality? The Löser i Osmometer M Micro Osmometer for daily lab work needs as little as 10 µl per measurement.

Need GLP-ready records? User log-in, change logging, a real-time clock and the built-in printer document every result.
