Advanced® Model 2020 Multi-Sample Osmometer

Advanced Instruments Osmometer, Model 2020, for Osmolality Measurement

The Advanced Instruments Model 2020 Micro Osmometer determines the osmolality of solutions using freezing point depression (FPD). It is ideal for serum, urine or other bodily fluids in clinical applications; and media or formulations in pharmaceutical, biotech or industrial applications. The Model 2020 can process up to 20 samples at one time.

Automated, multi-sample, designed to process a 20uL sample with a 90-second test time. The Model 2020 provides maximum productivity, accuracy and reliability.

• Up to 20 samples at one time
• 20 uL sample size is ideal for applications where the sample quantity is limited.
• Stat sample capability
