It is an awesome and time saving equipment, I love it to the core


Average Rating 3.7

Application Area:

Analyze the osmotic strength of metabolite in urine, body fluids and serum

It is very effective at use and gives accurate results. Though at times it requires some voltage of power for it to work efficiently. At times when two samples of the same concentration are fun, there are slight variations. In terms of its use, it is very easy to use and understand. The one I'm working with is still working well, so I don't know it's aftercare.

With more than 50 years of experience KNAUER is one of the pioneers in the field of osmometry.

The company´s knowledge and passion for this technique is reflected also in its newest product. The K-7400S Semi-Micro Osmometer allows fast and easy analysis of aqueous liquids. Using the proven technology of freezing point depression, the device determines the total concentration of all dissolved particles of a solution and displays the result in a single value.

Users of the new KNAUER Instrument can choose the sample volume according to their needs in a range between 50 and 150 µl. Depending on the individual sample's specification, measurement temperatures can be adjusted to get precise and reproducible results. The acquired data can optionally be recorded via the EuroOsmo 7400 software. It also allows control of the device and plots the temperature curve of each measurement.

Due to the user-friendly menu navigation as well as the robust design, the quiet K-7400S is suitable for routine use in analytical labs and for quality control in the industrial sector.

Available features:

  • variable sample volume between 50 – 150 µl
  • Software EuroOsmo 7400 for control and data management
  • Easy and fast measurement of solutes
  • Robust and compact design
  • Suited for daily lab routine analyzes
