Laboratory osmometer K-7400S

microsample

KNAUER is one of the pioneers in the field of osmometry and known for its reliable and user friendly instruments for many decades. Our freezing point osmometer K-7400S allows the easy and fast determination of the osmolality of various aqueous solutions. Also, the freezing point depression of the samples can be read. The proven technology of freezing point determination in combination with the robust and intelligent design of the device allows reproducible measurements. The instrument is equipped with a peltier cooler and an integrated microprocessor controlling the automated measurement. The freezing point osmometer is a standalone device that optionally can be equipped with a printer. Furthermore, the device can be controlled via the EuroOsmo 7400 software. The software automatically plots the temperature curve for each measurement and calibration and allows saving of the measured values. In addition, the data can optionally be exported into various file formats for archival storage. The measurement specifications of the KNAUER Semi-Micro Osmometer K-7400S comply with the requirements of the European Pharmacopoeia for osmolality (Ph. Eur. 2.2.35, 10/2021) in the pharmaceutically relevant range of 0-400 mOsmol/kg. KEY FEATURES Made in Germany 60 years experience fast measurements TECHNICAL DATA Technical parameters Sample volume - 50 - 150 µl Osmolality range - 0 - 2000 mOsmol/kg Resolution - osmolality: integer value without decimal part, e.g. 850 mOsmol temperature: value with three digits, e.g. -1.576 °C Test time - ~ 2 min Precision - SD ≤ 4 mOsmol/kg [0 — 400 mOsmol/kg] RSD ≤ 1 % [400 — 2000 mOsmol/kg]
