1. The freezing point osmometer is an instrument designed to measure the freezing point of solutions.

2. Atomic Absorption Spectrophotometry(AAS) and gas phase osmometer were conducted to analyse the chemical composition and osmotic pressure of seminal plasma of cultured golden trout and Japanese eel.

3. LBSJ-B freezing point osmometer is a kind of intelligent instrument using microprocessor. It can automatically test, correct, digital show and print the tested results.

4. Consequently the effective osmotic pressure that it exerts on biological membranes is far less than its osmotic pressure measured by an osmometer.

5. Objective:To determine osmotic pressure of human albumin with freezing point osmometer.

6. Through the indoor tests, calibrations and field tests of the fiber optic osmometer, an evaluation to the technical performances of the gauge is presented.
