High-Pressure Phase Equilibrium View-Cell System

High-Pressure Phase Equilibrium View-Cell System

Model: HPA-PE

The proposed FLOSN HPA-PE provides a temperature-controlled, variable-volume view cell for research on fluid phase behaviour. A retained sapphire viewing aperture, controlled mixing and piston volume adjustment support observation of phase boundaries and equilibration. Upper and lower sampling interfaces can be configured for external composition analysis. Neither a visible interface nor a pressure plateau alone proves equilibrium.

FLOSN / PRODUCT FEATURES

Product Features

6 FEATURES

Visible Phase Interfaces

A narrow vertical aperture supports observation over the selected working height.

Controlled Sample Volume

Piston displacement adjusts the enclosed inventory volume for research scans.

Mix and Settle Sequences

Recipes separate mixing from the quiescent observation stage.

Phase-Specific Sampling Access

Upper and lower ports permit development of representative phase sampling.

Synchronized Phase Records

Images, volume position, pressure and temperature are recorded together.

Analytical Integration Options

Qualified sampling and transfer modules can connect to a separately selected analyzer.
