Preparative Supercritical Fluid Extraction System

Model: SFE-Pre

The FLOSN SFE-Pre is designed for preparative extraction and process scale-up studies. The proposed floor-standing platform combines two extraction vessels with higher-capacity CO₂ delivery and independently conditioned separation stages. Removable baskets and assisted closure handling address the practical demands of larger sample loads, while the control system coordinates extraction, product recovery and depressurization. The intended use is the production of research quantities of botanical extracts, oils and other CO₂-soluble fractions, together with the evaluation of operating conditions before further scale-up.

FLOSN / PRODUCT FEATURES

Product Features

8 FEATURES

01Preparative Batch Capacity

A twin-vessel layout is proposed for larger research batches and systematic scale-up studies.

02Staged Separation

Two independently conditioned separators allow different recovery conditions to be investigated.

03Removable Loading Baskets

Basket handling supports repeatable packing and easier material changeover.

04Assisted Closure Handling

Mechanical lifting support is proposed for heavy closures. Access remains conditional on confirmed depressurization.

05Coordinated Process Control

The proposed controller sequences pumping, thermal stages, pressure regulation and product collection.

06Optional CO₂ Recovery

A dedicated recovery package can be assessed against solvent consumption, utility loads and batch frequency.

07Accessible Pump Service Area

The lower base separates pump maintenance from vessel loading and extract collection.

08Scale-Up Data Capture

Logged process conditions support comparison across batch sizes; extraction yield must be measured independently.
