The Freeze-Drying System

PRACTICAL OPERATING TIP. REFER TO YOUR CONTROL SYSTEM OPERATOR’S MANUAL
FOR SPECIFIC DETAILS REGARDING THE OPERATION OF YOUR UNIT.

Components and Subsystems

Before operating your LyoStar™ 3 for the first time, take a few moments to familiarize
yourself with the lyophilizer’s components and subsystems. The LyoStar™ 3
lyophilizer consists of the following main components:

Product drying chamber.

•

Product shelves.

•

Ice condenser.

•

Shelf heat-transfer system.

•

Stoppering system.

•

Condenser cooling system.

•

Removable spool piece for optional installation of TDLAS apparatus.

•

Isolation valve.

•

Refrigeration system.

•

Vacuum system.

•

Aeration and vacuum level control.

•

Electrical system and associated wiring.

•

Control system software and related hardware components.

•

Tunable diode laser absorption spectroscopy (TDLAS) is a method of measuring the concentration of a gas or gas component.
