General warning
2.5 Residual risks
The instrument has been developed and manufactured using the latest technological
advances. Nevertheless, risks to persons, property or the environment can arise if
the instrument is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual
dangers.
2.5.1 Faults during operation
If a device is damaged, sharp edges or exposed electrical wires can cause injuries.
uRegularly check device for visible damage.

Büchi Labortechnik AG Safety | 2
Operation Manual Lyovapor™ L-200/L-200 Pro 11/100
uIf faults occur, switch off the device immediately, unplug the power cord and
inform the operator.
uDo not continue to use devices that are damaged.
2.5.2 Damage to the ice condenser
Damage to the ice condenser leads to coolant leakage and failure of the instrument.
uWait until the ice is completely thawed.
uDo not use mechanical means to remove ice from the ice condenser.
2.5.3 Glass and acrylic breakage
Broken glass and acrylic can cause severe cuts.
Damaged glass and acrylic components may implode if subjected to a vacuum.
Minor damage to the ground joints impairs the sealing effect and may therefore
diminish sublimination capacity.
uHandle the flask and other glass and acrylic components carefully and do not
drop them.
uAlways place the flasks in a suitable holder when they are not mounted on the
Lyovapor™.
uAlways visually inspect glass and acrylic components for damage every time they
are to be used.
uDo not continue to use glass and acrylic components that are damaged.
uAlways wear protective gloves when disposing of broken glass and acrylic.
2.5.4 Low internal pressure
Evacuating the system reduces the pressure in the drying chamber. This reduced
pressure can cause glass and acrylic components to implode.
uMake sure that all glass and acrylic components are free of damage.
2.5.5 Cold and hot surfaces
The condenser coil and probes can be extremely cold. Heatable shelf areas can be
extremely hot. If touched, hot and cold surfaces can cause skin burns.
uDo not touch cold or hot surfaces or liquids and/or wear suitable protective
gloves.
2.6 Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
uAlways wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
uMake sure that the personal protective equipment meets the requirements of
the safety data sheets for all chemicals used.
2.7 Modifications
Unauthorized modifications can affect safety and lead to accidents.
uUse only genuine BUCHI accessories, spare parts and consumables.
uCarry out technical changes only with prior written approval from BUCHI.
uOnly allow changes to be made by BUCHI service technicians.

Operation Manual Lyovapor™ L-200/L-200 Pro 13/100
3 Product description
3.1 Description of function
The Lyovapor™ is a freeze-dryer in which frozen samples can be gently dried.
The basis of freeze-drying is sublimation. Sublimation refers to the process whereby
a substance transforms directly from the solid to the gaseous state.
The physical process of sublimation can be explained using the solvent water as an
example.
The water is frozen.
The frozen water is transformed into the gaseous state under vacuum at a
pressure below the triple point.
Thus, freeze-drying takes place in three phases:
1. Freezing phase: the sample is frozen at atmospheric pressure.
2. Main drying phase: heat is applied to the frozen sample under a vacuum. The
frozen water is removed by sublimation.
3. Secondary drying phase (only possible with heatable shelves): the trace levels
of water remaining are removed by heating.
The Lyovapor™ consists of an ice condenser and various top-mount drying racks. The
top-mount drying racks can be chosen to suit the availability of the sample being
dried and the requirements of the end product.
The following top-mount drying racks can be used:
Non-heatable and heatable shelves in rack
Trays in rack
Top-mount rack with manifold valves
3.1.1 Freezing phase
In the freezing phase, the aqueous preparation is transformed to a solid state.
Freezing takes place under atmospheric pressure using a separate freezer, a liquid
nitrogen bath, or a mixture of dry ice and alcohol.
The end of the freezing phase is reached as soon as the water contained in the
preparation has fully crystallized.
3.1.2 Main drying phase
In the main drying phase, the ice crystals are removed from the preparation by
sublimation. Sublimation in the Lyovapor™ takes place under a vacuum with the
addition of thermal energy.
To create the vaccum, the pressure is lowered to the level required for sublimation.
For water that is: less than 6.11mbar.
As the ice condenser is colder than the preparation being dried, the vapour pressure
in the area of the ice condenser is lower than in the area of the preparation. The
water vapour escaping from the preparation therefore flows towards the ice
condenser. The water vapour condenses on the coil of the ice condenser.
If a manifold-valve rack is used, heat transfer takes place by convection and
radiation from the surroundings. Control of the thermal energy transferred is then
difficult.

3 | Product description Büchi Labortechnik AG
14/100 Operation Manual Lyovapor™ L-200/L-200 Pro
If using a drying chamber with heatable shelves, heat transfer takes place by direct
contact. The temperature of the heatable shelves is controllable. Control of the
thermal energy transferred is then possible.
Controlling the heat transfer prevents the following critical temperatures for
amorphous and crystalline materials to be reached:
the glass transition temperature Tg' of the frozen preparation
the collapse temperature Tc.
the eutectic temperature Teu.
Above the glass transition temperature and the collapse temperature, the viscosity
of the frozen preparation increases. The increased viscosity leads to the collapse of
the preparation's matrix structure.
Above the eutectic temperature, the preparation melts.
During the main drying phase, the product temperature must remain below the
collapse temperature for amorphous materials in the preparation.
Sublimation of the ice crystals progresses downwards from the surface of the
product. Above the sublimation boundary, the product is dry ("freeze-dried cake"),
while further inside the product is still frozen.
The end of the main drying phase is reached when all ice crystals have been
removed from the preparation.
After the main drying phase, the remaining fluid content in the preparation can still
be between 5 to 10%.
3.1.3 Secondary-drying phase
In the secondary drying phase, the unfrozen water is removed from the sample by
desorption. The secondary drying function is performed by the heatable shelves in
the drying chamber of the Lyovapor™.
In the secondary drying phase, the temperature of the heatable shelves is raised and
held for several hours.
The end of the secondary drying phase is reached when the residual moisture in the
sample is between 1% and 5% or the end point determination is succeeded.
