Freeze Dry Process
Freeze drying is an important process in sample preparation and
for the preservation and storage of biologicals, pharmaceuticals
and foods. Of the various methods of dehydration, freeze drying
(lyophilization) is especially suited for substances that are heat
sensitive. Other than food processing (e.g., coffee, whole dinners),
freeze drying has been extensively used in the development of
pharmaceuticals (e.g., antibiotics) and preservation of biologicals
(e.g., proteins, plasma, viruses and cell lines). The nondestructive
nature of this process has been demonstrated by the retention of
viability in freeze dried viruses and microorganisms.
Freeze drying is a process whereby water or other solvent is
removed from frozen material by converting the frozen water
directly into vapor without the intermediate formation of liquid
water. The basis for this sublimation process involves the
absorption of heat by the frozen sample in order to vaporize the
ice; the use of a vacuum pump to enhance the removal of water
vapor from the surface of the sample; the transfer of water vapor to
a collector; and the removal of heat by the collector in order to
condense the water vapor. In essence, the freeze dry process is a
balance between the heat absorbed by the sample to vaporize the
ice and the heat removed from the collector to convert the water
vapor into ice.

Chapter 1: Introduction
Freeze Dry Rates
The efficiency of the freeze drying process is dependent upon the
surface area and the thickness of the sample, the collector
temperature and vacuum obtained, the eutectic point and solute
concentration of the sample. It is important to remember these
factors when trying to obtain efficient utilization of your freeze dry
system. A listing of selected materials and their approximate
drying times are shown in Table 1 for your reference.

Urea -7 -40 10
Blood Plasma -10 to -25 -40 16

Influenza Vaccine -30 -50 24

Vegetable Tissue -50 -80 60
*Total sample quantities are contingent on various freeze dryer capacities.
Up to the point of overloading the system, the greater the surface
area of the sample, the faster the rate of freeze drying. By contrast,
for a given surface area, the thicker the sample the slower the rate
of freeze drying. This is based on the fact that the heat of
sublimation is usually absorbed on one side of the frozen sample
and must travel through the frozen layer to vaporize water at the
other surface. In addition, as the sample is freeze dried, the water
vapor must travel through the layer of dried material. The thicker
the sample, the greater the chance that the dried layer may collapse
which would cause an additional decrease in the rate of freeze
drying.
The surface area and thickness of the sample can usually be
ignored when each sample contains only a few milliliters.
However, for larger volumes, the samples should be shell frozen to
maximize the surface area and minimize the thickness of the
sample. The volume of the freeze dry flask should be two to three
times the volume of the sample.

Chapter 1: Introduction
In order for lyophilization to occur, ice must be removed from the
frozen sample via sublimation. This is accomplished by the
collector and the vacuum pump. The collector, which should be at
least 15 to 20°C colder than the eutectic temperature (melting
temperature) of the sample, traps vapor as ice. Since the vapor
pressure at the collector is lower than that of the sample, the flow
of water vapor is from the sample to the collector. Since this vapor
diffusion process occurs very slowly under normal atmospheric
conditions, a good vacuum is essential to maintain an efficient rate.
In many applications, the maintenance of a vacuum of 0.133 mBar
or less is recommended.
The rate of freeze drying is directly proportional to the vapor
pressure and the vapor pressure is dependent upon both eutectic
temperature and solute concentration of the sample. For example,
a solution of sodium chloride and water would freeze dry at a
slower rate than pure water. The eutectic temperature of a sodium
chloride solution is about –21°C and at this temperature the vapor
pressure is about 1/16 that of water at 0°C. Although the eutectic
temperature is not dependent upon the concentration of sodium
chloride, the vapor pressure of the water would decrease as the
concentration of sodium chloride increased. This is due to the fact
that as the solute concentration increases, less of the surface area of
the frozen sample is occupied by water. In general, most solutions
or biological samples will have a eutectic temperature of –10 to
–25°C. However, if the sample contains a simple sugar such as
glucose or if the sample is animal or plant tissue, the eutectic
temperature may be as low as –30° to –50°C.
Freeze Dry Capacity
The volume of a sample that can be freeze dried at one time is
related to factors discussed previously and the size and design of
the freeze dry system. With any given instrument, the capacity is
based on the surface area of the sample; the eutectic temperature
and concentration of the sample; and the rate and amount of heat
transferred to the frozen sample. Of these factors, the eutectic
temperature is the most important factor in determining the amount
of sample that can be freeze dried at one time, particularly when
flasks are used. This is because as the eutectic temperature
decreases, the vapor pressure decreases but the rate of heat
absorption by the sample does not change. This tends to promote
melting of the sample which leads to a marked increase in vapor
pressure and ultimately overloads the collector and vacuum pump.
Samples that have eutectic temperatures of –20°C or lower should
be placed on the freeze dry system one flask at a time so that the
Product Service: Domestic 1-800-522-7658, International 816-333-8811

Chapter 1: Introduction
vacuum in the system may recover before adding another sample
to the system. If the vacuum does not recover, the capacity of the
freeze dry system has been exceeded and the sample should be
removed.
If there is a problem with a particular type of sample melting when
placed on the freeze dry system, dilution of the sample with more
water or providing some insulation around the flask to decrease the
rate of heat absorption by the sample may help. If the eutectic
temperature of the sample is –40 to –60°C, the freeze dry system
selected for use must be equipped with cascade type refrigeration
so that the collector temperature can be cooled to below –75°C, or
a dry ice/solvent trap may be used between the collector and the
vacuum pump.
Samples Containing Volatile
Substances
In certain cases the solvent in a sample to be freeze dried may
contain volatile components such as acetonitrile, methanol, acetic
acid, formic acid or pyridine. In addition to these substances
having an effect on the eutectic temperature, they may increase the
vapor pressure at the surface of the sample. Also, compared to
water, they will require the absorption of less heat for sublimation
to occur. Hence, samples that contain volatile substances will have
a greater tendency to melt, particularly when placed in flasks or
exposed to room temperature. If a sample containing a volatile
substance tends to melt when placed on a freeze dry system,
dilution of the sample with more water will help keep the sample
frozen. For example, a 0.2M solution of acetic acid is much easier
to freeze dry than a 0.5M solution.

Chapter 3: Getting Started
• Most common compounds used in freeze drying processes, if
allowed to enter the vacuum pump, will degrade the oil and
cause damage to the vacuum pump.
• Sugars and proteins typically will have minimal negative effect
on any of the materials of construction.
When using compounds in the Freeze Dryer that are hostile to the
materials of construction, it is imperative that the equipment is
thoroughly cleaned after use.
• Rubber and plastic components that have been exposed to
damaging compounds should be removed and flushed with
water.
• The oil in the vacuum pump should be checked often. It must
be changed if it is cloudy, shows particles or is discolored. The
useful life of vacuum pump oil can be extended if the vacuum
pump is operated for an extended period of time after a freeze
dry run. This allows contaminants to be purged from the hot
oil. This must be done with the inlet to the pump blocked off
to prevent air from free flowing through the pump. If the pump
is operated at an elevated vacuum level, (>10mBar) oil may be
expelled from the pump and damage could occur.
Another way to extend the life of the vacuum pump is to install an
optional secondary trap in the line between the Freeze Dryer and
the vacuum pump. Contact Labconco for ordering information.
With prudent maintenance the FreeZone Freeze Dry System will
provide years of service. Warranty on the affected parts will be
voided if maintenance has been obviously neglected. If you have
questions about using specific compounds in the Freeze Dryer,
contact Labconco Technical Service at 1-800-821-5525 or 816333-8811 or e-mail: labconco@labconco.com.

The following checklist should be followed prior to each use of
your Freeze Dryer:
1. Wipe the interior of the collector chamber with a soft cloth or
paper towel to remove any accumulated moisture.
2. Check the collector chamber drain hose to ensure that the hose
is free of moisture and that the drain plug is securely installed.
3. Using a soft, lint-free cloth or paper towel, wipe the collector
chamber lid gasket to remove any dirt and contaminants that
could cause a vacuum leak. Vacuum grease is not required on
the lid gasket to obtain a proper vacuum seal.

4. Remove the accessory drying chamber or manifold from the
connection port and using a soft, lint-free cloth or paper towel,
wipe the port gasket and sealing surfaces of the drying
chamber/manifold to remove any dirt and contaminants that
could cause a vacuum leak. Reinstall the drying chamber or
manifold on the port. Vacuum grease is not required on the
port gasket to obtain a proper vacuum seal.
5. Check that each sample valve is closed or in the “vent”
position.
Chapter 4: Using Your Freeze Dryer
Vacuum Pump Ballast Setting
Most vacuum pumps are equipped with a gas ballast mechanism.
The freeze dry process requires high vacuum (0.133 mBar).
Therefore, it is recommended that the gas ballast be closed during
the operation of the Freeze Dry System. If the gas ballast is left
open for extended periods of operation, the oil can be pumped out
the exhaust, causing the pump to fail.

Chapter 4: Using Your Freeze Dryer
Pre-Freezing Samples
Appropriate containers for freeze drying include ampules, serum
bottles, and wide mouth freeze drying flasks. Shell freezing of
samples is recommended for wide mouth freeze drying flasks.
Smaller samples in ampules and serum bottles may be frozen in a
freezer. The sample container size should always be at least two to
three times the sample size (i.e., 40 ml samples should be prepared
in 80 ml containers or larger). The temperature required for prefreezing is dependent on the characteristics of the sample. Prefreezing temperature typically is at least 10° to 20°C below the
eutectic or collapse temperature of the sample.
Adding Sample
The following procedure should be followed when using sample
valves in the freeze dry process:
1. Pre-freeze samples. Appropriate containers for freeze drying include
ampules, serum bottles, and wide mouth freeze drying flasks. Shell
freezing of samples is recommended for wide mouth freeze drying
flasks. Smaller samples in ampules and serum bottles may be frozen
in a freezer or in the center of the collector chamber. The sample
container size should always be at least two to three times the sample
size (i.e., 40 ml samples should be prepared in 80 ml containers or
larger).
2. Connect a pre-frozen sample to a sample valve on the drying chamber
or manifold using an adapter. Turn the plastic valve knob to the
“VACUUM” position to open the valve, which connects the attached
sample to system vacuum. The bevel on the knob should be
positioned toward the sample port to apply vacuum to the sample.

21
Chapter 4: Using Your Freeze Dryer
3. Before adding another sample, allow system vacuum to return
to 0.133 mBar or lower. Any combination of valves and
sample sizes may be utilized at one time provided that the
system vacuum and collector temperature remain sufficiently
low to prevent melting of the frozen sample.
4. When all the frost has disappeared from the outer surface of the
sample container and no cold spots can be detected by handling
the container, the sample is nearly dry. To be certain of low
final moisture content, dry the sample for several hours past
this point.
5. To remove a container after drying is complete, turn the plastic
knob on the valve to the “VENT” position, which closes the
valve and vents the container. Should backfilling with an inert
gas be required, connect the gas supply line to the vent port on
the valve before turning the plastic knob on the valve to vent
position. The sample container may now be removed. In the
vent position the bevel on the knob should point away from the
sample port.
6. Ampules may be flame sealed while connected to a valve by
using a sealing torch. Care must be taken not to burn the valve.
An insulation material placed between the valve and the torch
is recommended.
Shut Down
At the end of a run or when a sufficient amount of condensate
accumulates on the collector coil to obstruct the flow of vapor to
the collector chamber, the Freeze Dryer should be defrosted. First,
release system vacuum by turning the plastic knob on a valve to
the open position or by pulling the collector chamber drain plug
out of the drain hose. Now press the Vacuum Switch on the
control panel to turn the vacuum pump OFF. Turn OFF the Main
Power Switch on the right hand side of the cabinet.
Defrosting
The following procedure should be followed when defrosting the
collector coil:
1. Pull the collector chamber drain hose out from the left hand
side of the Freeze Dryer and remove the drain plug. Place the
drain hose in a suitable container to collect the condensate that
will melt off the collector coil.
2. Remove the collector chamber lid and allow ambient room air
to melt the ice. Dispose of the liquid appropriately.
3. Flush the collector chamber with water and wipe chamber dry.
22
Product Service: Domestic 1-800-522-7658, International 816-333-8811
4. If rapid defrost is desired, pour warm water over the collector
coil. Do not allow the liquid to enter the vacuum port on the
upper rear of the chamber.
5. Reinstall the drain hose plug and slide drain hose back into the
side of the cabinet. Dispose of the liquid appropriately.
Utilization of acid requires immediate cleaning
!
and neutralization after defrost or physical
damage to the collector chamber and collector

Chapter 5: Maintaining Your Freeze Dryer
Monthly:
1. The rubber components on the Freeze Dryer may eventually
deteriorate and require replacement. The effective life of
rubber parts depends upon both their usage and the surrounding
environment. Check all rubber hoses and gaskets and replace
any that show signs of hardening, permanent set or
deterioration.
2. Using a soft cloth, sponge or chamois and a mild, non-abrasive
soap or detergent, clean the acrylic chamber lid.
3. Using a soft cloth, sponge, or chamois and a mild, non-abrasive
soap or detergent, clean the exterior surfaces of the Freeze
Dryer. Liquid spray cleaners and polishes may be used on the
exterior surfaces. Do not use solvents to remove stains from
the exterior surfaces as they may damage the finish.
Annually:
1. Every 12 months, or more often if the Freeze Dryer is operated
in a dusty environment, the refrigeration system condenser
should be cleaned. Using a vacuum cleaner with brush
attachment, clean the condenser to ensure proper airflow for
peak performance.

Refer to the following if your Freeze Dryer fails to operate
properly. If the suggested corrective actions do not solve your
problem, contact Labconco for additional assistance.
Labconco Freeze Dry Systems that are clean, dry and without
samples attached should reach a vacuum of 0.133 mBar within 10
minutes and should achieve an ultimate vacuum of 0.033 mBar
within 18 hours when the refrigeration is operating. If the Freeze
Dryer does not obtain a satisfactory vacuum, perform the following
maintenance tests.
I. Vacuum Pump
First make sure that the vacuum pump operates. If it fails to
operate, check the electrical connections of the Freeze Dryer to the
power source and then check the electrical connection of the
vacuum pump to the Freeze Dryer. If the vacuum pump has a
power switch, make sure that it is turned on. If the vacuum is not
adequate when the vacuum pump is operating, proceed with the
following steps:
1. Check the oil and ensure it is clear and clean. If the oil
looks cloudy or has any particulates, replace the pump oil.
Sometimes it may be necessary to flush the pump with
clean oil several times. To flush the pump, run the pump 5
to 10 minutes to allow the oil to warm up. Drain the oil
and refill with clean oil. Repeat as necessary.
2. Check the oil level in the pump. Ensure it is filled to the
correct level.
3. Check vacuum hose connections from the pump to the
Freeze Dryer and try running the unit

Chapter 6: Troubleshooting
If vacuum problems continue, consider obtaining a second
vacuum gauge capable of reading a vacuum of 0.010 mBar.
It is often useful in determining if the vacuum pump is
operating properly and the vacuum sensor reading is
accurate.
4. Isolate the pump by disconnecting the vacuum hose from
the Freeze Dryer. Deadhead the pump by inserting the
vacuum sensor from a secondary vacuum gauge into the
end of the vacuum hose and observe the vacuum reading
obtained. Confirm that the pump is capable of achieving an
ultimate vacuum less than 0.010 mBar or approximately 10
microns. If an inadequate vacuum reading is obtained, the
pump has most likely failed and may need to be replaced or
rebuilt.
II. Gaskets, Tubing, Connections, Sample
Valves
1. Check all sample valves on the drying chamber/manifold
and ensure all valves are closed or in the vent position.
Check to ensure all fittings are tight and sealed properly
against the chamber. Inspect valves for cracks or cuts.
2. Inspect gasket(s) for cracks or defects. Ensure the gasket is
clean. Apply a thin coat of vacuum grease to the gasket.
Keep in mind too much vacuum grease can actually cause
leaks.
3. Check the drain line and ensure the drain plug is installed
and the tube appears to be in good condition.
4. Check all rubber vacuum tubing for signs of deterioration
or cracking.
5. Check all connections and make sure they are secure and
leak tight.
6. When checking the sample valves, pull as much vacuum as
possible. If a vacuum indication is displayed, wiggle or
rotate the valves and watch the gauge for any fluctuations.
Fluctuations can indicate a potential vacuum leak. If the
valve seems to be in good condition, remove the valve and
apply a thin coat of vacuum grease to the stem and the
outside sealing surface of the valve body, and reinstall the
valve. DO NOT APPLY VACUUM GREASE TO THE
SAMPLE VALVE GASKETS, WHICH SEAL TO THE
WALL OF THE DRYING CHAMBER. If the valve still
seems to be the source of the problem, remove the valve
