Vivaflow 50
Single module
1. Set up the system as illustrated in
Diagram 1. Note the positioning of the
flow restrictor on the return line.
2. Vivaflow membranes contain trace
amounts of glycerine and sodium azide.
To remove these chemicals and to check
the security of the tube connections,
it is recommended to rinse the module,
and to test the system at full pressure
before introducing the sample.
3. Place 500 ml deionised water in a suitable
reservoir. The Vivaflow sample|diafil-
tration reservoir (prod. no. VFA006) is
recommended.
4. Pump liquid through the system to purge
any air pockets. The recirculation rate
should be in the range 200–400 ml/min,
and suitable flow should exit the filtrate
line. If used, the pressure indicator (prod.
no. VFA020), should read approximately
2.5 bar.
5. Allow 400 ml to pass into the filtrate
vessel. Check for any leakage at tubing
connection points. Drain the system
and empty or replace the filtrate vessel,
(see recovery section). The system is now
ready for use.

Linked modules
1. Set up the system as illustrated in
Diagram 2. Link the required number of
modules by sliding the tongue and groove
edges together. Note the positioning of
the flow restrictor on the return line.
2. Use series interconnectors, (prod. no.
VFA031), to connect a single row of
modules. Detailed ordering information
for system components to be found of
page 7, Diagram 4.
3. In addition, use T-connectors, (prod. no.
VFA030), to connect two rows of modules
in parallel.
4. The flow path of the system can be con-
figured to suit the membrane|sample
combination. Most solutions are better
suited by modules connected in parallel.
Very low viscosity solutions favour mod-
ules connected only in series. Rinse the
system as detailed under single module
operation.

Diafiltration|Desalting
1. Set up the system as illustrated in
Diagram 3 for linked modules. If only
one module is required, connect it in
place of the linked modules.
2. Rinse the system as detailed previously.
3. Either place the solution to be purified in
the 500 ml sample|diafiltration reservoir
(prod. no. VFA006), or concentrate a
larger volume to 500 ml or less so that it
is fully contained in the 500 ml reservoir.
Ensure the reservoir lid is firmly closed.
4. Fill a large feed reservoir with exchange
solvent and pump sample through the
system as for concentration.
5. As the volume in the 500 ml reservoir
decreases, the vacuum created draws
exchange solvent through the feed line
from the larger reservoir. Over 99%
solvent exchange can be accomplished
with an exchange volume approximately
5 times the volume of the sample.
Diagram 3: Buffer exchange | diafiltration with Vivaflow 50

6 |
Concentration
1. Fill the feed reservoir with sample solu-
tion. When initial volumes larger than
500 ml are required, place 500 ml in
the sample|diafiltration reservoir, the
remaining volume in another suit-
able container and connect the vessels
as detailed in the diafiltration section.
Alternatively, use a larger container for
the entire sample volume and immerse
the feed and return lines directly into
the liquid.
2. Pump liquid through the system. The
recirculation rate should be in the range
200–400 ml/min, and suitable flow
should exit the filtrate line. If used, the
pressure indicator, (prod. no. VFA020),
should read approximately 2.5 bar.
3. Concentrate the sample to the desired
volume.
! Warning: Do not run the same section of
tubing through the pump head for longer
than six hours, over use of tubing will
result in significant pressure drop and
ultimately, failure.
4. When the desired volume has been
reached, reduce the recirculation rate
to 20–40 ml/min and recirculate the
concentrated sample for 1–2 minutes to
maximise recovery.
Recovery
1. Disconnect the feed line from the lid
of the 500 ml reservoir or when using
a different container, remove the feed
line from the sample.
2. Pump residual system volume back into
the reservoir|container. (When parallel
modules are used with viscous solutions,
ensure that all modules are empty by
pinching the tubing between each of
the stacks of modules in turn).
3. For a more complete sample recovery
rinse approximately 5–10 ml per module
of water or sample buffer through the
system, and recover as before.

Vivaflow 50R and Vivaflow 200
Operation Single Vivaflow 50R or
Vivaflow 200 Modules
Assembly and rinsing single module
1. Set up the system as illustrated above in
Diagram 5.. Note the positioning of the
flow restrictor on the return line. A set of
flow restrictors of different gauges (Prod-
uct No. VFA009), is available for use with
solutions of unusually high or low viscosity.
! Warning: Ensure Luer connections are
secure before operation.
2. Vivaflow membranes contain trace
amounts of glycerine and sodium azide.
To remove these chemicals and to check
the security of the tube connections, it is
recommended to rinse the module, and
to test the system at full pressure before
introducing the sample.
3. Place 500 ml deionised water in a
suitable reservoir.
4. Pump liquid through the system to purge
any air pockets. The recirculation rate
should be 200–400 ml/min, and suit-
able flow should exit the filtrate line. If
used, the pressure indicator should read
approximately 2.5 bar.
5. Allow 400 ml to pass into the filtrate
vessel. Check for any leakage at tubing
connection points.
6. Drain the system and empty or replace
the filtrate vessel (see Recovery section).
The system is now ready for use.

3. Note the positioning of a flow restrictor
on the return line from each Vivaflow 200
module. Vivaflow membranes contain
trace amounts of glycerine and sodium
azide. To remove these chemicals and to
check the security of the tube connec-
tions,
it is recommended to rinse the module,
and to test the system at full pressure
before introducing the sample.
4. Place 1 litre of deionised water in a
suitable reservoir.
5. Pump liquid through the system to purge
any air pockets. The recirculation rate
should be 500–900 ml/min, and suit-
able flow should exit the filtrate line. If
used, the pressure indicator should read
approximately 2.5 bar.
6. Allow 800 ml to pass into the filtrate
vessel. Check for any leakage at tubing
connection points.
7. Drain the system and empty or replace
the filtrate vessel (see Recovery section).
The system is now ready for use.
Diagram 7: Setting up two Vivaflow 200 units

Diafiltration|Desalting
1. Set up the system as illustrated in
Diagram 8.
2. Rinse the system as detailed previously.
3. Place the solution to be purified in a
suitable diafiltration reservoir. For vol-
umes up to 500 ml the Vivaflow 500 ml
sample|diafiltration reservoir (VFA006),
is recommended. Ensure the lid is firmly
closed.
4. Fill the large feed reservoir with exchange
solvent and pump sample through the
system as for concentration.
5. As liquid passes through the membrane,
the vacuum created in the diafiltra-
tion reservoir draws in exchange solvent
through the feed line from the large res-
ervoir. Over 99% solvent exchange
can be accomplished with an exchange
volume of approximately 5 times the
sample volume.
Concentration
1. Fill the feed reservoir with sample
solution.
2. Pump liquid through the system.
The recircu lation rate should be 200–
400 ml/min, (500–900 ml/min for two
modules), and suitable flow should exit
the filtrate line. If used, the pressure indi-
cator should read approximately
2.5 bar.
! Warning: Do not run the same section
of tubing through the pump-head for
longer than 6 hours, overuse of tubing
will result in significant pressure drop and
ultimately, failure.
3. Concentrate the sample.
4. When nearing the desired volume, reduce
the recirculation rate to 20–40 ml/min
and recirculate the concentrated sam-
ple for 1–2 minutes to increase sample
recovery.
Recovery
1. Remove the feed line from the sample.
2. Pump residual system volume back into
the reservoir|container.
3. For a more complete recovery, rinse
25–50 ml of water or sample buffer
through the system, and recover as
before.
