1. Summary
The purpose of this document is to provide the
appropriate method for identifying, installing and
using Sartorius Stedim Biotech Virosart
modules. The procedure should be strictly followed
to ensure operator safety and to maintain optimum
performance of Virosart HF filter elements.

Virosart HF filter elements with the following part
®
numbers:
3VI--28-HC-SF (Virosart
®
3VI--28-MC-SF (Virosart
®
All Virosart HF process modules have sanitary inlet &
®
outlet connections.
2. Labeling of Virosart HF Process Modules
®
The type, order code, lot number and serial number are
imprinted on the outer support of the housing of the
Virosart HF process module. In addition these specifi-
®
cations are printed on the labels of the plastic bag and
the cardboard box. The direction of venting is indicated
by an arrow on the module as well as all inlet, venting
and outlet connections are labeled with the respective
purpose.
3. Installation of Virosart
®
Virosart HF process modules are connected to the
®
processing line at the inlet and outlet via triclamp
(please do not forget the gaskets!) connections. To
ensure appropriate wetting a pressure indicator at inlet
and outlet connection should be used as well as
a pressure regulator (e.g. diaphragm valve) at the out-
let connection (see picture below). It is recommended
to connect a valve (e.g. diaphragm valve) followed by a
venting filter (e.g. Sartofluor
to the vent connection via triclamp.

4. Wetting Virosart HF Process Modules
®
(In the direction of filtration)
Before every integrity test or operation, the entire
system needs to be rinsed to ensure that it is particle-
free as well as for complete wetting of the membrane
and proper use of the whole filter capacity. Incomplete
wetting might result in failed integrity testing.
For proper wetting of the membrane, back pressure
is required as indicated in paragraph 3.
To rinse the filter element, open the connected valve
at the vent connection and fill the housing with WFI.
Outlets placed upwards will ensure air elimination.
To ensure that all the air has been removed from the
lumen, keep the valve in front of the venting filter
opened during the whole flushing procedure. Start
rinsing the filter at an inlet pressure of 2.5 bar | 36 psi
against an outlet pressure of 2.0 bar | 29 psi (set by the
connected diaphragm valve). Rinse the filter element
for >20 min under these conditions to insure proper
wetting for a following pre-use integrity test.
If no pre-use integrity test will be performed, flushing
without back pressure will be sufficient for operation.
The housing can be drained by opening the outlet
valves and using compressed air or nitrogen at a maxi-
mal pressure of 0.5 bar | 7 psi in the direction of filtra-
tion. It can also be drained by simply opening the
valves, allowing the solution to drain out by gravity
flow. Outlet valves placed downwards will ensure
complete draining. After the housing is empty, close
all the valves. After the Virosart
according to the instructions, it is thoroughly wetted.
5. Integrity Testing of Virosart
It is very important to follow the wetting procedure for
Virosart HF to make sure that the filter is wetted out
®
completely prior to the integrity test. The integrity test
of a Virosart HF filter must be done using an automated
®
integrity test unit, preferably the Sartocheck
test unit. Before performing an integrity test the valve
at the vent connection has to be closed to avoid air
penetration within the connected air filter. When using
a Sartorius Stedim Biotech Sartocheck
system, the diffusion test can be performed automati-
cally, recording the corresponding integrity test data.
The test pressure for diffusion testing is 4.5 bar |
65.25 psi with a stabilization as well as testing time of
5 min. Certain applications (e.g. single-use transfer
sets) may require a reduced test pressure. In this case
diffusion testing can be executed at 2.5 bar | 36.3 psi
with a stabilization as well as testing time of 5 min. For
additional information on how to perform an automatic
integrity test please see our installation and operating
instructions for the Sartocheck

7. Filtration with Virosart

Virus filtration with Virosart
the end of the purification process prior to the last
buffer exchange | form and fill. The protein solution
which is subject to the virus filtration must be free of
aggregates, host cell protein & DNA to avoid premature
blockage of Virosart HF. Even if these contaminants
®
should be removed either during the initial recovery
process or latest during the polishing process of the
target molecule, small amounts might be sufficient to
cause premature blockage of the final virus filter.
To prevent this, an efficient pre-filtration step, such as
the Virosart Max, might be required as protection for
®
the Virosart HF. The optimum pre-filter to final filter
®
ratio has to be identified during development of this
process step. To make full use of the filtration area, the
lumen must be vented completely free of air. To do this,
keep the valve connected to the vent filter open during
the whole operation. Then apply the desired filtration
pressure. The pre-filter should be used in-line with the
final virus filter under the same conditions.
The Virosart HF can be operated at any pressure from
®
1 bar up to 5 bar. The filter qualification was performed
at an operating pressure of 2 bar | 29 psi to meet cus-
tomer standard requirements. The flow rate achieved
through the Virosart HF during the filtration is a
®
function of the purity of the feed stream, the target
molecule size and concentration. The flow rate might
decline with the progress of filtration and indicate
the respective blockage of the filter. After filtration the
Virosart HF module can be flushed to maximize pro-
®
tein transmission. Therefore please flush the module
with 10 L/m² of buffer.
8. Changing out the Virosart
The Virosart HF process module must be changed,
®
at the latest, when the maximum allowable differential
pressure is reached or when the validated process
volume has been processed over the filter.
9. Applications Support
If required, please contact your local Sartorius Stedim
Biotech representative to obtain further information
on technical data, product integrity testing or general
information concerning specific applications. Our ap-
plication specialists from Purification Technologies
will gladly assist in your filtration trial work if needed.
Moreover our validation service and support team
are always available to assist in questions concerning
product and process validation, as well as training of
staff and optimization of filtration processes.
10. Return of used filter elements
If you wish to return used filter elements to Sartorius
Stedim Biotech for inspection, it is necessary to
decontaminate and sterilize them prior to shipment.
This procedure has to be documented in the return
shipment form, available from your local Sartorius
Stedim Biotech representative. This documentation
is required by country law. Returned filter elements
cannot be handled unless the appropriate return
shipment form is completed.
11. Liability
Sartorius Stedim Biotech cannot assume liability if
Virosart HF filter elements are subject to improper
®
use. In the interest of product development we
reserve the right to make changes.
Thank you for working with Sartorius Stedim Biotech,
we appreciate your business.
