Vivaspin® 4 ml – Introduction
Storage conditions|shelf life
Vivaspin
®
4 ultrafiltration spin columns
should be stored at 15 – 30°C. The devices
should be used before the expiry date
printed on the box.
Introduction
Vivaspin
®
4 ml concentrators are disposable
ultrafiltration devices for the concentration
of biological samples. Maximum initial
sample volumes range from 1 ml to 4 ml.
They can be effectively used in either swing
bucket or fixed angle rotors accepting
15 ml conical bottom centrifuge tubes.
The patented vertical membrane design
and thin channel filtration chamber (US
5,647,990, second patent pending) minimises membrane fouling and provides high
speed concentrations, even with particle
laden solutions. Vivaspin
®
4 is available with
the high flux polyethersulfone membrane
range which is recommended for most
solutions.
The Vivaspin
®
4 product line
includes 1 cutoffs (Molecular Weight Cutoff,
MWCO):

4 10K filter devices are for in vitro
diagnostic use and can be used to concentrate serum, urine, cerebrospinal fluid, and
other body fluids prior to analysis. The
Vivaspin
®
4 devices are supplied non-sterile
and are for single use only.
Operation
1. Select the most appropriate membrane
for your sample. For maximum recovery
select a MWCO at least 50% smaller than
the molecular size of the species of interest.
2. Fill concentrator with up to maximum
volume shown in table 1. (Ensure lid is fully
seated).
3. Insert assembled concentrator into
centrifuge (when fixed angle rotors are
used, angle concentrator so that the
printed window faces upwards | outwards).
4. Centrifuge at speeds recommended
in table 2 taking care not to exceed the
maximum g force indicated by membrane
type and MWCO.
5. Once the desired concentration is
achieved, (see tables 3a and 3b, for a guide
to concentration times), remove assembly
and recover sample from the bottom of
the concentrate pocket with a pipette.
The filtrate tube can be sealed for storage.
Desalting | Buffer exchange
1. Concentrate sample to desired level or
at least 5+.
2. Empty filtrate container.
3. Refill concentrator with an appropriate
solvent.
4. Concentrate the sample again and repeat
the process until the concentration of
contaminating microsolute is sufficiently
reduced. Typically 3 wash cycles will remove
99% of initial salt content.

Usage Tips
4. Chemical Compatibility
Vivaspin
®
concentrators are designed for use
with biological fluids and aqueous solutions.
For chemical compatibility details, refer to
table 4.
1. Flow Rate
Filtration rate is affected by several parameters, including MWCO, porosity, sample concentration, viscosity, centrifugal force and
temperature. Expect significantly longer spin
times for starting solutions with over 5% solids. When operating at 4°C flow rates are
approximately 1.5 times slower than at 25°C.
Viscous solutions such as 50% glycerine will
take up to 5 times longer to concentrate
than samples in a predominantly buffer
solution.
2. Pre-rinsing
Membranes fitted to Vivaspin
®
concentrators
contain trace amounts of Glycerine and
Sodium azide. Should these interfere with
analysis they can be removed by rinsing fill
volume of buffer solution or deionised water
through the concentrator. Decant filtrate
and concentrate before processing sample
solution. If you do not want to use the
pre-rinsed device immediately, store it in the
refrigerator with buffer or water covering
the membrane surface. Please do not allow
the membrane to dry out.
3. Sterilisation
Polyethersulfone membranes should not
be autoclaved as high temperatures will
substantially increase membrane MWCO.
To sterilise, use a 70% ethanol solution or
sterilising gas mixture.
4. Chemical Compatibility
Vivaspin
®
concentrators are designed for use
with biological fluids and aqueous solutions.
Refer to the chemical compatibility table on
