Assembly
The Zippette Classic is packed with the dispense tube attached and the inlet feed tube removed. The 300
mm length of PTFE inlet tube provided should be trimmed to t your particular reservoir. The bottom end
should be cut diagonally at a length that is close to the bottom of the container when the Zippette Classic
is assembled to the container.
The threaded platform base of the Zippette Classic has a 30 mm screw thread for use with the
recommended squat amber reservoir 1.4 litre with side ller neck, see page 10 for ordering details. The
assembled Zippette Classic is screwed onto the reservoir using gentle hand torque applied to the Zippette
Classic’s threaded platform base only. Removal should also be by means of hand torque applied to this
same base.
Do not operate the piston until the unit is safely and fully mounted on the reservoir bottle.
Specification
Accuracy ≤±0.3% on maximum delivery and a precision ≤0.1%CV using distilled water at 20 °C.
Testing takes place according to DIN EN ISO 8655 using maximum nominal volume of distilled water at
20°C, with a uniform and smooth dispense action.

Instructions for Use
Operating instructions
Priming Reservoir
It is recommended that you use the VWR squat anti-tip reservoir with safety side ll neck, available in 1.4
litre and 2.5 litre capacities, see page 10 for ordering details. Fill the reservoir to approximately 50 mm below
side neck aperture.
Place a container under the Zippette Classic dispense tube (14). Move the cursor (6) to the bottom of the
scale to enable free movement of the piston. To move the cursor, simply press the button (7) on the cursor
sideways and slide up or down. The cursor will lock automatically into position as soon as you release the
button. Prime the unit with a few gentle up and down strokes, taking the piston right down and lifting it up
about 25 mm. Repeat until steady, bubble free ow is dispensed.
Dispensing
After priming, the piston (4) should be left in the fully down position. To dispense a precise volume of uid,
adjust the cursor (6) so that the cursor line aligns to the volume required. Draw in the required volume of
uid by lifting the piston slowly until the stop. To dispense, push the piston assembly down fully, slowly, until
it stops, allowing the liquid to be collected in an appropriate vessel. When the Zippette Classic is not in use it
is recommended that the anti-drip tap is closed.
User Calibration Procedure
Fine Adjustment
The gures quoted on our Test Certicate apply to the calibration of the Zippette Classic at full volume. The
Zippette Classic adjustment cap enables the user to ne calibrate for accuracy. Using the adjustment disc
tool that is held on the rear of the Zippette Classic body, change the factory calibration by turning the slot
on the printed top cap insert:-
Anti-clockwise to increase volume Clockwise to decrease volume
The graduations on the adjustment ring increase or decrease by the following volumes:-
Zippette Classic 50 ml 0.1 ml per line
Zippette Classic 30 ml 0.1 ml per line
Zippette Classic 10 ml 33 µl per line
Zippette Classic 5 ml 17 µl per line
Zippette Classic 2.5 ml 8 µl per line

General Maintenance
Maintenance/Cleaning
Note; All maintenance should be carried out wearing suitable eye protection and protective clothing. If in
doubt, consult your safety ofcer.
1. Make sure that the Zippette Classic is completely empty and turn the anti-drip tap to ‘Open’ position.
2. Place the instrument into an empty sink together with its reservoir. Unscrew the threaded platform base
from the reservoir and lift the dispenser’s intake tube carefully out of the reservoir, whilst tapping it
against the reservoir’s aperture to shake off any droplets from the intake tube.
3. Hold the dispense tube nozzle over the aperture of the reservoir and apply gentle piston strokes in order
to return any glass barrel contents into the reservoir.
4. Flush out remaining glass barrel contents with distilled water or a suitable solvent. This will preserve the
smooth action of the piston and free action of the inlet and outlet valves. If the inlet valve does stick and
is not freed by ushing, it may be freed by gently inserting a thin rod into the inlet aperture and gently
pushing the ball off its seating. Re-check unit for operation.
5. Empty the instrument completely after cleaning, and ush through with distilled water.
Sterilising/Autoclaving
Autoclaving is permissible at 121 °C 2 bar
after the normal cleaning procedure is carried
out. The cursor should be locked in the centre
of the adjustment slot before autoclaving.
Place the instrument on a cloth in order to
avoid contact with metal surface. Autoclave
the unit in its assembled status but with
the threaded ring completely loosened.
Autoclaving of the piston outside the glass
barrel will damage it. Cool slowly back to
ambient temperature before use.
Chemical sterilisation
The uid path components of the Zippette
Classic can be soaked overnight in a dilute
(1:1000) solution of sodium hypochlorite. (See
page 9 for disassembly procedure).

Disassembly Options/Cleaning
WARNING Do not use force in assembly or disassembly.
Disassembly should only be undertaken after the unit has been cleaned using the recommended cleaning
procedure. Wear protective clothing and goggles during disassembly.
1. Move the cursor (6) down the scale and undo the dispense sleeve cap (1) by turning anti-clockwise
andlifting.
2. The piston holder (2) is now exposed and the piston (4) is ready for removal. Remove the piston
assemblycarefully.
3. Clean the piston’s surface with a suitable cleaning solution. Do not use hard tools to scrape off residue
of reagent from the piston as this will damage the surface and will not seal with the glass barrel when
reassembled.
4. If it is necessary to clean or replace the graduated outer dispense sleeve (5) of your Zippette Classic, this
is carried out with the help of the supplied assembly tool (17).
a. Loosen the polypropylene threaded ring (9) on the base by approximately one turn.
b. Using the assembly tool (17), undo the top stop ring (3) by turning clockwise and lifting it out. You
can now lift off the dispense sleeve (5).
c. To remove the polypropylene protection sleeve (11) and borosilicate glass barrel (10), fully undo the
threaded ring (9), remove the polypropylene protection sleeve (11) and gently lift out the glass barrel
(10) for replacement or cleaning.
Note: Bevelled inside edge of barrel must be at the top end when tted.
d. Removal of FEP dispense tube (14); Firstly turn the anti-drip tap to the closed position.
Then remove dispense tube protection cover (15) in an upward direction allowing dispense tube (14)
to be pulled out of anti-drip shut-off valve assembly in direction indicated on pages 12 and 13.
e. Reassemble in reverse, make sure the front end of the dispense tube is clipped into the dispense tube
protection cover (15) from the underside.
f. Reassemble the remaining components following the above points in reverse order, making sure that
the FEP ‘O’ ring (12) is well located into its platform recess. Take special care not to damage the piston
when inserting it into the glass barrel.
g. Before tightening the threaded ring (9) fully onto the threaded platform base (13), rotate the
polypropylene protection sleeve (11) so that the tooth on its base locates properly into the notch on
the threaded ring (9).
h. After reassembling the instrument, prime with distilled water to ensure that assembly has been
correctly followed and the piston is working smoothly. Check that no leaks occur.

avec le réservoir ambré renforcé de 1,4litre avec col de remplissage latéral recommandé. Reportez-vous à
la page24 pour les informations de commande. Une fois le Zippette Classic assemblé, il doit être vissé au
réservoir par torsion manuelle légère sur la base de la plateforme letée uniquement. Le retrait s’effectue
également par torsion manuelle sur cette même base.
N’actionnez pas le piston tant que l’appareil n’est pas monté entièrement et en toute sécurité sur le
réservoir.

ZIPPETTE CLASSIC
Mode d’emploi
Instructions d’utilisation
Réservoir pour amorçage
Il est recommandé d’utiliser le réservoir renforcé anti-basculement VWR avec col de remplissage latéral,
disponible en capacités 1,4litres et 2,5litres. Voir page24 pour les informations de commande. Remplissez
le réservoir jusqu’à environ 50mm en-dessous de l’ouverture du col latéral.
Placez un récipient sous le tube de distribution du Zippette Classic (14). Déplacez le curseur (6) vers le bas
de l’échelle pour permettre le mouvement du piston. Pour déplacer le curseur, appuyez simplement sur
le bouton (7) sur le côté du curseur et faites-le glisser vers le haut ou vers le bas. Le curseur se verrouille
automatiquement en position dès que le bouton est relâché. Amorcez l’unité en tapotant délicatement
vers le haut et vers le bas, en déplaçant le piston bien droit vers le bas et en le soulevant d’environ 25mm.
Répétez l’opération jusqu’à ce qu’il soit stable en vous assurant que le ux distribué ne contienne pas de
bulles.
Distribution
Après l’amorçage, le piston (4) doit être laissé dans la position la plus basse. Pour distribuer un volume
précis de liquide, ajustez le curseur (6) an qu’il s’aligne sur le volume nécessaire. Arrêtez-vous au niveau du
volume de liquide requis en soulevant doucement le piston jusqu’à l’arrêt. Pour distribuer, poussez lentement
le piston complètement vers le bas jusqu’à ce qu’il s’arrête an de recueillir le liquide dans un récipient
approprié. Lorsque le Zippette Classic n’est pas utilisé, il est recommandé de fermer le robinet anti-goutte.
