Restriction of Use
NEVER use the Zippette with:
• Liquids which are not compatible with PTFE, PVDF, FEP, Borosilicate glass, Alumina ceramic or might
attack Platinum-Iridium
• Hydrofluoric acid
• Liquids which contain solid particles
Temperature limits of Zippette and reagent are 15°C to 40°C

Before Using the Zippette

Check that the instrument has not been damaged in transit.
Assembly
The Zippette is packed with the dispense tube attached and the inlet feed tube removed. The 300mm
length of PTFE inlet tube provided should be trimmed to fit 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 is
assembled to the container.
The threaded platform base of the Zippette has a 30mm screw thread for use with the recommended
Jencons Safety amber reservoir 1.4 litre with side filler neck (Cat. No. 262-086). The assembled Zippette
is screwed to the reservoir using gentle hand torque applied to the Zippette'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.
Three adaptors are supplied to suit containers with a 33mm, 38mm or 45mm screw neck.
Operating Instructions
Priming Reservoir
It is recommended that you use the Jencons' squat anti-tip reservoir with safety side fill neck, available in
1.4 litre (Cat. No. 262-086) and 2.5 litre (Cat. No. 262-103) capacities. Fill the reservoir to approximately
50 mm below side neck aperture.
Place a container under the Zippette 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 lift-
ing it up about 25 mm. Repeat until steady, bubble free flow is dispensed.
Dispensing
After priming, the piston (4) should be left in the fully down position. To dispense a precise volume of fluid,
adjust the cursor (6) so that the cursor line aligns to the volume required. Draw in the required volume of
fluid 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 is not in use it
is recommended that the anti-drip tap is closed.
