Restriction of Use

NEVER use the Biohit Prospenser 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 Biohit Prospenser and reagent are 15°C to 40°C

Before Using the Biohit Prospenser

Check that the instrument has not been damaged in transit.

Assembly

The Biohit Prospenser 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 Biohit
Prospenser is assembled to the container.
The assembled Biohit Prospenser is screwed to the reservoir using gentle hand torque applied to the
Biohit Prospenser'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
Fill the reservoir to approximately 50 mm below side neck aperture.
Place a container under the Biohit Prospenser 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 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 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 Biohit
Prospenser is not in use it is recommended that the anti-drip tap is closed.
