7. Immediately close the cartridge and insert it into an instrument – it is important to prevent exposing
the soluon to room air since this will alter the results.
Transferring the control soluon: syringe with blunt p needle
Plain syringes (1cc or 3cc sterile syringes with blunt p needles) are recommended to transfer aqueous
control soluons from the ampule to the cartridge.
To use a syringe:
1. Place the end of the blunt p needle into the boom of the ampule.
2. Slowly remove approximately 1cc of soluon from the ampule into the syringe.
• If air is trapped between the leading edge of the soluon and the plunger, do not invert the
syringe to expel it; this will not aect soluon near the p of the syringe.
• If air bubbles are connually drawn into the syringe, or if a bubble is trapped near the p of the
syringe, discard the ampule and syringe.
3. Remove syringe from the ampule and expel one or two drops from the syringe.
4. Place needle into the sample cartridge and ll the cartridge to the ll mark.
5. Close cartridge and begin tesng immediately.
Transferring the control soluon: capillary tube
Plain capillary tubes are recommended to transfer aqueous control soluon from the ampule to the
cartridge. Capillary tubes with sucient ll capacity are required. For example, when lling a cartridge
that requires 95 µl, use a 150 µl capillary tube.
To use a capillary tube:
1. Place a clean, dry nger over one end of the tube and insert open end of the tube into the boom of
the ampule.
2. When the open end of the tube touches the boom of the ampule, p the ampule slightly. Remove
nger from the other end to allow lling by capillary acon. Completely ll the tube with the control
soluon.
3. Place a nger over the open end of the tube. Remove the tube from the ampule.
4. Place open end of the tube into the sample cartridge. Remove nger to allow the control soluon to
ll the cartridge to the ll mark.
5. Close cartridge immediately aer lling.
6. Tesng should be started immediately.
