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.
