4.2 BETWEEN-SPIN TIME DELAY (continued)
4.2.2 QBC Malaria Test
• If room temperature is less than 33 ºC (< 91 ºF), wait 1 min between spins.
• If room temperature is 33 - 35 ºC (91 - 95 ºF), wait 3 min between spins.
• If room temperature is 36 - 37 ºC (97 - 99 ºF):
- With 1 to 5 consecutive spins, wait 6 min between spins.
- With consecutive spins above 5, wait 9 min between spins.
Note: During use of QBC Malaria Test, room temperature should not exceed 37 ºC (99 ºF).
4.3 TUBE LOADING AND BALANCING
The top lid is spring-loaded and is automatically
released when the Power switch of the centrifuge
is off, provided the Power Pack is on and connected
to the centrifuge. When a spin cycle is completed,
the latch releases after a momentary delay and the
lid pops up (Figure 4-2).
Place tubes on the rotor in a balanced array,
with
the tube closures against the outer rim of the rotor. To
maintain balance, insert the tubes consecutively, starting at
slot #1.
When spinning an odd number of tubes (e.g., three),
BE SURE TO BALANCE THE ROTOR BY PLACING AN
UNFILLED QBC TUBE IN THE OPPOSITE SLOT
(e.g., #4 as shown in Figure 4-3). Use a closure and a float
in the balance tube.
