CAUTION:

Use serum samples that are completely separated from blood clots or urine samples that are free from suspended matter. If fibrin exists in the serum samples or suspended matter exists in the urine samples, the probe may be blocked.

Medicines, anticoagulants or preservative in the samples may lead to unreliable results.

Hemolysis, jaundice or chylomicron in the samples may lead to unreliable test results, so sample blanks are recommended.

Store the samples properly. Improper storage may change the compositions of the samples and lead to unreliable results.

Sample volatilization may lead to unreliable results. Do not leave the sample open for a long period.

Not all the tests the reagents claim capable of analyzing can be analyzed on the system. Consult the reagent suppliers for details.

Certain samples need to be processed before being analyzed by the system. Consult the reagent suppliers for details.

The system has a specific requirement on the sample volume. Refer to this manual for proper sample volume.

Load the sample to proper tube position on the sample disk before the analysis begins; otherwise you will not obtain correct results.

1.1.1.1 Sample/Reagent Disk

The sample/reagent disk holds sample tubes and reagent bottles.

Figure 1-2 Sample/Reagent disk

Sample/reagent Disk

The disk is composed of two circles – sample disk on the outer circle and reagent disk on the inner circle.

1-2

System Description

The sample disk provides 40 sample tube positions and the reagent disk provides 40 reagent bottle positions. On the reagent disk, No. 39 is for detergent and No. 40 is for distilled water.

NOTE

Mindray recommends you to use the following detergents:

Acid: 0.1mol/l hydrochloric acid; Alkaline: 0.5% (V/V) javel water

The sample disk can hold the following sample tubes:

Micro sample cup and centrifugal tube

Collection tube: Ф12×68.5, Ф12×99, Ф12.7×75 and Ф12.7×100

Plastic tube

The reagent disk can only hold Mindray bottles, which are available in two types, 40ml and 20ml.

The sample/reagent disk is located in the sample/reagent compartment, which has a refrigerator to keep the temperature at 4-15 ˚C.

WARNING:

Make sure the disk cover is closed; otherwise it may degrade the refrigeration and damage the probe.

Before running the analyzing unit, make sure that the disk cover is closed and the round red mark on the cover is aligned with its counterpart on the panel. Otherwise the probe may be damaged.

NOTE

The refrigerator will be put into service once the MAIN POWER is turned on.

Do not use sample tubes and reagent bottles other than the specified ones.

1.1.1.2 Dispenser

The dispenser is composed of a probe, arm and rotor.

1-3

System Description

Figure 1-3 Dispenser

Arm

	Rotor
Probe	Wash Well

The probe aspirates certain amount of sample from the designated sample tube, or reagent from the designated reagent bottle, and then dispenses them into the designated cuvette on the reaction disk.

After dispensing the sample or the reagent, the probe moves to the wash well for cleaning.

Sample volume: 3µl-45µl; precision: 0.5µl.

Reagent volume: 30µl -450µl; precision: 1µl.

The dispenser is capable of preheating the reagent, detecting the sample/reagent level, capable of tracking level and protecting against collision in the vertical direction.

WARNING:

When the analyzing unit is in operation, do not place any part of your body or any obstacle in the route the arm moves. Otherwise, it may lead to personnel injury or equipment damage.
