Mini CentrifugeApplicable fields
Palm shaped and mini sized centrifuges are domestically developed based on foreign products and are widely used in life sciences
As a low-speed and medium speed microcentrifuge field, precipitation or centrifugation for microtubes is necessary in routine life science experiments
A minimal prerequisite. This instrument is designed to reduce the frequency of use of high-speed centrifuges and can be used as an isotope centrifuge to reduce the use of high-speed centrifuges
The opportunity for pollution. The mini centrifuge also provides a 0.2ml 8-tube rotor for your gene amplification experiment.
Full mold injection molding, equipped with multiple centrifugal rotors, suitable for 15ml, 0.5ml, 0.2ml centrifuge tubes and 0.2ml PCR tubes
8 rows of centrifuge tubes, * replacing imported products, humanized switch design (turn when pressed, stop when opened), fully transparent arch shaped
The upper cover is equipped with multiple rotors, fully reflecting the new concept of "people-oriented, serving scientific research".
Mini CentrifugeWhat faults are encountered when using centrifuges in the laboratory, and how to eliminate these situations? Jiangsu Haimen Qilinbeier Instrument Manufacturing Co., Ltd. www.qilinbeier.. Com will take you to learn more details:
Mini CentrifugeDuring use, it is common for the motor to fail to start, such as when the main power indicator light is on. At this time, the degree of wear of the carbon brush should be checked. If the wear of the carbon brush exceeds one-third of the total amount, a new carbon brush should be replaced in a timely manner. When the main power indicator light is not on, check whether the fuse of the indicator light and the fuse of the indoor distribution board are blown. At the same time, check whether the power line is in good contact. If the fuse is broken, replace it and keep the circuit unobstructed. The vacuum pump gauge and oil pressure indicator should also be checked. If the oil pressure is too high and the main engine cannot be started, it is necessary to check whether each oil circuit is blocked, especially whether the throttle hole is unobstructed. If it is not unobstructed, it should be cleaned to make it unobstructed.
Bearing damage or restricted rotation, lack of oil or excessive dirt inside the bearing, resulting in increased frictional resistance, and the motor not reaching rated speed, should be cleaned or replaced in a timely manner. There is a layer of oxide on the surface of the commutator, which can cause unevenness or misalignment between the brush and the outer edge of the commutator. The commutator and brush should be cleaned to ensure good contact. If there is a short circuit or open circuit in the rotor coil, it can be checked with a multimeter and the coil can be rewound. During use, the rotor may cause centrifugal tube rupture, sample leakage, and rotor damage due to metal fatigue, overspeed, overstress, chemical corrosion, improper selection, unbalanced rotor during use, and temperature runaway. For the above situations, operators are mainly required to master the operating procedures proficiently, select suitable centrifuge tubes and rotors correctly, pay attention to strictly controlling each step of the operation sequence, minimize unnecessary human damage, and use the rotor within the safety factor and warranty period.
One of the reasons for the poor start-up and cooling effect of the freezer is that the power supply is not connected, and the power supply and fuse should be checked separately. Low voltage and safety device failure can also prevent the freezer from starting. Low voltage may be due to low grid voltage; Excessive wiring on the distribution board; The power cord is too long (ideal length is 3 meters), etc. The insufficient capacity of the power cord not only reduces the voltage, but also causes accidents.
