How to use and care of laboratory centrifuge

Learn more about laboratory centrifuges information please pay attention to http://www.shlxj.com.cn/.

When using the laboratory centrifuge, component can not exceed the laboratory centrifuge materials acceptable component, the material shall be uniformly placed in the exact center, so that it is not due to overweight and cut the centrifuge using life. Of course we also need timing on laboratory centrifuge refueling maintenance, generally every 6 months. The need to look at within the centrifuge device can appear wear and loosening, wear serious hypothesis, in a timely manner to convert.
Centrifuge is a common thing in the laboratory, the first used respectively in the colloidal solution of solid phase and liquid phase. Using the method of high speed spiral makes each particle centrifugal tube to get an acceleration, and according to the solid density of more than liquid, and then the solid-liquid respectively. Use a lot of centrifuge in chemical, petroleum, pharmaceutical, food, mineral processing, coal, water treatment and some ships etc.. Laboratory centrifuge work is operating at a high speed, to pay attention to safety when used, laboratory centrifuge for use and maintenance of general centrifuge we briefly introduced under the.
1, when the centrifuge use to be placed in the stable, the consolidation of the table. The centrifuge base are equipped with a rubber suction foot, laboratory centrifuge with the help of the atmospheric pressure and the instrument itself weight, close to the table. Large capacity low speed centrifuge and high-speed refrigerated centrifuge accordingly in solid ground, horizontal; ultracentrifuge weighing hundreds of kilograms, should be placed in a very solid ground and a dustproof, dampproof equipment, to ensure that the centrifugal chamber arrives at certain vacuum degree, the normal work.
2, the centrifuge must adhere to the safety interval near 750px above, and shall not store any dangerous goods in a centrifuge nearby.
3, select the appropriate control back to back, speed, speed setting may not exceed the maximum speed.
The maximum speed of laboratory centrifuge in the condition to fall back:
A) back to work time and work rules of life when the number of arrival;
B) back by some surface damage or the pipe hole slender corrosion;
C stainless steel centrifugal pipe, casing) use, thick wall pipe or centrifugal bottle;
The D sample with uniform density) over 1.2g/cm3; back by high temperature.
Back in 4, before each use to a foreign body and dirt can serious view hole, to maintain balance.
A) back must adhere to monotone cleaning, do not bump scratch. Such as accidentally fell back, deal with suspension of X
Optical film viewing, admit no internal damage in front of sustainable use;
B) back to use warm water after each use (50 DEG -60 DEG) and neutral detergent soak cleaning, finally with distilled water or deionized water wash, dry with a soft cloth after use hair dryer drying, waxing, monotone custody.
5, all kinds of centrifugal pipe tensile strength and elongation are not the same, should be adopted as required.
A) centrifuge tube can be made of many different materials, such as polyethylene, polypropylene, polycarbonate, such as cellulose. The use of pay attention to ensure that the sample, solvent and gradient material is not corrosion and cover assembly centrifugal tube;
B) expired, aging, cracked or corroded centrifuge tube as far as possible without or slow down the use of;
C control) using plastic centrifuge tube number, pay attention to supporting standard.
6, centrifugal pipes to be symmetrically placed, and must equal perfusion samples. Take heed of centrifugal pipe should be installed 7 to full,
Although with the lid, but can also be due to the centripetal force is too strong and leakage. Laboratory centrifuge know that most of the centrifugal tube is accompanied by the lid, the lid carefully centrifugal tube will together equilibrium, do not cut in the back to work in the case of unbalanced.
7, centrifuge a work is best not more than 60 minutes.
In 8, the centrifugal process such as the discovery of abnormal phenomena, such as abnormal noise and vibration, should immediately press the STOP (and non power off POWER) stop viewing, not find reasons shall not continue to work before.
The machine faults occurring in the use of instruments in the process, the damage of the components of the situation should be promptly and technical personnel contact.
9, in the process of centrifuge work, don't open the centrifugal chamber cover, shall not be used for knocking hand or foreign body is back and centrifugal rotation in the tube, and don't bump or mobile centrifuge, or rely on, sit on the centrifuge.
10, centrifugal, to centrifuge intact after the stop, open the hatch to hurry out of talent, centrifugal tube. The first observation of centrifugal pipe can intact sedimentary and sedimentary range.
No matter what to is the upper or deposition, please take a clean beaker to collect the supernatant, avoid error. Be careful to avoid dumping supernatant, the deposition together poured out; if not be mixed together, will come again. If the centrifugal pipe leakage, to find out the reasons, and quickly clearing centrifugal cavity or centrifugal lab centrifuge.
11, the use of laboratory centrifuge machines is completed, laboratory centrifuge advice should do the cleaning work, cleaning stick machine.
