Horizontal flow ultra-clean bench details:
Principle is in a specific space, the indoor air through the pre-filter primary filtration, by small centrifugal fan pressed into the static pressure box, and then through the air high-efficiency filters secondary filtration, from the air high-efficiency filters out of the surface of the clean air flow with a certain and uniform cross-section of the air speed, you can exclude the work area of the original air, dust particles and biological particles away to form a sterile and highly clean working environment ultra. particles away to form a sterile and highly clean working environment.
How to use the clean bench
The advantages of the ultra-clean bench is easy to operate freely, more comfortable, work efficiency , short preparation time, more than 10 minutes after the start-up can be operated, basically can be used at any time. In factory production, inoculation workload is very large, need to
Frequently work for a long time, the ultra-clean table is very ideal equipment. Ultra-clean table by the three-phase motor for the wind power, the rate of 145 ~ 260W or so, will be the air through the special microporous foam sheet layer stacked group
"Super Filter" after blowing out, the shape of a continuous dust-free and sterile ultra-clean air laminar flow, that is, the so-called "effective special air", it removes the dust and germ-free air, which is the most effective air, the most effective air, the most effective air. Ultra-clean air flow rate of 24 to 30m/min, which is sufficient to prevent contamination caused by the possible attack of nearby air, such a flow rate will not prevent the use of alcohol lamps or Bunsen burns on instruments and other disinfection. The staff operates under such aseptic conditions to keep the sterile material free from contamination during the transfer of inoculation
. However, in the event of a power failure in the middle of an operation, it is difficult to avoid contamination of materials exposed to unfiltered air. In this case, the work should be quickly terminated and the bottles should be marked, and if the material inside is in the
proliferative stage, it should not be used for proliferation in the future, but should be transferred to rooting culture. If it is a general production material, it can be discarded even if it is very abundant. If it is in the rooting stage, it can be saved for later planting.
The ultra-clean table power supply more than three-phase four-wire
, which has a zero line, connected to the machine shell, should be firmly connected to the ground, the other three lines are phase, the working voltage is 220 V. Three lines into the circuit in a certain order, such as the wrong end of the line, the wind machine will be reversed, the sound of the normal or slightly abnormal, the ultra-clean table front wind (available alcohol lamp flame to observe the movement, it should not be Long test), should promptly cut off the power supply, only any two-phase wire exchange position and then connected, can be resolved. Three-phase line, such as only access to two-phase, or three-phase has a poor contact, the machine sounds very abnormal, should immediately cut off the power supply to carefully overhaul, otherwise it will burn the motor. These common sense should be in the beginning of the use of ultra-clean table on the staff to explain clearly, to avoid should not cause accidents and losses.
Super-clean air inlet in the back or front of the lower part of the metal mesh cover has an ordinary foam sheet or non-woven fabric, to block large particles of dust, should always check, dismantle, such as hair foam aging,
Timely replacement, general primary filter 3 weeks -2 months to replace one, in addition to the air inlet, if there is leakage of air porosity, it should be blocked, such as tape, stuffed with cotton, stick glue paper, etc. The metal mesh cover on the front of the working table is a super filter, the super filter can also be replaced, such as
used for a long time, dust particles clogging, wind speed decreases, can not guarantee the aseptic operation, it can be replaced with a new one. High-efficiency non-septum filter is generally changed once in 1-2 years,
