 An experimental station layout

In natural light where there should not be parallel to the exterior lighting window , because when people are facing window glare, but back when , countertops produce shadows.

 A. Set Island Central bench should consider the processing pipeline , several cases are listed below :

( A ) stamped on the floor digging trench plate , there is a leak , effusion , but ease of maintenance ;

( 2 ) Floor buried , when problems arise , you need to open up the repair and replacement , affecting around ;

( 3 ) there is leakage problem wearing floor , downstairs high-precision instruments should not be set too high maintenance inconvenience ;

( 4 ) suspended , too ugly , affect the appearance. 

B. Recommendations set peninsula central station ( Island lab bench ) , the advantage is easy to buried pipelines .

( 4 ) two-sided table that Island bench : 1500mm

 Three experimental stations combined

( A ) laboratory bench tops as far as possible the whole piece countertops, standard cabinet portfolio to reduce countertops patchwork ensure bench overall appearance, convenient debugging and improve the construction schedule .

( 2 ) extensor notch width : 600 ~ 1100mm

( 3 ) Reagent rack : Two bottles of medium depth can be juxtaposed reagent bottle (500ml) is appropriate. Usually 200 ~ 300mm, upper and lower layers ;

( 4 ) by the wall abutment with the reagent rack to take : 200mm

( 5 ) to take central stage with reagent rack : 300mm

 Four for special laboratory planning requirements 

( A ) Spectrum Room :

 Water supply: water pressure of not less than 2Kg/Cm2.

 Power supply: single-phase three-wire required 110VAC, 220VAC and 380VAC three-phase five-wire power .

( 3 ) Optical diffraction analysis instrument rooms :

 With sample treatments : There are sinks , bench , fume hoods , etc. ;

 Instrument room : room temperature 20 ± 5 ℃, humidity of 65 ± 5%; thickness sufficient protection , protective door signaling device must be turned off , to have good ventilation , need to have : a vacuum , compressed air, cooling water supply .

( 4 ) chromatographic analysis room :

 With cylinders Storage :

 Instrument room : room temperature 20 ± 5 ℃, humidity of 65 ± 5%; chromatography instruments have a solid platform , the instrument sets the distance from the wall should be 600mm, in order to repair the instrument , the instrument should have local exhaust hood above the device .

( 5 ) Atomic Absorption Room :

 With sample treatments : There are sinks , bench , medicine cabinets , fume hoods , etc. ;

 Easy and liquid chromatography , gas chromatography in the same room.

 Temperature 22 ~ 27 ℃, humidity 65 ± 5%; have a solid platform chromatography instruments , apparatus, Taiwan should the distance from the wall 600mm, in order to repair the instrument .

 Gas : gas lines generally have three kinds : nitrous oxide , acetylene gas , compressed air, gas cylinder storage room into the interior route , total indoor pipeline through the regulator valve points to each chromatograph, connecting each chromatogram Miriam front of the needle valve . Air compressor pump gas available to help .

 Ventilation: atomic absorption with combustible gases, carbon dioxide released by burning , have good indoor ventilation, local exhaust instrument should cover the top of the device .

 Power supply: single-phase three-wire required 110VAC, 220VAC and 380VAC three-phase five-wire power .

( 7 ) Liquid Chromatography room :

 With sample treatments : There are sinks , bench , medicine cabinets , fume hoods , etc. ;

 Easy and atomic absorption , gas chromatography in the same room.

 Temperature 22 ~ 27 ℃, humidity 65 ± 5%; have a solid platform chromatography instruments , apparatus, Taiwan should the distance from the wall 600mm, in order to repair the instrument .

 Ventilation: liquid chromatography with organic gases , have good indoor ventilation , the top of the instrument have local exhaust hood devices.

 Power supply: single-phase three-wire required 110VAC, 220VAC and 380VAC three-phase five-wire power .

( 8 ) Gas chromatography Room :

 With sample treatments : There are sinks , bench , medicine cabinets , fume hoods , etc. ; easy and liquid chromatography , gas chromatography in the same room. Temperature 22 ~ 27 ℃, humidity 65 ± 5%; have a solid platform chromatography instruments , apparatus, Taiwan should the distance from the wall 600mm, in order to repair the instrument .

Gas : gas lines are generally equipped with four kinds : nitrogen, hydrogen , helium , compressed air, gas cylinder storage room into the interior route , the road to increase the gas filter into the interior through the total pipeline regulator valve points to each a chromatograph , connecting each chromatograph front needle valve . Gas can be used to help air compressor pump , hydrogen hydrogen generator available . TCD detector exhaust pipe connected to the outdoor use .

Ventilation: chromatographic chamber with hydrogen and carbon dioxide released by burning , have good indoor ventilation.

Power supply: single-phase three-wire required 110VAC, 220VAC and 380VAC three-phase five-wire power .

( 9 ) balance room :

Balance is an essential common chemical laboratory equipment.

Precision scales have certain requirements on the environment : vibration , dust, direct sunlight , corrosive gases and has a constant temperature of erosion , it set up special balance room to meet the above requirements .

North to the appropriate balance room , but also away from the vibration source , not with the high temperature chamber and strong electromagnetic interference adjacent room . The high-precision microbalance should be located on the ground floor .

To balance room with double windows, insulation dust conducive to the balance chamber is preferably provided with a transition between the entry to be protected from the impact of airflow , air conditioning , wind speed should be small .

Scale indoor basin or may not set any pipe through indoor , avoid leaking pipes , condensation or in the pipeline overhaul of the use and maintenance of the balance .

Try not to put unnecessary furniture to reduce dust.

Other environmental factors that impact on the balance : people walking, door switches.

Low environmental impact on the largest scales .

The installation can not be close to the wall , from the wall to be 20mm ~ 50mm, to prevent from the vibration .

  Five laboratory ventilation piping planning and measurement requirements

Draw a line chart

Customers planning and design in the same ventilation system , be sure to get the engineering related field measurement data , laboratory equipment Co., Ltd. Shanghai Yu Shan under the general planning scheme , summed up the general planning steps required : Laboratory plane size of the room , which floors, floor headroom height of the room and the floor beams , ceiling and floor height , ventilation products in the size of the room layout position , the position of the wall the size of the windows , the roof in which the floor , fans sited on rooftops size , customer requirements towards the exhaust pipe , exhaust well -sectional size.
