Structural and functional characteristics：

1Jinan Xinbeixi Biotechnology Co., Ltd. is located in the pharmaceutical industry of the People's Republic of ChinaYY0569-2011《ⅡOne of the drafting units for the product standard of 'Biosafety Cabinet'；Its safety cabinet complies with industry standardsYY0569-2011《ⅡGrade Biosafety Cabinet ", also in compliance with national standardsRequirements of GB 41918-2022 "Biosafety Cabinets".

2. Cabinet bodyuse10 ° tilt angle design, in accordance with ergonomic principlesWith a larger perspective,operationConvenient and more convenienthommization;

3、The three side wall panels of the exposed work area of the safety cabinet are made ofhigh quality304#stainless steelIntegrated structure, internal washable parts adopt8mm rounded corner processing,No dead corners left, easy to clean;

4. The workspace is designed with negative pressure surrounding it on all four sides (left and right, rear, and bottom) for better protection and safety;

5The material of the workbench is of high quality304#Stainless steel, usingbasinshapeStyle design,Even if there is waste liquid overflowing from the experiment, it will not flow into the liquid accumulation tank, making it easy to clean;

* 6Fuma Wheel Wheel Design:The integrated design of casters and brackets allows the safety cabinet to move safely through the casters,It can also be fixed and leveled by adjusting the caster legs;

7、The cabinet and bracket can be separated,BracketThe height can be customized and modified according to the actual situation;

8Reasonable structural design:Maintenance of safety cabinet filters and fansReplacement can be carried out on the front side of the safety cabinet,Can be replaced by a single person,MorequickThe four cushion blocks at the bottom of the cabinet reserve space for lifting, making transportation safer and more convenient.

* 9The front window glass adopts double-layer laminated explosion-proof safety glass; Even if the glass is damaged, it will not harm people, and the biosafety cabinet can still work normally until the end of the experiment, which is even betterProtecting personnel andexperimentSafety;

* 10、LCDcolourLCD display screen, full parameter displayReal time dynamic display of the descending airflow velocity and inflow airflow velocity in the operation area,displayThe overall operating time of the safety cabinet,The operating time of the UV lamp, the temperature and humidity in the operating area, the resistance of the supply and exhaust filters, the display of the filter's usage time, and the barcode indicating the filterThe service lifeWhen all barcodes are illuminated, the filter's lifespan has expired,Display all operational statusIt is clear at a glance；

* 11、Foot pedal electricLightly tapFlexible control of glass door lifting and lowering through buttons, remote control, and electric powerDoor liftreachWhen operating at a safe height,automaticStop lifting and lowering to make the operation more convenient；And when the glass door is raised or loweredNo need to directly touch the glass, making the experimenters safer;

12Remote control: safety cabinetAll button operations can be achieved through remote control,sendThe use of safety cabinets is faster and more convenient; And the use of the remote control is greatly improvedReduced direct contact between users and the safety cabinet, providing greater protection for usersPersonal safety;

13Equipped with a scheduled appointment function, it can automatically set the safety cabinetTimed startup, shutdown, and UV lamp disinfection greatly save timeworktime，Improved work efficiency;

14、Strict airtightness testing: Safety cabinetInternal pressurization500Pa, maintain1After 0 minutes, the air pressure should not be lower than 450Pa.

15、Front window airflow partition design:Prevented itAirflow passes through the front window sidewallAnd leak from the upper side,sendtestMore secure;

16ExcellentofFan selection: When the safety cabinet is running normally without adjusting the speed control of the motor, the air pressure through the filter decreasesAt 50%, the exhaust volume of the fan decreases by no more than 10%

17ImproveThe alarm system:

（1) Glass doors are not safeHeight alarm: glass doorsecurityThe height is200mm， When the front side of the safety cabinet is higher or lower than the safety levelheightAt that time, the safety cabinet willSound and light alarm;

（2）FilterHigh pressure alarm: When the resistance of the filter increases,Safety cabinetWill sound and light an alarm

（3）Filter failurereplacecall the police：WhenAfter the lifespan of the filter expires, there will be a filterreplaceSound and light alarm;

（4）Airflow fluctuation alarmWhen:The airflow fluctuation of the safety cabinet exceedsNominal valueof20%WhenSound and light alarm,

18、Safe chain protection design: Chain protection is set up for all misoperations,even ifIncorrect operation will not cause harm

（1) Safety cabinetFan and glass door interlock：When the safety cabinet glassdoorWhen it reaches the bottom, the safety cabinet fan automatically shuts off,changeProtected itSafety cabinetThe use of the safety cabinet has increased its service life

（2）The UV lamp is interlocked with the glass door, fan, and lighting of the safety cabinet: the UV lamp can only be turned on when the glass falls to the bottom and the lighting is not turned on, to prevent accidental operation of the UV lamp from causing harm to the human body,More protectionThe safety of personnel；

*19Double trigger signal for closing the front window, enabling the UV lamp sterilization and disinfection function to be activated normally;

*20The negative pressure air duct is equipped with a foreign object filtering structure,preventPaper scrapsWaiting for foreign objects to enter the fan systemAffects the normal operation of the product;
