产品说明书



超净工作台的优点是操作方便自如 ,比较舒适,工作效率高,预备时间短,开机


30


< p>
钟以上即可操作,基本上可随时使用。在工厂化生产中,


接种工作量很大,


需要经常长久地


工作时,


超净台是很理 想的设备。


超净工作台由三相电机作鼓风动力,


功率

< p>
145



260W


左右,


将空气通过由特制的微孔泡沫塑料片层叠合组成的“超级滤清器”后吹送出来,


形成连续不


断的无尘无菌的超净空气层流,


即所 谓“高效的特殊空气”,


它除去了大于


0.3

< br>μ


m


的尘埃、


真菌和细菌孢子等 等。超净空气的流速为


24



30m/ min


,这已足够防止附近空气可能袭扰而


引起的污染,


这样的流速也不会妨碍采用酒精灯或本生灯对器械等的灼烧消毒。


工作 人员就


在这样的无菌条件下操作,


保持无菌材料在转移接种过程 中不受污染。


但是万一操作中途遇


到停电,

暴露在未过滤空气中的材料便难以幸免污染。


这时应迅速结束工作,


并在瓶上作出


记号,


内中的材料如处于增殖阶段,


则以后不再用作增殖而转入生根培养。


如为一般性生产


材料,因极其丰富也可弃去。如处于生根过程,则可留待以后种植用。


< /p>


超净台电源多采用三相四线制,


其中有一零线,连通机器外壳,应 接牢在地线上,


另外三线


都是相线,工作电压是


380V


。三线接入电路中有一定的顺序,如线头接错了,风机会反转,


这时声音正常或稍不正常,


超净台正面无风


(


可用酒精灯火焰观察动静,


不宜久试


)



应及时


切断电源,

< br>只要将其中任何两相的线头交换一下位置再接上,


就可解决。

三相线如只接入两


相,或三相中有一相接触不良,


则机器声 音很不正常,应立即切断电源仔细检修,


否则会烧


毁电机。


这些常识应在开始使用超净台时就向工作人员讲解清楚,


免除不应造 成的事故与损


失。



超净工作台进风口 在背面或正面的下方,


金属网罩内有一普通泡沫塑料片或无纺布,


用以阻


拦大颗粒尘埃,应常检查、拆洗,如发现泡沫塑料老化,要及时更换。除进风口 以外,如有


漏气孔隙,应当堵严,如贴胶布,塞棉花,贴胶水纸等。工作台正面的金属网 罩内是超级滤


清器,超级滤清器也可更换,如因使用年久,尘粒堵塞,风速减小,不能保 证无菌操作时,


则可换上新的。



超净 台使用寿命的长短与空气的洁净程度有关。


在温带地区超净台可在一般实验室使用,



而在热带或亚热带地区,


由于大气中含有 高量的花粉,


或多粉尘的地区,


超净台则宜放在较


好的有双道门的室内使用。


任何情况下不应将超净台的进风罩对着开敞的门或 窗,


以免影响


滤清器的使用寿命。


< /p>


无菌室应定期用


70%


酒精或

< p>
0.5%


苯酚喷雾降尘和消毒,用


2%

< p>
新洁尔灭抹拭台面和用具


(70%


酒精也可


)


,用福尔马林


(40%

甲醛


)


加少量高锰酸钾定期密闭熏蒸,配合紫外线灭菌灯< /p>


(


每次


开启


15


分钟以上


)


等等消毒灭菌手段,


以使无菌室经常保持高度的无菌状态。


接种箱内部也

< br>应装有紫外线灯,使用前开灯


15


分钟以上照射灭菌,但 凡是照射不到之处仍是有菌的。在


紫外线灯开启时间较长时,


可 激发空气中的氧分子缔合成臭氧分子,


这种气体成分有很强的


杀 菌作用,


可以对紫外线没有直接照到的角落产生灭菌效果。


由于 臭氧有碍健康,


在进入操


作之前应先关掉紫外线灯,关后十多分 钟即可入内




在超净工作台上亦可吊装紫外线灯,


但应装在照明灯罩之外,


并错开照明灯平行排列,


这样


在工作时不妨碍照明。


若将紫外线灯装入照明灯罩


(


玻璃板

< p>
)


里面,


这是毫无用处的,


因为紫


外线不能穿透玻璃,它的灯管是石英玻璃,而不是硅酸盐玻璃制成的。
