MODEL ZF-90 ULTRAVIOLET TRANSMISSION INSTRUMENT WITH MULTI ELNCTIONS AND DARK BOX-LIKE
　　此仪器上面安装了254nm和365nm的紫外光源，透射紫外光源采用302nm紫外光源灯管采用紧密排列，仪器可配摄影装置。对DNA和RNA的条带进行观察和拍摄时，因采用各种波长紫外光，所以其清晰度可接近国外同类仪器的水平，并排除可在照相底片上出现灯管阴影的现象。是我厂参照了国外同类仪器的优点，在征集了广大用户建议后精心设计制造了这台确有多种用途和多种功能的实验分析仪器。
ZF-90用途：
　　可广泛适用于遗传工程、分子遗传学、微生物学、 生物制品畜牧医学卫生、药品药物的研究和检定。还可适用于卫生防疫部门，食品行业、纺织、石油橡胶、 探矿行业，考古文物鉴定，痕检、jia票的检定，适用于凡是需要进行荧光分析和检定的部门。是从事 现代科学研究部门，检验监督部门的常用仪器。

There are two ultraviolet sources with the wavelength of 254 nm and 365 nm which are installed respectively on both sides of this instrument and one set of visible light source which is installed on the one side. A ultraviolet source with middle wavelength of 302 nm is adopted as a transmission source. The light tubes are arranged tightly. A camera can be allocated in the instrument if need. When applying this instrument to observe or photo the bands of DNA and RNA, the distictness can be compared with that of same type instrument produced abroad and the shadow of the light tubes which is always appeared on the photo film will be wliminated because the ultraviolet light with various wavelength is applied in this instrument. After referring to the advantages of the same type instrument produced abroad and to the various proposals suggested from the users, this instrument for the experimental and analysis purpose with muLti- functions and multi-users was finely designed and manufactured.
