MODEL ZF-90 ULTRAVIOLET TRANSMISSION INSTRUMENT WITH MULTI ELNCTIONS AND DARK BOX-LIKE
　　此儀器上面安裝了254nm和365nm的紫外光源，透射紫外光源采用302nm紫外光源燈管采用緊密排列，儀器可配攝影裝置。對DNA和RNA的條帶進行觀察和拍攝時，因采用各種波長紫外光，所以其清晰度可接近國外同類儀器的水平，并排除可在照相底片上出現(xiàn)燈管陰影的現(xiàn)象。是我廠參照了國外同類儀器的優(yōu)點，在征集了廣大用戶建議后精心設計制造了這臺確有多種用途和多種功能的實驗分析儀器。
ZF-90用途：
　　可廣泛適用于遺傳工程、分子遺傳學、微生物學、 生物制品畜牧醫(yī)學衛(wèi)生、藥品藥物的研究和檢定。還可適用于衛(wèi)生防疫部門，食品行業(yè)、紡織、石油橡膠、 探礦行業(yè)，考古文物鑒定，痕檢、jia票的檢定，適用于凡是需要進行熒光分析和檢定的部門。是從事 現(xiàn)代科學研究部門，檢驗監(jiān)督部門的常用儀器。

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.
