The Thermo Scientific Varioskan ALF Multimode Microplate Reader is a versatile, entry level reader for most common absorbance, turbidimetric, fluorescence, and luminescence microplate assays. Its photometric optical design is based on a xenon flash lamp and monochromator, enabling continuous wavelength selection from UV through visible range up to 1000 nm. The broad wavelength range enables many common assays, including nucleic acid and protein quantification, bacterial growth curves, ELISA, and cell viability.Thermo Science Varioskan ALF多模微孔板阅读器是一款通用的入门级阅读器，适用于最常见的吸光度、浊度、荧光和发光微孔板测定。其光度光学设计基于氙气闪光灯和单色仪，能够从紫外线到可见范围（高达1000 nm）进行连续波长选择。广泛的波长范围支持许多常见的测定，包括核酸和蛋白质定量、细菌生长曲线、ELISA和细胞活力。

Enhance your fluorescence and luminescence measurements with the filter-based optics使用基于滤光片的光学器件增强您的荧光和发光测量

With the Varioskan ALF reader, fluorescence and luminescence measurements are performed with filter-based optics for optimal specificity and sensitivity. The system comes with three pre-installed excitation and emission filter sets suitable for many common fluorometric applications like Quant-IT DNA quantitation assays and PrestoBlue and AlamarBlue cell viability assays. Additionally, five open filter positions are available for customized fluorometric and luminometric measurements. The filter slots are easy to access on the instrument's side with no tools required for filter exchange. Also, commonly used FRET and BRET assays are easy to set up and perform thanks to Varioskan ALF reader's unique filter-based optics design.借助Varioskan ALF阅读器，荧光和发光测量使用基于过滤器的光学器件进行，以获得最佳的特异性和灵敏度。该系统配有三个预装的激发和发射滤光片组，适用于许多常见的荧光测定应用，如Quant-IT DNA定量测定和PrestoBlue和AlamarBlue细胞活力测定。此外，五个开放的滤光片位置可用于定制荧光和发光测量。滤光片槽易于在仪器侧面访问，无需更换滤光片工具。此外，由于Varioskan ALF阅读器独特的基于过滤器的光学器件设计，常用的FRET和BRET测定易于设置和执行。
