DEN-600 isa compact, portable, rechargeable battery powered photometer.
DEN-600comprises of600 nm wavelength optical system, which enables to apply
1) OD600 method thatestimated total number of cells,
2)McFarland (McF) turbidity measurement method,
3) Bradford protein assay method for protein concentration measurement
The deviceservesasan inexpensivealternativeto a spectrophotometer, which is commonly used for these applications.
Because DEN-600is battery powered and compact, it can becomfortably located in a biosafety cabinet,anaerobic chamber or quickly moved to another lab room.
Additionally, thevessel holding mechanism allowsaccommodating standard 10 mm path cuvettes, round bottom, conical vials or falcon tubes, thereforeenabling to measuretheabsorbanceand turbidity in Abs, OD or McF units.
USB connectivity and DEN softwareallow for data transfer, data processingand calculation, software calibration for Bradford protein assay method ora custom calibration fora specifically applicablevesseland custom turbidity standards.

Cuvette
不限材質
標準比色管高度
只要是口徑1CM即可
Cuvette 分內凹型、全平面兩種
若為內凹型要注入 1cc
若為全平面要注入 2cc
一般16/18mm管子可使用，只要是透明的counting tube都可讀，但尺寸要16/18mm(口徑)
