   The Lab-Tec Jr. is a programmable spectrophotometer designed for reliable, low volume analysis.


Linear Measurement Range:

0.00 to 2.50 Absorbance units (A)

Photometric Accuracy:

+ / - (1% of the reading + 0.005 A)
Stability: drift of no more than 0.005A in 8 hours
Light Source: Tungsten Halogen
Standard Wavelengths: 340, 405, 450, 492, 545, 600nm
Type of filter: 3 cavity sealed interference, 10nm half band pass
Tube Size: Std is 12mm round
Min. fill volume accessory: 1ml for 12mm tube, 250uL with aspirator
