MicroReader 3 Accessories & Options

Single Well Adapter (#2027-125): Allows individual wells, from 1 to 8, to be run using BREAK-AWAY microwell strips.

NUNC Microwell Strip Adapter (#2027-126): Allows the use of this type of microwell strip with the MicroReader 3.

MicroReader 3 Test Fixture Set (#2027-128): Allows one to confirm the MicroReader 3 is operating within its specifications.

Coagulation Software: Measures the delta-absorbance between a given substance and a standard well and converts the delta-absorbance value to concentration using a preprogrammed curve.

Delta-Absorbance (Non-Kinetic) Software: MicroReader 3 groups a standard and a sample into a pair so that the absorbance readings can be subtracted in order to determine the "difference" between them.

Auto-Logit Test Software: Similar to a Concentration Curve Test, its X-Axis is based concentration. However, the Y-Axis is always based on Logit of absorbance, rather than "absorbance only".
