DLR Ready! An Overview

The Turner Designs TD-20/20 is the ideal research luminometer, offering exceptional sensitivity and versatility. It can measure light output using test tubes, culture dishes, and scintillation vials, as well as beads, strips, and other solids. The wide dynamic range enables the user to run assays requiring ultimate sensitivity as well as assays with high light output.

For years the Turner Designs Model 20e Luminometer was used throughout the world in research, academic, and environmental applications. Known for its extreme sensitivity and rugged "workhorse" design, the Model 20e served its customers well by providing reliable, reproducible results day-after-day, year-after-year.

Turner Designs carries on the Model 20e tradition with the TD-20/20 Luminometer. Designed to match the 20e's sensitivity, it also offers an up-to-date style and the versatility required to meet the needs of cutting-edge researchers in the field of luminescence.

Features of the TD-20/20

NEW!Spreadsheet Interface for the TD-20/20Spreadsheet Interface Software

Turner Designs now includes Spreadsheet Interface Software with every TD-20/20 Luminometer. This software allows the user to directly capture data from the luminometer to an Excel spreadsheet. This feature saves time by eliminating the middle step of transferring data from an ASCII file to an Excel file, as well as removes the possibility of transcription errors.

Features of the Spreadsheet Interface Software:

  • Provides easier data handling.
  • Saves time.
  • Removes possibility of transcription errors.
  • Offers simple one time set-up.

NEW!Blanking Capabilities

Reagents often have an intrinsic background luminescence that contributes to the luminescence readings of standards and samples. Researchers need to manually subtract this background to obtain accurate readings. The Turner Designs TD-20/20 Luminometer now includes the ability to automatically subtract the average of up to 5 blank readings offering increased accuracy as well as simplicity.

Features of the Blanking Capability

  • Increased accuracy in standard and sample measurements.
  • Up to 5 blanks may be averaged for greater accuracy.
  • Instrument stores separate blank values for each mode of operation: standard versus DLR.
  • Easy-to-use menu-driven software.
  • Blanking capability may be turned off if not desired.
