An Overview

The TD-700 Laboratory Fluorometer is a compact, low-cost benchtop fluorometer that features a unique multi-assay filter cylinder, wide wavelength range, menu-driven software, and multi-point calibration. A variety of compounds can be easily measured using application-specific optical filters available from Turner Designs.


Features of the TD-700
  • Multi-Assay Filter Cylinder houses eight easily-changeable filters for four different applications.
  • Wide wavelength range: measures flourescence from UV to red range
  • Automatic Range Optimization: range, gain, and resolution are set automatically - eliminates operator error from working in the wrong range.
  • Multi-point calibration: stores a 1-to-5 point calibration curve for quantitative determinations.
  • Kinetics Software: outputs data to a computer or printer at selectable intervals.
  • Versatile Sample Compartment accommodates 25 x 150 mm round, 13 x 100 mm round, 10 x 10 mm square cuvettes, 100 Ál minicell, or 9 Ál microcell.
  • Menu-Driven Software guides the user through calibration and analysis.
  • RS-232 for serial data output to a printer or computer.


The Unique Filter Cylinder

The Unique Filter Cylinder
  1. Lift the TD-700's sample chamber door and the unique filter cylinder slips out easily; it is ported to allow four different filter combinations.
  2. Eight one-inch round filters (four excitation and four emission) are easily inserted.
  3. Seat the filter cylinder back in its chamber. With eight filters installed, the user can now switch between four different fluorescence analyses in seconds, just by rotating the cylinder.


The Minicell Adapter Kit

The Minicell Adapter Kit and TD-700 Laboratory Fluorometer combine to form a convenient, versatile, and reproducible measurement system using 75-250Ál.


The Helix Microcell

For applications where small volumes are a concern, The Helix Microcell allows the user to work with 3 to 9Ál of assay solution.
