Fluorescence Cells and Cuvettes

Standard, Semi-Micro & Micro Fluorometer Cells w/ stopper

Type 23 cells are identical to Standard Rectangular fluorometer cells as listed on page 26 except that instead of having an open rectangular hole at the top, a block is fused to the top of the cell with a ground hole to receive a PTFE stopper. This provides a more suitable seal for volatile liquids. A PTFE stopper is supplied with each cell. Two stoppers are supplied with cells which have a path length of 40mm or greater.

Smaller volume Types 29F and 28F are identical to Types 9F Semi­Micro and Type 18F Micro cell ranges except they have a stopper instead of a lid. A PTFE stopper is supplied with each cell.

Fluorometer Micro Square Cells, adaptors

This range of Micro Fluorometer cells has been specifically designed by Starna for use with the FCA range of adaptors listed below. The adaptor locates the square cross section cell accurately in the center of the instrument cell compartment. Therefore, for a given path length, the cell is optimized for minimum volume and maximum sensitivity. All four windows and the base of the cells are polished and are available with either an open top or with a PTFE stopper sup­ plied with the type 23­ cells.

The FCA adaptors have exterior dimensions of a standard fluorometer cell (12.5mm x 12.5mm) and interior dimensions to accommodate the square micro fluorometer cells listed. Apertures are machined into the adaptor wall to allow for transmission of the excitation and emission energy at either 8.5 or 15mm 'Z' dimension. The aluminum adaptors are black anodized to eliminate stray light. The correct adaptor for a particular cell can be identified from the listing below.

Fluorometer Sub-Micro

Sub­Micro cells, Type 16F, while retaining the exterior dimensions of a standard cell, are designed for the measurement of very small samples with volumes ranging from 10μl to 160μl. The fluorometer Sub­Micro cells have a third window at 90° to the incident light to allow emis­sion energy to be measured. Special adaptors are not required for this cell.

Tandem or Divided Rectangular Fluorometer

Types 55, 56, 57 and 58 are all cells with two chambers which can be used either in parallel or series and with the exception of Type 55­1, have all walls polished. Types 57 and 58 have the facility for the intentional mixing of two liquids within the cell itself. PTFE stoppers supplied for type 56 and type 58 as pictured.

Fluorometer Flow Through

Type 583­F range of fluorometer flow cells is designed to fit most standard fluorometers. The inlet/outlet tubes are connected with a threaded M6 connector with PTFE tubing attached. A pair of M6 connectors is sup­ plied with the type 583 cell. The cells have three clear windows. The excitation beam passes through the cell, which also allows the cell to be used for absorption spectroscopy as well. The emission window is at 90 degrees to the excitation windows.

Fluorometer Flow Through, Type 46F, 47F, 71F & 72F

Fluorometer cells Type 46F and 47F (Semi­Micro) are for in­ line continuous flow type applications, usually measuring at one wavelength. Samples normally flow from the bottom to the top.

Types 71F and 72F (Semi­Micro) fluorescent cells have long windows and will fit normal cell holders. They can be used with instruments of any 'Z' dimension and are particularly suit­ able for any application where sample volume is not critical.

Fluoresence Reference Set

The 6BF reference materials are not standards with absolute values, but a set of six relatively stable fluorescent materials in a polymethyl-methacrylate matrix with which the stability of the instrument can be monitored. Four blocks exhibit broad band spectra which cover the normally used UV and visible region of the spectrum. Two blocks contain materials suitable for illustrating the selectivity of the technique as well as checking instrument resolution and wavelength calibration.

Standard, Semi-Micro & Micro Fluorometer Cells

Standard rectangular fluorometer cells Type 3 are the most popular cells for general fluorescence measurement and they will fit virtually every fluorometer instrument. All four windows and the bottom of the cell are polished and because of the technique used in their construction they remain extremely flat, right to the very edge of the window, allowing them to be used in some laser applica­tions. Each cell is supplied with a PTFE cover.

Smaller volume Types 9F, 17F & 18F are identical to the Type 9 Semi­Micro, Type 17 Short­Micro and Type 18 Micro range, except that all cell walls and the base are optically polished.

Fluorometer Cells Rectangular Micro with Screw Top

These fluorometer cells with the suffix GL14 are able to be used under anaerobic conditions. The cells with the GL14 suffix have a standard GL14 threaded top and cap which can be either a septum cap, GL14-S, or a plain closed cap, GL14-C.
