Starna

Starna Spectrophotometer Cells Spectrophotometer cells are used for holding your samples to be measured for absorbance or transmission in all common spectrophotometers.
There is an accepted international standard for the size, shape and materials for the construction of these cells. Starna spectrophotometer cells comply with these standards so that our cells can be used with most spectrophotometers made anywhere in the world.

We make a large selection of cells so that you can select the best design of cell for your sample type, size and wavelength range.

Validate your instruments with
Starna UV/Vis and Fluoresence Certified Reference Sets Use these reference sets to easily validate your UV/Vis and fluoresence spectrophotometers. Each set is supplied with a certificate of analysis and NIST Traceability from our ISO 17025 and UKAS accrediated reference laboratory.

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.

Sub-Micro Spectrophotometer Cells

Sub-Micro cells, Type 16, 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 entrance to the sample compartment is hemispherical, being designed without sharp corners to eliminate potential loss of sample by capillary action. The amount of sample required to fill the sample chamber is reduced to an absolute minimum, typically fifteen to twenty per cent greater than the absolute sample chamber volume. The sample is easily inserted into and retrieved from the cell by careful use of a pipette or syringe.

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 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.

Low Head Space Sub-Micro Cells

Low head space Sub-Micro cells are designed for thermal melt. The low head space cells hold volumes ranging from 10µl to 160µl while retaining standard exterior dimensions. The entrance to the sample compartment is hemispherical, being designed without sharp corners to eliminate potential loss of sample due to capillary action. Cells are supplied with a special PTFE stopper. The liquid tight stopper reduces the volume of air.

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.

Triangular, Dual-Path Length Fluorometer

Triangular fluorometer cells Type 4, with open top or Type 24 with PTFE stopper, are useful for front surface fluorescence measurement. This technique is employed when the sample is too dense for the transmission of excitation or emission energy. Analysis is made by exciting the face of the sample at an angle of 45° to both the excitation source and the emission detector.

Dual path length cells Types 52 and 53 allow for both fluorescence and absorbance measurements to be made with small volumes with a choice of two path lengths, dependent on the orientation of the cell in the cell holder. All cells have a 10mm path length in one direction and a smaller path length at 90°. All four windows and the base are clear. Type 53 is supplied with a PTFE stopper.Full Detail

Closed & Septum Screw Cap Cells

Cell types with suffix ST are able to be used under anaerobic conditions. Cells designated with small ST cap have threaded top and cap which can be either a septum cap, ST-S or a plain closed cap, ST-C. Each cap contains a silicon seal to give you an air tight fit. The ST caps (12mm diameter) do not extend beyond the perimeter of the cell.

Magnetic Stirrer

The Spinette cell stirrer is a simple solution to mixing solutions inside of a spec­ trophotometer or fluorometer cell. The spinette drives a small electronic magnetic stirrer which has the same exterior dimension as a normal cell and is only 5mm thick. It is placed into the bottom of the cell compartment, the cell is then placed on top of the magnet drive. A ribbon connector is brought up the non­transmitting side of the cell and then connected into the spinette controller. A standard cell is fully mixed within 4 seconds. The spinette works well with any standard cell with a 10mm x 10mm interior or with any of the special stirring cells as listed above. Each spinette comes complete with one stir bar, electronic magnet driver, ribbon cable and 120V AC controller.
