Spectrometer Cells and Cuvettes

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.

Micro Cells Short and Ultra-Micro Cells

Type 17 Micro cells are similar to Type 18 Micro cells except that the external height is only 25mm. Because of their reduced height, it is essential that the correct micro cell holder is used for the instrument, otherwise it will be difficult to remove the cells from the cell holder. Both black wall self masking cells and clear wall cells are available in this range. Each cell has an open top and is supplied with a PTFE cover.

The configuration of the small sample compartment in the Type 19 Ultra-Micro cell range optimizes the alignment of the sample for maximum sensitivity in the spectrophotometer. The sample is easily inserted into and retrieved from the cell by careful use of a pipette or syringe.

Semi-Micro Self-Masking Black-Wall Cuvettes

The purpose of Semi-Micro Type 9 cells is to reduce the sample volume necessary to make a measurement. The volume of a Semi-Micro cell is approximately 40% of an equivalent path length standard rectangular cell. 9B cells have non transmitting self masking black walls which improve sensitivity by eliminating stray light from measurements. The interior sample compartment width of Semi-Micro 
cells is reduced to 4mm, therefore it is essential to determine that the light beam from the instrument passes centrally through the sample compartment.

Clear & Self-Masking Micro Cells w/ Stopper

Type 28 cells are identical to Type 18 Micro cells, except these cells are supplied with a PTFE stopper, or stoppers as pictured, to fit in a ground cone to reduce evaporation of volatile samples. The external height is 48mm plus the stopper. Micro cells are available with either clear walls which will transmit energy or opaque black walls for improved sensitivity. Alignment of Micro cells in instrument cell holders is critical.

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

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.

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.

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

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.

Constant Temperature Cells

Constant temperature cell Types 62, 63 and 65 are designed with a separate chamber surrounding the sample compartment through which a temperature controlling fluid can be circulated to keep the sample at a specific temperature. Type 62 cells have connection tubes exiting from the top, Type 63 on the front face and Type 65 on the upper portion of the cell. The light beam of the spectrophotometer is not intended to pass through the water jacket. PTFE stoppers are supplied as pictured.

Short Path Length, Flow Cells

Cell Types 48 and 49 are designed for use in various applications where a flow cell with a small path length and a large window surface area is needed. Flow tubes are fused to the front window of the cell, in the case of Type 49, the removable window. The cells will fit any spectrophotometer which can accommodate a normal cell with a 40mm path length. This allows introduction of the inlet/outlet tubes parallel to the light beam. The Type 48 is a fully fused cell.
