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.

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.

260/280 Ratio Validation Reference

When running DNA or RNA purity analysis on your spectrophotometer it is important to assure that your instrument is working correctly. Our DNA/RNA validation standard is a permanently sealed quartz cell which contains a stable solution which mimics the 260/280nm ratio of DNA and RNA. The reference is supplied with a certificate which lists the expected 260/280nm ratio of the cell and the confidence limit of the ratio. The validation analysis is performed by our ISO 17025 accredited laboratory and is traceable to NIST.

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.

Standard Glass Cuvettes

Standard rectangular cells or Macro cells, Type 1, are the most common cells used in analytical chemistry. The exterior dimensions allow the cells to be used with virtually every spectrophotometer and photometer instrument currently in use. These cells have an exterior height of 45mm, two clear windows and an open top. The walls of the cell and the bottom are smooth on the inside. On the outside, the light path windows are clear while the adjacent windows and the bottom are frosted or grey. Typically, windows are 1.25mm thick and each cell in this range is supplied with a PTFE cover.

Standard Glass, Quartz & Infrasil Cuvettes w/ stopper

Type 21 cells are identical to Standard Rectangular or Macro cells 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. Cells with a path length of greater than 20mm are supplied with two stoppers and the height of the cell body is 48 mm with an overall height including the stopper of approximately 53mm.

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.

Certified Reference Materials

To make your verification task easier, we have assembled our reference materials into sets which allow you to meet specific verification requirements. In addition, you can save money by purchasing a group of references

in a set instead of purchasing several references individually. We have sets which will allow you to meet the qualifications of the European Pharmacopoeia, the United States Pharmacopoeia and one set that will satisfy the requirements of both the EP and USP.

Micro Cells 18B Self Masking Black Walls in Glass & Quartz

Micro cells, Type 18, with a 2mm internal width are for use with sample volumes smaller than the standard rectangular or SemiMicro cells. The nominal working volume of this range represents only 20% of the standard rectangular cells Type 1 with the same path length.Full Detail

SKU:
18B-SOG-5

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.
