The FP-8050 Series provide solutions for the broadest range of applications including QC, biomolecular structural studies, environmental monitoring and advanced materials science. The FP-8050 Series has many flexible options for academic or industrial research, teaching, or use in quality control labs. Users can have the greatest confidence in their measurements, with an optical bench specifically designed for the highest sensitivity, widest dynamic range, and exceptional spectral purity with automatic cut-off filters to exclude higher order diffraction.

The PU-4580 HPLC pumps can be used as part of any HPLC system or can be configured for stand-alone use with keyboard control.

The AS-4550 HPLC autosampler provides a range of options to suit any sample injection requirements. Any of these products can be added to an existing system with a keypad or optional RS232 control.

The UV-4570 is only 6 inches wide（15 cm）and can be used stand-alone or as part of a system for single wavelength measurement from the UV to Visible region（190-900 nm）with cassette-type tapered flow cells and user-replaceable lamps. Programmable wavelength switching and spectral scanning.

The LC-4500 Series is only 15 cm wide, offering the smallest HPLC systems. A simple isocratic or gradient pump with a UV-visible detector and manual injection valve requires only 15 cm. Adding an autosampler means the system is only 30 cm wide. The LC-4500 Series is stackable and can be used with the range of modules from the larger LC-4000 Series to make a more complex system.

JASCO developed the high-throughput CD measurement system combining an autosampler, syringe pump, and flow cell unit for use with the J-1500/J-1700. This system can accommodate two 96-well plates (up to 192 samples) and maintain a constant temperature prior to measurement. The system allows automated scanning measurements at predetermined parameters and/or temperature ramping measurements by using a Peltier thermostatted flow cell. In addition to CD, LD, and absorbance data, fluorescence can be simultaneously measured as an option. Software control allows samples to be recovered after measurement for further analysis. The analysis program allows batch processing of data including determination of Tm and secondary structure analysis.

Starna spectrophotometer cells and other quartz and glass assemblies are assembled using a fully fused method of construction. This technique, pioneered and used by Starna Scientific since the mid 1950s, ensures that cells are fused into a single homogeneous entity using heat alone, without intermediate bonding materials. All cells are then carefully annealed to remove any residual strain from the fusing process.

Three single-position Peltier thermostatted cell holders are available with a maximum light path length of 10 mm, to enable temperature control using the temperature control program. All feature a temperature setting range of -30 to 130°C with a measurement probe that can be placed inside or adjacent to cell and a magnetic stirrer to eliminate thermal gradients.

The MPTC accessories are designed to enable high sample throughput and productivity. The six-position holder for rectangular cells allows automated spectral scans and parallel thermal ramps on up to six samples at a time. All feature a temperature setting range of -30 to 130°C with a measurement probe that can be placed inside or adjacent to cell and a magnetic stirrer to eliminate thermal gradients.

Stopped-flow measurements involve the rapid mixing of two or more solutions to trigger a chemical reaction. The reaction kinetics can then be followed by CD, absorbance and fluorescence. All measurement techniques can be acquired on the same instrument when the stopped-flow system is paired with a J-1500 or J-1700 spectrophotometer.

Optical Rotatory Dispersion (ORD) provides information on chiral molecules even without chromophores, such as saccharides. It can be used to measure the chirality of non-absorbing samples and the determination of absolute configuration.
JASCO offers two methods of ORD detection: optical null and intensity measurement systems. The intensity measurement method, using a fixed analyzer, is simpler and more economical, while the optical-null approach, with its rotating analyzer, is intrinsically more accurate because the measurement is absolute. Since ORD is very sensitive to strain in the sample cell window, cylindrical cells are strongly recommended for use ORD measurement.

In the case of samples where only very small volumes are available, two microsampling accessories are now available. The microsampling disk (MSD-462) is designed for sample measurements as small as 2 µL with a 0.2 mm spacer and 10 µL with a 1.0 mm spacer. For thermal ramping studies of microvolume samples, JASCO also offers a capillary cell jacket (CAP-500), which allows for samples with volumes as small at 5 µL to be placed in a Peltier cell holder. Melting curves are now easily measured, including Tm, ΔS and ΔH values.
