JASCO V-730BIO

This is a double beam UV-Vis spectrophotometer with a fixed 1 nm bandwidth operated with an iRM controller that has a software package compiled for ”Life Science” applications. The use of a computer is not required, thus its little space allowances, its sample holders capable of measuring microliters of samples and its excellent optical properties allow for the determination of proteins and nucleic acids or kinetic measurements in science laboratories of biochemistry, biotechnology, and of other related fields. Due to the easy handling, the accessory detection system and the one-button measurement, everyday routine measurements can be carried out easily within a short time.

Beside the standard measurement methods, the control unit contains the software necessary for determining the protein/nucleic acid ratio (A260/A280, A230/A260, Warburg-Christian), the kinetic analysis program (according to Michaelis-Menten, Lineweaver-Burk, Hofstee and Eadie methods), a software for quantitative determination of proteins, performing calculations based on UV absorption, BCA, Bradford, Lowry and Biuret methods and a software for testing the DNA melting.

The standard cell compartment of the JASCO V-730BIO spectrophotometer possesses a sample and reference cuvette holder capable of receiving 10×10 mm cuvettes. There are also available optionally manual and automatic cell changers, cuvette holders for the long cuvettes, water thermostattable cuvette holders and cell changers.

Szczegóły

The Peltier thermostated cuvette holders are useful for measuring solutions at the controlled temperature, for studying the spectral changes depending on the temperature changes. The temperature setting takes place in the Spectra Manager II software (or on the IRM controller). Each Peltier thermostated JASCO cuvette holder has a magnetic stirrer whose speed can be controlled by a software. With the optional temperature sensors even the temperature of the solution can be measured directly.

Szczegóły

For the measurement of biological and biochemical samples, micro cell holders and microcuvette holders are available, which allow the measurement of micro-liter quantities easily, accurately and reproducibly. In the supply there are holder capable of measuring with only one droplet, as well as the capillary cell holder mounted with input/output lenses and the 8-position, rotatable micro cell holder.

Szczegóły

For measuring a large number of samples, in the supply there are available vacuum and peristaltic sippers, different types of optical path length flow cells, and auto samplers allowing full automation.
