JULABO Refrigerated & Heating Circulators for heating and cooling are suitable for external temperature tasks and for temperature applications directly in the bath. A model from three different series' with different capacities can be selected. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. Depending on the model, the units are equipped with handles or castors for an easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. The compact assembly of each unit enables a space to be saved in the laboratory.

Item 685-SC
This double beam, scanning, UV/Visible spectrophotometer has a variety of programmed measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, DNA and protein analysis making it ideal for a number of applications.
The stable optics and two detectors measure your samples and reference simultaneously  providing superior measurement accuracy. 

The variable spectral bandwidth provides your experiments with robust detection and quantitation limits, as well as optimal data precision and repeatability. This flexible platform allows the user to comply with multiple regulatory agencies using one spectrophotometer- saving money and time. Three scan speeds are available with wavelength scan intervals of 0.1, 0.2, 1, 2 or 5 nm. The large sample chamber is outfitted with a 10 x 10 mm cuvette holder, but allows for an 8-position cuvette changer (order 83070-61 separately) for flexibility.

The integrated user interface provides local controls with the touch of a keypad. The colored graphical display is easy to read and will display spectrum as well as kinetic curves. Prism PC software is supplied with the spectrophotometer to assist the user with post-measurement analysis. The Prism PC software can be used to fully control the spectrophotometer and comes pre-loaded with methods for DNA analysis, including 260/280 and 260/230 ratios with 320 nm correction. Under the multi-wavelength measurement mode, up to 20 wavelengths can be measured simultaneously and quantitation curves can be created by measuring up to 200 standards.

Each sample reading is given a time and date stamp and easily connects to a printerthen simply push the print key to send data.
The included 63-Zero PC software allows you to take and control measurements remotely, and export data and results to Excel, Word, Power Point, and other software applications for storage, reporting, or presentation. Transmittance, absorbance, or concentration with factor value, as well as wavelength are simultaneously. The digital, dual-line LCD shows error messages, prompts, mode indication, and concentration units (ppm, mg/L, g/L, M, %, or blank).

Specifications & Description

The four new spectrophotometers in the Jenway 73 series range include models 7300 and 7310 which cover the visible region of the spectrum. The 7305 and 7315 models use a flash xenon lamp to extend the wavelength range into the UV region of the spectrum.

The basic models, 7300 and 7305, feature measurement modes for absorbance, % transmittance, and concentration. The advanced models, 7310 and 7315, introduce additional measurement modes such as scanning, kinetics, and quantitation.
