Spectroscopy and Spectrophotometers

Product Details:

• Narrow bandwidth with 4-cell convenience
• Economical non-scanning general purpose spectrophotometer

• Obtain accurate results for routine spectrophotometric analysis with these high-quality instruments for cost-conscious labs. Economical single-beam spectrophotometers are perfect for quantitative analysis using a wide variety of quality control protocols.
• The bandwidth of these filter-based instruments produces precise response to transmittance changes for visible spectrum methods. Filters auto-adjust to ensure accuracy. Save time and improve efficiency with four-position cuvette holders (optional on model 83055-30).
• Use RS-232 and USB ports for optional interfaces-directly to a printer or to a computer utilizing optional application software. Software facilitates standard curve creation and absorbance versus time graphs and includes a wavelength scanning feature.
• Visible Spectrum Spectrophotometer (model 83055-30) has a small footprint for minimal bench space utilization. Optional four-position cell holders are available for either 10-mm or 50-mm pathlength cuvettes. Order optional power cable 83055-25 for 230 VAC operation; CE listed.
• Includes a 7-ft. cord and dust cover. Also includes twelve 10-mm test tubes and a cuvette adapter.

• Be more accurate with precise response to transmittance changes and filter auto-adjustments
• Easily connect to PC or printer with RS-232 and USB ports

Product Details:

• Store up to 200 test methods for your demanding lab environments
• Software-driven DNA/RNA/protein/kinetics analysis

• 7-ft detachable cord, dust cover, four-position 10 mm cuvette holder, four glass cuvettes, and two quartz cuvettes.

• The 4 nm bandwidth of these single-beam instruments produces precise response to transmittance changes for UV/visible spectrum methods. Four-position cuvette holders save time and improve efficiency.
• Use the RS-232 or USB ports for connecting directly to a printer or to a PC. Order optional Peltier temperature controller and/or sipper system for total spectrophotometric utility. Peltier controller regulates temperature between 15 and 40 DegreeC.
• UV/Visible spectrophotometers have a low profile with a large LED display which can be read from any angle. Optional software 83057-65 lets you create standard curves and absorbance vs. time graphs and also includes a wavelength scanning feature.

• Leverage software for DNA/RNA/protein and kinetics analysis
• Be more productive with included four-position cuvette holder
• Responds precisely to transmittance changes for better results
• Optional Peltier temperature controller and/or sipper system for total utility
• Create standard curves and get wavelength scanning feature with optional software

• A 7-ft (2.1-m) detachable cord, dust cover, two-position 10-mm cuvette holder, four glass cuvettes, and two quartz cuvettes.
