With a variety of additional program packs and accessories, the Bio–Mini can be easily customized for any application or sampling requirements. With the versatility that the Bio–Mini provides for DNA and protein analysis, it really is the next "Mini" thing for Biotech.

The AA-7000 series' 3-D optical system is capable of producing maximum performance for both flame detection (Pb 0.015 ppm) and furnace detection (Pb 0.00005 ppm). This is achieved through optimal adjustment of the light beam and digital filter, and by using optical components that restrict light loss.

The optical double-beam photometric system is automatically set for flame measurements, and the high-throughput, single-beam photometric system is automatically set for furnace measurements. With a new graphite furnace design, the AA-7000 Series has achieved improved lower limits of detection for furnace analysis in all fields, as compared to Shimadzu's previous series designs.

The AA-7000 has the smallest footprint of any flame or furnace AA spectrophotometer on the market, combining flame and furnace system mounts in the same compartment. When combined with an optional auto atomizer changer, the AA-7000F creates an integral burner and furnace that remains permanently installed in the combustion chamber. It supports flame analysis of high-concentration samples and furnace analysis of trace samples without changing the atomizer unit.

The AA-7000 series gives users a single high-performance autosampler for both flame and furnace, saving capital cost and set-up time. The ASC-7000 autosampler can layer a solution in the furnace like competitive systems, but takes analysis a step further by truly mixing a sample with four other solutions, such as matrix modifiers, matrix matching, dilution or standard addition samples, for a higher level of automation. Optimal background correction methods are installed as standard, and a high-speed self-reversal method provides correction over a 185 nm to 900 nm range.

Additionally, because safety is an important consideration for flame atomic absorption spectrophotometers, the AA-7000 series are also the first instruments in the world to be equipped standard with a vibration sensor that extinguishes flames automatically. Other safety features include a multimode automatic gas leak check and automatic air-N2O switching for flame-specification instruments, and an argon gas pressure monitor and over-current protection unit for furnace-specification instruments.

Affordable and Easy to Use Standards for:

• UV/Vis Spectrophotometers

• Microplate Readers

• Colorimeters

• And More!

The In-Spec® product line is constantly growing and now includes standards to check not just photometric accuracy but also wavelength, stray light, and resolu-tion for a variety of instrumentation in-cluding the increasingly popular short pathlength / small sample instruments.

By using a NIST-traceable standard you can verify that an instrument is in fact performing as it should. This provides validity to the data that is collected with the instrument.

Many of the solutions that are available are either very costly, toxic, or not flexible and can't meet your exact specifications. GFS Chemicals however has the ability with its In-Spec® Standards to find a solution that will better fit your requirements.

The RT100 consists of a hand-held spectrometer unit with an integrated measuring head (45 degrees; / 0 degrees; measuring geometry) for precision colour measurement and control of regular surfaces. The RT200 has a similar spectrometer unit but is supplied with a flexible, fibre-optic measuring head (0 degrees; / 0 degrees; measuring geometry) for colour measurement of small areas, challenging shapes or relatively inaccessible places.

The RT100 and RT200 combine advanced microspectrometer technology with the computing power of a PC. The spectrometer units link to a standard PC computer with Lovibond^® RT Colour Measurement System software installed for instrument operation and for presentation, analysis and logging of reflectance data.

Results can be expressed in a choice of colour values and colour difference measurements:

CIE XYZ tristimulus values

CIE L*a*b* colour space

CIE L'u'v colour space

CIE x y Y chromaticity coordinates

CIE L*C*h colour space

��E*, ��L*, ��a*, ��b*, ��C*, ��h* colour differences

Whiteness Index

Reflectance

Yellowness Index

Metameric index

The software, which works under MS Windows^® 95/98/NT, displays a choice of colour spaces or reflectance curves, allows input and selection of reference values, will average multiple measurement and includes a verbal indication of colour differences. It includes the facility for data export to ASCII files and direct data export into MS Excel.

Lovibond® RT 300 - 400 - 500 Portable Spectrophotometers

Advanced colour measurement in the laboratory, plant or field

• Lightweight, compact, portable instruments
• Diffuse/8 sphere or 0 / 45 optical geometry
• Large, easy-to-read graphical LCD display
• Opacity and colour strength measurement
• Flip-back target shoe for flexible use
• Rugged construction
• Rechargeable battery for remote use

The RT 300 - 400 - 500 series of versatile, portable spectrophotometers is designed to give fast, precise and accurate colour measurement information on a range of products. They provide absolute and difference measurements in various colorimetric systems including CIE Xyz, CIE Yxy, CIE L*a*b*, Hunter LAB, CIE L*c*h*, CMC and CIE 94, Whiteness and Yellowness per ASTM E313-98, Metamerism Index and DIN 6172.

The RT 300 - 400 - 500 series stores up to 1024 standards with tolerances for easy pass/fail measurement. A red/green LED-illuminated indicator and the LCD display provide visual confirmation of results. A tone also sounds to indicate a fail result. To allow the operator to take quality-control readings in a time-efficient manner without having to create tolerances or store data, it is also possible to take a quick measurement and comparison of two colours.

The RT 300 and RT 500 include a special 'project Mode'. Each project maintains a group of standards from which the instrument selects the closest colour for comparison with measured samples. The projects mode helps to organise standards eg a project can represent a customer that has several standard colours for a particular product line.

The iLab Visible Handheld Spectrophotometers capture spectra and compute results for easy downloading and reporting. Units run on three AA batteries, making them portable while taking up no lab space. The disposable sampling system makes cleanup easy, while eliminating the potential of contamination between samples.
Easily program units with the easy to use software to make sure all processes are followed. Connect unit to a computer via USB connection to transfer data and methods. Units are available with one of three software systems. The i-LAB Spectrum Lite software allows for basic downloading of purchased methods and uploading of spectra and results. The i-LAB Spectrum Standard software allows for spectra acquisition, data handling, and method development.
