General Information
Permissible Exposure value. Therefore, for Class 1 LASERS the
output power is below the level at which it is believed eye damage
will occur. Exposure to the beam of a Class 1 LASER will not result
in eye injury. Class 1 LASERS may therefore be considered safe.
However, Class 1 LASER products may contain LASER systems of
a higher Class but there are adequate engineering control
measures to ensure that access to the beam is not reasonably
likely. Examples of such products include LASER printers and
compact disc players. CDRH assession number 0510555-02.
Data: 0.3 mW; wavelength = 650 nm
2.1.4 Chemical and Biological Safety
DANGER
Potential Chemical/ Biological Exposure Hazards. Handling
chemical samples, standards and reagents can be dangerous.
Users of this product are advised to familiarize themselves
with safety procedures and the correct use of chemicals, and
to carefully read all relevant Material Safety Data Sheets.
Normal operation of this instrument may involve the use of
hazardous chemicals or biologically harmful samples.
• The user must observe all cautionary information printed on the
original solution containers and safety data sheet prior to their
use.
• All waste solutions must be disposed in accordance with local
and national law.
• The type of protective equipment must be selected according to
the concentration and amount of the dangerous substance at
the specific workplace.
2.2 Overview of product
The DR 2800 spectrophotometer is a VIS spectrophotometer with a
wavelength range of 340 to 900 nm. The instrument comes with a
complete set of application programs and multi-language support.
The DR 2800 spectrophotometer contains the following application
modes: Stored Programs (pre-installed tests), Barcode Programs,
User Programs, Favorite Programs, Single Wavelength Mode,
Multi-Wavelength Mode and Time Course Mode.
The DR 2800 spectrophotometer provides digital readouts in direct
concentration units, absorbance, or percent transmittance.
When a user-generated or programmed method is selected, the
on-screen menus and prompts direct the user through the test.
This menu system also can be used to generate reports, statistical
evaluations of generated calibration curves, and to report
instrument diagnostic checks.
