1Introduction
1.1 Intended Use
The CAMAG UV Lamp 4 is designed for use in the TLC laboratory. It is likewise suitable for
many other applications such as checking authenticity of documents, banknotes etc., to
identify invisibly labelled objects in criminology, for mineralogical investigations and much
more.
•Long wave UV light 366 nm
Under this kind of UV light, substances with either inherent or reagent induced
fluorescence appear as bright spots, often differently colored, on a dark
background. Sensitivity of this detection method increases with the intensity of the
long wave UV light and also with the elimination of visible light. A fluorescent
indicator F254 contained in the layer neither contributes to, nor interferes with,
this detection method.
•Short wave UV light 254 nm
This kind of UV light renders substances visible which absorb at 254 nm, provided
the TLC layer contains a fluorescent indicator F254. These substances appear as
dark spots on a bright background. For this detection method, UV intensity and
complete elimination of visible light are less critical.
CAMAG Wavelength statement:
In literature both UV 365 nm and UV 366 nm are used to describe the UV light spectra
used for TLC/HPTLC usage. CAMAG decided to use UV 366 nm – thus, this (CAMAG’s UV
366 nm spectra) is identical to the light spectra described as UV 365 nm.
1.2 Precaution
•Please read this operating manual before starting the installation! This manual
contains information, warnings and instructions which the user has to follow to
ensure reliable operation of the instrument
•If the instrument is used in a manner not specified in this manual, the safety of the
user cannot be guaranteed
•Some interior parts of the instrument are under AC power. Careless and improper
use can cause injury. Unauthorized manipulations can cause damage
•This sign indicates (on the instrument and in this manual) that failure to take note
of the accompanying information may result in damage of the instrument
•The instrument is manufactured and tested in accordance with the respective
European safety publications shown on the Declaration of Conformity (DoC). The
instrument complies with safety class 1 and has been designed for indoor use only

Instruction Manual, November 2017 3
(IP 20). Furthermore, this device has passed the CAMAG Quality Assurance tests
and has been delivered in safe operation condition. For detailed instrument data,
see the chapter “Technical Data”
•Attention: For safety reasons the instrument may only be used for the purposes
described in the operating manual
•To avoid injury use adequate safety equipment (protective goggles, gloves etc. if
applicable) when working with the instrument
•Before first operation, check whether the voltage shown on the instrument
matches your local mains voltage. The power cord may only be connected to a
grounded, fused (not higher than 16A) outlet. Do not use extension cords without
ground contact
•When working with the fluids of the instrument, be sure to take appropriate
precautions (protect your eyes from direct contact with liquid)
•The instrument may be used only by properly trained laboratory staff
•The instrument may not be used in rooms with an explosion risk
•The instrument contains highly sophisticated electronics. It may be operated only
in a non-condensing atmosphere in the temperature range outlined in the chapter
"Technical Data". Before installation and use, the instrument should be acclimated
properly
•Use a damp lint-free cloth for cleaning the instrument surface. Do not employ
aggressive detergents
•Protect yourself and the instrument from electrostatic shock which can cause
damage to the electronic parts
•Only authorized personnel may open the instrument. Service and repair are only to
be performed by trained specialists. Use spare parts and consumables supplied by
CAMAG only. The warranty is voided if parts from other sources are used. Check
the service manual before you start service to reduce product-specific risks
•The power cord has to be removed before the instrument is opened. It is not
permitted to work on an instrument that has been opened and is connected to the
power supply
•Use only the original power cord type that was delivered with the instrument
•If the instrument is found to be defective, it must be switched off and steps must
be taken to ensure that it cannot be switched on by mistake
•Carry out all safety checks and preventive maintenance as recommended by the
manufacturer in order to assure your personal safety and the full functionality of
the instrument. Have an authorized service specialist perform any service not
described by this manual

Instruction Manual, November 2017 4
•See original manufacturers' manuals for further safety data on third party
equipment supplied with the system
•Lift/move/transport the system with the necessary care and with sufficient
manpower (install the transport security devices if applicable, transport it only in
the original packaging)
•This symbol indicates that this equipment must not be disposed of as unsorted
municipal waste but is to be collected separately as electrical and electronic
equipment (WEEE-Directive 2002/96/EC). To properly recycle the instrument or its
parts, you are requested to send the equipment back to the distributor, producer
or an adequate collection system at the end of its life. This will have potential
effects on the environment and human health

2Unpacking/Installation
2.1 UV Lamp 4
The UV lamp should only be operated in combination with the UV Cabinet 4.
Attention
High UV intensities can be harmful. Do not operate the UV Lamp without
precautions. Avoid direct and indirect radiation especially to skin and eyes.
Connect the UV lamp to a suitable power outlet with the supplied switching
power supply.
The lamp is switched on/off with the corresponding (254/366) button.
After 10 minutes, the timer automatically switches off the lamp
The 10 minutes timer can be disabled by pressing the respective button for more
than 3 seconds.
(Button LED is blinking)
2.2 UV Cabinet for UV Lamp 4
The UV Cabinet is used for inspecting TLC plates under UV light in a bright environment.
A glass filter protects the eyes against UV light reflected during inspection through the
viewing window.
Attention
•Your eyes are protected against reflected UV light by a glass filter in this setup.
Make sure to wear a face mask or protective goggles if you are not looking
through the viewing window with the UV lamp switched on.
•Consider UV radiation intensities in chapter 0: Never work with unprotected skin
areas under UV light, e.g. for marking plates or adding texts!
Place the UV Cabinet 4 on a suitable surface such as a laboratory bench with the
opening (shutter) towards the user.
Remove the shipping protections at both sides of the UV filter (see Figure 1).

3.2 Safety Mode
The Lamp has a built in safety mode which is active when either the lamp is tilted more
than 30° or when the lamp temperature reaches a certain limit.
It is indicated by the blinking of the green or blue LED, depending on the active tube.
The Safety Mode will be deactivated as soon as the normal operating conditions are met
again.
3.3 Error Mode
The Lamp has a built-in error mode which is active when either an over-current or an over-
temperature is detected. It is indicated by alternating blinking of the green and blue LED.
The Error Mode will be deactivated by simultaneously pressing the 254 nm and 366 nm
button or a power on reset.

4Service and maintenance
Attention
•Before opening the lamp, detach the power cord from the lamp.
4.1 Replacing fluorescent tubes
Over time the UV tube intensity decreases. It is therefore advisable to replace the tube
approximately every two years if the lamp is frequently used.
Before replacing tubes, detach the power cable from the lamp.
Unscrew the screws in the filter holding plate.
The old tube can now be taken out of the socket by turning it approx. 90°.
Insert the pins of the new tube into the sockets and turn the tube about 90°
again.
Tighten up the screws in the filter holding plate.
Reconnect the UV lamp to the power cable and check that it is working properly.
4.2 Cleaning
UV Lamp 4
Use a soft, moist cloth or tissue for cleaning the UV Lamp.
UV Cabinet for UV Lamp 4
Use a soft, moist cloth or tissue for cleaning the UV Cabinet.
Procedure for cleaning the UV filter:
Place the UV Cabinet on a table with the viewing window faced down and open
the shutter. Pull the releases away from the glass filter (see detail in Figure 3) and
remove the UV filter for cleaning.
Use a soft cloth or tissue to wipe off the UV filter.
