Dear Customer,
Thank you for buying one of our UVT Transilluminators.
All our products are developed and built with great care, keeping the needs of our customers as our main
focus. We check each unit carefully before it leaves our workshop.
We therefore believe that you will be entirely satisfied with the design and operation of this unit. However,
since even the currently best things can often be improved, we welcome any suggestion you might have.

Safety Advice
UV radiation is harmful to eyes and skin!
All Herolab UVT transilluminators exception of the economy models are equipped with an UV
impermeable cover. All the same, safety glasses or goggles protecting the eyes from UV radiation should
be worn at all times, since accidental unprotected exposure of the eyes can lead to irreversible damage.
The skin is damaged by UV radiation as well, and the effects of longtime exposures are not yet well
known.
If it is necessary to work without the protective cover, a face shield should be worn. The skin of the hands
and arms should be protected by gloves and long sleeves.
Wear safety glasses (Cat. No. 29 93 100)! If necessary, wear face protection (Cat. No. 29 93 000)!
Blue Light radiation could be harmful for your eyes!
When working with a Blue Light LED transilluminator orange safety glasses should be worn. In the
literature it was told of eye problems because of blue light. There are no clinical studies thereon.
Wear safety glasses (Cat. No. 29 93 150)!
Due to the rather powerful intensity of LEDs, one should not look into the light similar to any bright light
source.
The voltage supplied must be the same as indicated on the name plate. The appliance may only be
connected to an earthed outlet.

Operation
Installation
Unpack the transilluminator and its power cord and check if anything is damaged.
Do not use damaged appliances!
For transport damage, notify the forwarder, for other damage, notify the manufacturer or distributor.
The transilluminator should be placed on a level work surface, so that the air can circulate free.
The voltage supplied must be the same as indicated on the name plate. The appliance may only be
connected to an earthed outlet.

Operation - UV
For combined UV / White Light models, set the selector switch to UV.
Check that the intensity switch is set to High. Only on High setting will all tubes light. Put the sample to be
illuminated (e.g., the electrophoresis gel) onto the filter and close the protective cover (the Ecomomy
models have no protection cover). For your safety, wear UV protection glasses.
The cover stays open at any angle between 0° and 90°. For preparative work, it is recommended that it is
used as supplementary face protection to the usual eye protection. During instant photography or
photodocumentation it should be placed as shield between the UV table and the user. It cannot cover the
gel in this case, because humidity from the gel condenses on the lower surface of the cover and blurs the
photograph.
If one of Herolab's Darkroom Hood is used, or the transilluminator is part of a MiniDoc system, the
protective cover is not necessary, because the hood is impermeable to UV and the transilluminator is
switched on from outside. All the same, safety glasses should be worn, so that accidental opening cannot
damage the eyes.
Switch on the Power switch, it will glow.
After all tubes have started, it is possible after about 10 seconds to set the intensity switch to Low. The
intensity is then lowered to about 70 % of maximum intensity. Use the knob to adjust the intensity if you
have a Variable model. This way, damage to the sample due to overexposure is reduced during
preparative work.
Additional you can choose the wavelengths with a Multi Wave model.
Remark: The Multi Wave models with 3 wavelengths have no High/Low switch.
As soon as the UV light is no longer needed, turn the transilluminator off. For this, set the Power switch to
the 0position, so that it stops glowing.
Operation - White Light
Place the sample on the white light plate.
For combined UV / White Light models, set the selector switch to White.
Using the Power switch, turn on the appliance.
When the white light is no longer needed, turn it off with the Power switch.

Operation - Blue Light
Place the sample on the blue light plate.
Using the Power switch, turn on the appliance.
Use the orange glasses or an appropriate filter to be safe of the radiation and to make parts of the sample
visible.
When the blue light is no longer needed, turn it off with the Power switch.
Cleaning and Care
We recommend to clean the filter plate and, if necessary, the housing with a damp cloth after each use to
prevent buildup of dirt. If necessary, soap or a mild detergent can be used.
The housing and filter plate are stable to alcohol and other desinfectants, but the clear cover and the Blue
Light Transilluminator are not. Remember that several window cleaners contain alcohol, they must not be
used.
Do not immerse the appliance in water!
Maintenance
Always disconnect the appliance from the mains before working on the unit!
Adjusting the cover hinges
Most of Herolab 's UVT transilluminators are equipped with special hinges to keep the cover open at any
desired angle. They have to be readjusted from time to time.
Turn the adjustment screw clockwise to tighten the hinge, restraining the movement. Turn it
counterclockwise to loosen the hinge, making movement easier.

Exchanging the cover
If the cover gets damaged, e.g. by shock, it can easily be replaced. A phillips screwdriver and a 7 mm
wrench are needed. Loosen and remove the cover fixing screws, using the wrench to keep the nuts from
turning. Remove the cover.
Fix the replacement cover using the same nuts and bolts. Take care that the two washers, one plastic and
one metal, are used, with the plastic one nearest the cover.
Caution:
Always disconnect the appliance from the mains before working on the unit!
Exchanging the filter plate
Herolab LongLife filters are sturdy and long-lived, however, they can be damaged, e.g. by using them as a
cutting surface. With short wave UV radiation (254 nm), a diminution of the UV transmission (called
solarization) is observed after several thousand hours of operation.
(The filter glass has high manufacturing tolerances in thickness which may show as streaks. The filter
glasses are checked to make sure UV transmission is not impaired by these. Therefore, streaks in the
filter glass cannot be recognized as grounds for complaints, because they do not have effects on function
or durability of the appliance.)
To remove the filter plate, remove the four screws at the lateral sides of the plate and lift it off. Set the
replacement filter plate on the base and fix it again with the four screws.
Exchanging tubes
For all UV tubes, radiation intensity diminishes with time. It is therefore recommended to always exchange
all tubes at the same time, to achieve homogeneous radiation intensity.
Caution! The tubes get hot during operation! Let them cool down before touching them!
To exchange the tubes, take off the filter plate as described above. Then pull open the three snap locks
on the back (Standard and Advanced models) and take off the rear panel (taking off the rear panel is not
necessary if you have a Ecomomy, Blue Light or UVT-14 model)

UV Light
With ¼ turn, free the tubes from the contacts and take them out upwards. Set in the new tubes from
above and with ¼ turn, fit them securely in the contacts (some resistance must be overcome).
After exchanging all tubes, put the rear panel back into place and fix it with the snap locks, which have to
snap audibly. Replace the filter plate as described above.
Important Remark: Before reusing the unit, assemble it completely and check it is functioning
properly!
