Caution: Do not use powdered detergents to clean the screen as undissolved particles
may damage the screens coating.
Cleaning Protocol for Imaging Screen-K and Imaging Screen-HD
1. Handle the screen only by the edges. Avoid touching the screen coating with anything
sharp, such as fingernails. The screen is coated with a thin layer of plastic and
scratching this protective layer could damage the screen, making that area unusable.
2. Apply a small amount of cleaner to a soft, lint-free-cloth and gently wipe the screen. It is
recommended to use Kodak Intensifying Screen cleaner and Antistatic Solution
Catalog# 1064930 from Kodak.
3. With a dry section of the cloth, gently wipe the screen to remove any excess moisture.
If the screen had radioactive contamination, properly discard the radioactive cloth.
4. Erase the screen to background before use.
5. Repeat the contamination check above.
Cleaning Protocol for the Imaging Screen K/Tritium
Caution: The phosphor matrix of the tritium screen has no protective barrier and should
NOT be cleaned with or exposed to any liquids.
Any particulate matter should be gently removed with a soft, dry brush or gentle dry gas
stream.
The screen should be used only with ³H, any other isotope will contaminate the screen.
5.2.4 Storage of the Imaging Screens
Always erase the screen prior to storage. The surface of the screen should be completely
protected. Do not place heavy objects on top of the imaging screen. With proper care the
imaging screen should maintain its performance through years of use.
Always store the screen "flat" in an exposure cassette, in the original shipping box or storage
bag.
5.3 Exposure Cassette Maintenance
These devices do not require regular maintenance other than regular cleaning to remove
any residue or possible radioactive contamination. To clean, wipe with a lint-free paper
towel moistened with a mild detergent solution such as Bio-Rad's Cleaning Concentrate
(Catalog #161-0722) that has been diluted 1 in 20 with distilled water.
5.4 Screen Eraser Maintenance
The white plastic filter requires occasional cleaning to remove accumulated dust from its
surface. To clean the filter, gently wipe with moist, lint-free paper or a soft cloth. Do not use
abrasive cleaning solutions, as they will scratch the filter.
5.4.1 Changing Bulbs
To order replacement bulbs (Catalog #170-7869) contact either Bio-Rad Laboratories or
your local distributor.
The Screen Eraser uses four 15-watt fluorescent light bulbs. To replace a light bulb, use
the following procedure.
