• Linen cord. Christopher Clarkson has just completed the arrangements for a second making of Best Quality Linen Cord for bookbinding. Colophon Bindery has been selected to distribute this cord to bookbinders and conservators in America. However, it is necessary to act promptly so that the group order can be attached to the making now under way. Delays could mean that we would have to wait for a particular ply to be made again. Base price will be between $23 and $25 per spool (weighing 1 kg or 2.2 pounds) plus transportation and customs. For information and order forms write Colophon Bindery, 1902 N. 44th St., Seattle, WA 98103 (206/633-1759).

  The durability and continued effectiveness of ultraviolet filters is often questioned, but without reason. Little is published on this subject, or reported at meetings, because they last so long. One informed source said that it is even possible that they get better as tine goes by.

Equipment

• A disinfection unit for humidifiers is described in the March Conservation News (UKIC) by Graeme Scott, Conservator with Dundee Art Galleries and Museum Service. It uses ultraviolet light instead of chemicals, and is far more effective. The unit is the Hanovia UV Disinfection Unit Model 102, which is supplied by Hanovia Ltd., 145 Farnham Rd., Slough, Berks SL1 4XB, England. The American supplier, if one exists, is unknown. Price: about £200 without pump and filter.
• Scott Kellar (mow at Northwestern University Library) writes, "Electronic digital pH meters are getting cheaper and are easy to use. I recently purchased a pHep pH electronic paper for forty bucks from Cole-Parmer Instrument Co. (1-800-323-4340). It's a battery-operated pocket model with a 0-14 range with � .2 pH accuracy. This is, of course, useful when a slurry can be made of the paper; but new materials should be tested as a matter of course with fluctuations in quality so commonly reported.... It's best to keep the slurry thin (water-like) and agitate while your re testing. Be sure to order a pH 7 buffer solution with the meter."
• Karl Trobas's "paper washing machine" is now available through Ingenieurbüro Klaus Voss, Postfach 1250, 8762 Amorbach, West Germany. Voss has bought all rights for manufacturing and selling of the machine, which they have been making since the autumn of 1985. Price: about £5,500. (A previous story on this machine is on p. 68 of the July 1985 issue of AN.)
• Coroplast, or extruded polypropylene corrugated or channeled sheeting, is used in museums because of its stability and versatility, reports Carl Schlichting in the March 1987 IIC-CG Newsletter. It is an ideal material for boxes, except for one thing: adhesives do not stick to it. He describes a way he has found around this problem, by use of a Bostik Hot Melt Gun #260 and resin sticks, to make "rivets." He does not give the source of the Coroplast.
