An effective dry box can be constructed from a glove bag, quarter inch a d . aluminum tubing, elec""7 trician's taoe and rubber tubing. The advantages of the dry box are: The dry box is easily moved; since it is completely clear, it gives a. good view of the % ;,: working area; the aluminum tubing can be bent once inside the glove bag tg accomodate various shaped objects; the glove bag is easily replaced if it rrm,. becomes punctured or contaminated; and the c,.ws nrr crossed rather than a square construction of the front of the frank adds strength to the structure, and oermits the natural positi&ng and greater maneu;erability of the users' hands. The construction is ar follows, using a 37 X 37 ='+ X 25-in, glove hag. 1 ) Cut end bend the aluminum tubing as shown in the figure. to -prevent any sharp cutting edges and then tape 2) Attach the ends with rubber tubing and tape the joints. 3) The frame is bent in order to fit through the glove bag opening and then formed to the desired shape once inside the glove bag. 4) The gas inlet consists of apiece of aluminum tubing with the cut end taped to prevent puncturing the glove bag. The typical cost of constructing such a dry box is: Aluminum tubing '/,-in. 0.d. X 50 ft, $4.00; rubber tubing and tape, $0.50; and Glove bag, $6.50, giving a total of $11.00. os
