There's no substitute for EXAX RETESTED quality • EXAX RETESTED is America's No. 1 choice for accurate laboratory determinations simply because it is made and intended for that purpose. EXAX won't bounce, but it is thor­oughly annealed for toughness . . . will stand every day handling and usage.

The great value of EXAX RETESTED lies in certain exclusive advantages. It is a special formula of glass, precision-made by specialty craftsmen.

The fine deep graduations are oi a type which readily accepts the perma­nent fused-in blue filler. And . . . all

calibrations are marked and checked and retested with standards of highest precision.

So remember, if accuracy and fitness for the job are important, there is no subs t i tu te for EXAX R E T E S T E D glassware.

Look for the Kimble "K," the visible guarantee of invisible quality.
