These media are put up in regular sized tubes fitted with a tightly sealed 

 screw cap. No cotton plugs are used. The media are freshly prepared, and are 

 examined for sterility before being released. Culture media in tubes should be 

 stored in sealed cans to prevent evaporation, and under these conditions should 

 give good results indefinitely. Agar media should be melted and allowed to 

 resolidify in a slanted position or placed in a warm water bath for several minutes 

 to provide a fresh moist surface prior to inoculation. Media containing blood, 

 ascitic fluid, antibiotics or other thermolabile materials, should not be heated 

 prior to use.

BAGTO-DIPHTHERIA CULTURE TUBES (B1004T) 

 AND OUTFITS (B1005T) 



The advantages of early diagnosis in suspected cases of diphtheria require no 

 enumeration. As an emergency aid at times when delay may be of serious conse- 

 quence, we have prepared a Bacto-Diphtheria Culture Outfit which consists of 

 a Bacto-Diphtheria Culture Tube (an hermetically sealed and sterilized Loeffler 

 Blood Serum slant) and a sterile applicator with a data sheet. The outfit is com- 

 plete, neat and convenient. The hermetically sealed diphtheria culture tube pre- 

 serves the sterile medium indefinitely, keeping it ready for instant use. This tube is 

 etched for convenience in breaking. 



STERILE APPLICATORS IN TUBES (B1009T) 



Sterile applicators in tubes have been prepared for use in conjunction with 

 Bacto-Diphtheria Culture Outfits, as discussed above or for use in the collection 

 of other specimens.
