Serine and theonine were hydrolyzed in newly designed tubes featuring O-ring joints. Design features of the apparatus include 1 a Teflon stopcock sealed to an O-ring connector tube, 2 a Teflon plug secured by a new sealing clamp, and 3 a Teflon O-ring used in the O-ring joint. This technique was compared with the sealed-tube procedure the above amino acids were equally decomposed in both types of apparatus. The O-ring joint tube can be reused, thereby eliminating sealing and opening of evacuated hydrolysis tubes. Author
