Single and dual port versions of the keyed fillers fitted to TEC4 and TEC3 vaporizers, respectively, were examined. The single port filler performed satisfactorily, provided that it was correctly used and properly maintained. Design deficiencies in the dual-port keyed filler were found which accounted for many of the problems described by users. The keyed bottle adaptor could be improved by an increase in its length and the provision of two openings into the outer tube at the bottle end.
分别对安装在TEC4和TEC3蒸发器上的带钥匙填充器的单端口和双端口版本进行了检查。单端口填充器只要使用正确并得到妥善维护，就能令人满意地工作。发现双端口带钥匙填充器存在设计缺陷，这就是用户所描述的许多问题的原因。带钥匙的瓶适配器可以通过增加其长度并在瓶端的外管上设置两个开口来改进。
