Vial locator and sensor

摘要: An analytical instrument sample vial positioning and sensor device. A radius or cone-shaped body portion (48,70) extending below a surface contacts loosely held (14) having flexible septum (34) thereon. The shaped is biased downward resulting in the relative movement between tending to center under (48,70). longitudinal bore (46) through permits insertion of syringe needle (84) for removal be analyzed. pre-positioning prevents needles from being bent broken due inappropriate alignment with respect (34). (60) incorporated detect presence absence (14).
