摘要: A needle assembly has at least one guide member supported by a first body for sliding movement between an extended position and a retracted position. A second body is attached to the guide member. A biasing member biases the guide member to the extended position. A liquid handling needle is coupled to the first body so sliding movement of the guide member toward the retracted position retracts the second body relative to the liquid handling needle. The second body is adapted to contact a sealed receptacle. The biasing member urges the guide member toward said extended position during insertion and during said removal of the needle from the receptacle whereby the second body remains in contact with the sealed receptacle as the guide member moves from its extended position to its retracted position during said insertion and from its retracted position to its extended position during said removal.
