A unitary test tube holder insert adapted for receiving test tubes. The insert has a first ring to be secured in a hole of a test tube rack. A plurality of spring members extend at one end from the first ring towards a center axis of the ring to resiliently engage the outside of a test tube inserted into the insert. The spring members are connected at their other end to a second ring which is arranged coaxially with the first ring along the center access, and each spring member is curved towards the center axis to exhibit a straight section which extends parallel to the center axis and which resiliently engages the outside of a test tube inserted into the insert.
