Abstract: An analyzers that comprise a dispensing unit for dispensing a liquid and having a detachably installed dispensing tip, a transfer unit for transferring the dispensing unit, and a controller for controlling the transfer unit; wherein the controller monitors whether or not the dispensing tip is installed to the dispensing unit during a transfer period of the dispensing unit by the transfer unit and controls the transfer unit based on the monitoring result is disclosed. An analyzing methods are also described.

Abstract: A nucleic acid detection apparatus is described that include: a nucleic acid detection apparatus for amplifying a nucleic acid in a reaction solution accommodated in a detection container and detecting the amplified target nucleic acid, the nucleic acid detection apparatus including a plurality of detectors having a light-emitting part for irradiating light on the detection container and a light-receiving part for receiving the light from the detection container, and a controller for adjusting the variance of photoreception signals of each light-receiving part to a uniform photoreception signal level for the plurality of detectors based on the variance of the detectors.

Abstract: A sample analyzer allowing miniaturization and sufficiently prompt analysis is obtained. This sample analyzer comprises a dispensing part rendered movable above a sample container set part, a reagent container set part and a detection part for sucking a sample and a reagent from the sample container and the reagent container respectively while discharging the sucked sample and the sucked reagent into the detection container. The detection part is arranged oppositely to the sample container set part and the reagent container set part.

Abstract: A mixing apparatus, which can prevent possibility of mixing nonuniformity and contamination, employs a small and simple mechanism, and is advantageous with respect to costs. A vessel is gripped and held from the right and left sides by a hand member. The hand member horizontally rotatable by an urging power of a coil spring at the bottom of a support member. A vibration motor comprises a DC coreless motor body and an eccentric weight, the weight being eccentrically mounted to a motor shaft of the motor body. The rotation of the weight allows the motor body to eccentrically rotate, whereby the support member conically revolves and vibrates. The weight has a semicircular cross section. The support member is connected to a mobile member for moving the support member through a resilient member to allow the conical revolution of the support member.

Abstract: An adhesive composition comprising(A) 100 parts by weight of an elastomer consisting of (I) 30 to 100% by weight of a thermoplastic elastomer expressed by the general formula (S-B).sub.n or (S-B).sub.n-1 --S in which S is substantially a polystyrene block, B is substantially a polybutadiene block, and n is an integer of from 2 to 10, and (II) 70 to 0% by weight of a thermoplastic elastomer expressed by the general formula (S--I).sub.n or (S-I).sub.n-1 --S in which S is substantially a polystyrene block, I is substantially a polyisoprene block, and n is an integer of from 2 to 10, and(B) 50 to 250 parts by weight of a hydrocarbon resin containing 40 to 95% by weight of a 1,3-pentadiene unit and 60 to 5% by weight of an .alpha.-methylstyrene unit in the polymer chain and having a softening point of 60.degree. to 140.degree.
