Abstract

Abstract This invention relates to a chemical manipulator adapted to automate analysis of liquids of µℓ units such as DNA sample. Within the body frame (1) are arranged a sample supply and discharging station, a mixing station, a separating station, and a drying station, each station being provided with a positioning device and a temperature control such as a thermostatic tank if necessary. Reaction containers are accommodated within a bucket (7) which can accommodate a plurality of reaction containers. The bucket (7) is automatically transported between the stations by means of a head element (6a) of a manipulator (6) which may be moved in three directions of x, y and z.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 104 words
A chemical manipulator comprising a centrifugal separator capable of accommodating at least more than one reaction container and a mixer device and thermostatic device, a dryer for drying said reaction containers, a reagent supplying device for supplying a reagent to said reaction containers, a transporting device for moving said reaction containers in a three-dimensional fashion and conveying said containers while being located relative to said centrifugal separator, said mixer device, said thermostatic device, said dryer and said reagent supplying device, and a controller for controlling said centrifugal separator, said mixer device, said thermostatic device, said dryer, said reagent supplying device and said transporting device.
Claim 2
Dependent Claim 104 words
A chemical manipulator comprising a centrifugal separator capable of accommodating at least more than one reaction container and a mixer device and thermostatic device, a dryer for drying said reaction containers, a reagent supplying device for supplying a reagent to said reaction containers, a transporting device for moving said reaction containers in a three-dimensional fashion and conveying said containers while being located relative to said centrifugal separator, said mixer device, said thermostatic device, said dryer and said reagent supplying device, and a controller for controlling said centrifugal separator, said mixer device, said thermostatic device, said dryer, said reagent supplying device and said transporting device.
Claim 3
Dependent Claim 39 words
A chemical manipulator as claimed in claim 1 wherein said thermostatic device is disposed in proximity of said reagent supplying device and reaction heat when the reagent is supplied to said reaction container is absorbed by said thermostatic device.
Claim 4
Dependent Claim 27 words
A chemical manipulator as claimed in claim 1 wherein said thermostatic device is disposed in proximity of said dryer to dry said reaction container while being heated.
Claim 5
Dependent Claim 41 words
A chemical manipulator as claimed in claim 1 wherein said reagent supplying device includes a nozzle, and a supplying end thereof comes into contact with and is disengaged from an inner wall surface of said reaction container at an acute angle.
Claim 6
Dependent Claim 129 words
A chemical manipulator as claimed in claim 1 wherein said mixer device comprises an eccentric shaft supported on a base bed and a first motor for rotatably driving said eccentric shaft, a swinging base plate swingingly supported on said base bed through a resilient member and pivotally supported on said eccentric shaft, a swinging case provided integral with said swinging base plate, a reaction container accommodating portion formed on said swinging case, a position detecting means for detecting a rotated position of said eccentric shaft, and a second motor for rotatably driving said eccentric shaft to a predetermined position in accordance with a signal of said detection means, characterized in that when said first motor stops, said swinging case is rested at a predetermined position by said second motor.
Claim 7
Dependent Claim 280 words
A chemical manipulator as claimed in claim 1 wherein said transporting device comprises a first support shaft rotatably provided on a base having a pair of.guide portions for guiding a pair of guide rods movable in a bi-direction, a first motor provided on said base to rotate said first support shaft, a rotational plate formed on one end of said first support shaft, a first electric detecting element provided on said base to electrically cooperate with said rotational plate, a second support shaft provided movably up and down in a direction parallel to said first support shaft in said base, a rack portion formed on said second support shaft, a second motor provided on said base and having a driving gear which meshes with the teeth thereof to move said second support shaft up and down, a support plate provided fixedly in a direction orthogonal to the length of said support shaft at the lower end of said second support shaft, a first and second rotational plates rotatably provided on both ends of said support plate, a connecting rod provided between said first rotational plate and said second rotational plate to connect said both rotational plates, and a head element rotatably provided on one end of said support plate, said head element being formed integral with said second rotational plate and having a locking rod at the lower end thereof, characterized in that said first support shaft and said first rotational plate are connected integrally whereby said head element is rotated in association with the rotation of said first support shaft, and said second support shaft is moved up and down whereby said head element is moved up and down.
