A coloring-decoloring-drying apparatus for electrophoresis comprising a coloring-decoloring container having an opening used for inserting a carrier, pouring coloring and decoloring liquid agents and other purpose and rollers arranged in the vicinity of the opening of said coloring-decoloring container, and adapted in such a manner that a carrier sent from an electrophoretic apparatus is inserted into said coloring-decoloring container by operating said rollers, the rear end of the carrier is held between said rollers, coloring and decoloring liquid agents are poured into said container for coloring and decoloring said carrier while it is held in the condition described above, and then the carrier is dried by blowing hot air through said opening. Said coloring-decoloring-drying apparatus for electrophoresis is so designed as to be capable to performing coloring, decoloring and drying of a carrier without injuring or tearing the carrier.

In a method for calibrating or checking a densitometer section of a cataphoretic apparatus use is made of a calibration film comprising a transparent and flexible sheet and a pattern applied on the sheet and having a known density and the calibration film is fed into the densitomater with the aid of a mechanism for feeding usual sample bearing films. After the calibration for the densitometer has been completed using the introduced calibration film the film is discharged out of the densitometer with the aid of a mechanism for discharging the usual sample bearing films.

A device for moistening a blood serum bearing film before it is wetted with a buffer solution comprises a conveyor roller assembly including a first roller having its surface layer formed of sponge and partly maintained in immersion in a buffer solution and a second roller disposed above and in abutting relationship with the first roller, wetting means for passing a blood serum bearing film between the rollers to supply a buffer solution thereto from the surface layer, and a vapor ejection tube disposed adjacent to the both rollers for spraying a vapor to the film before it is wetted.
摘要:
A method for determining boundary points in electrophoresis comprising a step to determine points on the abscissa corresponding to peak tops on a densitogram traced on the basis of electrophoresis of a standard sample as standard positions, a step to locate positions corresponding to said standard positions on a densitogram traced on the basis of electrophoresis of an unknown sample, a step to determine the point corresponding to the lowest concentration among points having minimum values between each pair of neighboring standard positions as the normal boundary point and a step to calculate an integral or a value proportional to the integral of each fraction delimited by the boundary points thus determined.
摘要:
An electrophoretic apparatus comprising a pair of endless belts for conveying a film into and out of the apparatus, filter paper supports on which edge portions of filter paper sheets are placed and filter paper retainers arranged above the filter paper supports. The electrophoretic apparatus is arranged that, after the film is conveyed into the apparatus by means of endless belts, the film is moved upward by moving the filter paper supports upward and thereby holding the edge portions of film between the filter paper supports and filter paper retainers, edge portions of film are pulled in the direction opposite to each other and, then, the film is energized, the electrophoretic apparatus being thereby arranged that the film is energized in the state that it is free from slack so that favorable fractionated patters are obtained.
摘要:
A heat developing device for locally heat developing a dry photosensitive film composed of a heating unit for locally heating a portion to be heat-developed of the photosensitive film and a cooling unit surrounding the heating unit and placed in contact with the periphery of the portion to be heat-developed of the photosensitive film. The cooling unit functions to prevent the thermal effect applied to the heat-developing portion of the photosensitive film from being transmitted to the remainder of the photosensitive film.
摘要:
In a distributing method for sucking a desired amount of a sample liquid in a sample vessel and discharging the thus sucked sample liquid into a reaction vessel, a probe for sucking and discharging the liquid is connected to a syringe driven by a pulse motor. A photoelectric detector is provided for detecting whether the sample liquid is existed or not up to a predetermined level in the sample vessel and an actual amount of the sample liquid aspirated by the syringe is detected by a counter which counts clock pulses during the aspirating operation. When the liquid level descends lower than the predetermined level, the counting operation is stopped. The actual amount of the aspirated liquid in the probe is compared with a desired amount stored in a memory. When the actual amount of the sucked liquid is smaller than the desired value, an alarm is produced.
摘要:
A densitometer comprising a recorder so adapted as to be capable of recording a set of analytical data obtained with a photometric system twice at a definite recording interval, an index arranged at a position apart by a distance equal to said recording interval from the recording pen of said recorder, a switch for setting boundary point and another switch commanding erasure of boundary point, said densitometer being so adapted as to permit setting and erasing boundary point by using the first recorded densitogram and said index.
