Provided is a method for producing a cell contained base, the method being capable of providing a cell contained base highly accurately controlled in number of nucleic acid molecules contained in a low-concentration nucleic acid standard sample, the method including a liquid droplet discharging step of discharging a cell suspension in the form of a liquid droplet with a liquid droplet discharging unit onto a base including at least one cell contained region; a cell number counting step of counting a number of cells contained in the liquid droplet with a plurality of sensors from two or more directions while the liquid droplet is flying into the cell contained region; and a liquid droplet landing step of landing the liquid droplet in the at least one cell contained region in a manner that a predetermined number of cells are located in the at least one cell contained region.

Method for producing cell contained base and method for evaluating equipment

Provided is a container () including a base material () including a plurality of concave portions (); a recognition unit () disposed on the base material and configured to recognize the base material; and a storage unit () disposed in a position other than a measurement region of the base material and configured to store information on biomaterials contained in the plurality of concave portions, wherein the recognition unit and the storage unit are allowed to correspond to each other.

Container and calibration standard plate

Provided is a liquid discharging head including: a membranous member including a discharging port through which a liquid is discharged; and a displacement member disposed at membranous member's one side at which the liquid to be discharged through the discharging port is provided and configured to displace a position of the membranous member to cause the liquid to be discharged through the discharging port.

Liquid discharging head and liquid discharging apparatus

A droplet forming device is provided. The droplet forming device includes a liquid holder configured to hold a liquid, a film having a discharge hole, two or more vibration generators configured to vibrate the film, and a driver configured to apply a driving signal to the vibration generators. One or more of the vibration generators are disposed in each region on the film where a polarity of bending moment differs.

Droplet forming device, droplet forming method, and dispensing apparatus

Provided is a liquid droplet forming device including: a liquid container capable of containing a liquid; a membranous member disposed at a bottom of the liquid container and including a discharging hole; a deforming unit capable of deforming the membranous member; and a driving unit configured to drive the deforming unit by outputting a discharging signal for deforming the membranous member to discharge the liquid or a suppressing signal for suppressing residual vibration of the membranous member, wherein the suppressing signal is a signal based on natural vibration period Tof the membranous member, wherein an amplitude of the suppressing signal is lower than or equal to an amplitude of the discharging signal, and wherein interval time Tfrom when outputting of the discharging signal is ended until when outputting of the suppressing signal is started satisfies a formula: T=(m&#x2212;)&#xd7;T, where m represents a positive integer.

Liquid droplet forming device and liquid droplet forming method

A particle counting apparatus is provided that includes: a droplet discharger configured to discharge a droplet containing at least one luminescent particle capable of emitting light upon receiving light; a light irradiator configured to irradiate the droplet discharged by the droplet discharger with light; at least one light receiver configured to receive light emitted by the at least one luminescent particle irradiated with the light emitted by the light irradiator; and circuitry configured to count luminescent particles contained in the droplet based on the light received by the at least one light receiver, the circuitry being configured to measure a presence or absence of the luminescent particles contained in the droplet; and to measure a number of the luminescent particles contained in the droplet.
