A laboratory sample/specimen temperature control device, specifically a metal bead bath that has its metal bead temperature controlled by a continuous flow of air into the bed of beads that is heated or cooled by a Peltier device that the air flows over. This provides great thermal uniformity across the bed of beads and constantly monitors and regulates the heat or cooling input rather than utilizing an on/off modulation temperature input approach.

Systems and methods for controlling the temperature of items such as a sample in a vessel or a specimen, in a thermal bath using thermally efficient pellets as the thermal media. The pellets are typically oblong metallic or oblong metallic-coated pellets with rounded edges, a hardened surface, a smooth polished finish, and characteristics that enable efficient thermal communication between the bath's thermal source, the pellets, and the items that are inserted into the mass of pellets. Further, the pellets are dry and moisture and gas impermeable, and they resist microbial growth and are readily decontaminated by several methods including applying an antimicrobial compound to the pellets. The thermal source is controlled to achieve the desired temperature of the items inserted into the pellets.

A system and apparatus for precision temperature control of thermal bead baths used in biological laboratories to heat biological samples is disclosed. The system has an insulated outer shell and an inner shell sealed together to form a recirculation pathway. The inner shell has an air extraction port opening into the recirculation pathway and at least one air injection port opening into the recirculation pathway. A fan is in the recirculation pathway and is positioned to draw air through the air extraction port. At least one thermal sensor is connected to a control and is disposed in close proximity to one of the air injection ports. Beads used in thermal bead baths are placed in a mesh basket inside the inner shell. The fan draws air from the inner shell through the beads and into the recirculation pathway, where the air is heated by a thermal element. The air flows past the thermal element and through the air injection ports back into the inner shell.

A gene sequencing reaction device, a gene sequencing system and a gene sequencing reaction method. The gene sequencing reaction device includes: a supporting platform; a dipping container disposed on the supporting platform, wherein the dipping container has a dipping reaction area, and the dipping reaction area is configured to hold a chemical reagent for gene sequencing reaction, so as to dip a sequencing chip having a DNA sample loading structure on the surface and having a DNA sample loaded thereon in the chemical reagent to perform a gene sequencing reaction; a temperature control apparatus, configured to control the temperature of the chemical reagent in the dipping reaction area; and a transfer apparatus, configured to insert the sequencing chip into the dipping reaction area or pull out the sequencing chip from the dipping reaction area.

A recirculating bath includes a reservoir for receiving a working liquid, a recirculating pump, and at least one thermal element. The recirculating pump and thermal element are located externally to the reservoir so that the reservoir has an unobstructed working space. The thermal element may be thermally coupled to the working liquid through an interior surface of the reservoir, or the working liquid may be circulated over the thermal element by the recirculating pump in a chamber external to the reservoir. The recirculating bath may also include a lid that provides access to the reservoir by pivoting on a latching hinge. When open, the lid may provide a working surface adjacent to the reservoir. The lid may also include a selector that unlatches the hinge so that the lid can be removed. The recirculating pump may be fluidically coupled to the reservoir via a manifold.

To suppress generation of dew condensation in temperature control space when heating temperature control is performed. In an apparatus, an air temperature control part for cooling or heating air in temperature control space has a first temperature control element for performing at least cooling of air, and a second temperature control element for performing at least heating of air downstream of the first temperature control element. In this manner, when heating temperature control is performed, cooling and dehumidification of air taken in from an air intake portion can be performed by the first temperature control element, and then heating of the dehumidified air can be performed by the second temperature control element.

It is necessary to dispose a plurality of units which have different target temperatures on an apparatus in a more integrated state in order to improve analysis performance and processing capacity per unit space of the apparatus. Therefore, it is necessary to mitigate influence of temperature exerted between units. It is possible to reduce the temperature influence exerted between the units and thus efficiently control temperature by properly disposing the units in the apparatus, based on the relationship between a use environment temperature of the apparatus and a target temperature of each unit and temperature accuracy required for the unit.
