Abstract
The utility model discloses a molecular hybridization instrument, which belongs to a gene analytic instrument. The utility model comprises a heating unit, a thermostatic chamber (1) and a hybridization container frame (5) capable of doing reciprocating movement. The utility model adopts a microcomputer to control temperature, time and the relative movement rate between reaction liquid and objects. The heating unit is arranged between the thermostatic chamber (1) and an outer shell (7) of the hybridization instrument, and the chamber wall of the (1) is provided with an air channel (2). The utility model has the advantages that air circulation is enlarged, temperature control precision of the thermostatic chamber (1) is increased, and hybridisation efficiency and work safety are enhanced.
Description
Technical field
The utility model relates to a kind of molecular hybridization reaction kit that can be applicable to field of molecular biotechnology, belongs to the genetic analysis instrument class.
Background technology
The reaction of existing molecular hybridization is carried out usually in the following way: (1) will have biomacromolecule DNA, RNA and protein and be sealed in the common plastics bag and be placed in the water bath with thermostatic control again; (2) utilize hybridization container frame that a temperature platform that can heat and being furnished with can move reciprocatingly, by the speed of relative movement between temperature, time and reaction solution in the minicomputer control reaction, the thing, thereby make gene diaphragm and chip, carry out hybridization between the nucleic acid molecule on the micropore automatically.Carry out hybridization in the common plastics bag, often the breakage because of plastics bag causes the reaction liquid leakage to pollute; Though and the latter has avoided the former defective, exist thermostatic chamber working temperature non-uniform phenomenon.
Summary of the invention
The utility model provides a kind of good constant-temperature effect, Hybridization Oven that safety performance is high.
The utility model is achieved by the following technical solution, a kind of Hybridization Oven, comprise a heating unit, with the thermostatic chamber that has temperature sensor, hybridization container frame by the to-and-fro movement unit drives places in the thermostatic chamber, one is carried out closed-loop control by the temperature interface circuit to the working order of heating unit by minicomputer, by the motion interface circuit unitary heating temperature control of to-and-fro movement and working order are controlled again, all can be shown in the temperature in each stage of experiment and the actual value of rotating speed by digital indicator, occur overtemperature in the cut-and-try work and be provided with the buzzer warning function, its key is that described heating unit is arranged between thermostatic chamber and the hybridization instrument shell, and described thermostatic chamber locular wall is provided with the air channel.
Described heating unit is made up of electrothermal tube or nichrome wire and cross flow fan.
Leave the space between the top of described thermostatic chamber and hybridization instrument shell, the bottom, thermostatic chamber top and bottom chamber wall are provided with the air channel.
Described thermostatic chamber is provided with stay-warm case.
Heating unit of the present utility model is arranged between constant temperature working spaces and the Hybridization Oven shell, utilize and run principle on the warm air, adopt cross flow fan, on the constant temperature locular wall, design the air channel, make the air in the thermostatic chamber add systemic circulation, thereby make room temp even, temperature control is accurate, effectively raise crossbreeding effect, also improved the security of products energy simultaneously.
