Abstract
The utility model discloses a simple and easy multipurpose procedure cooling box, including cooling box main part, keep warm lid and sample groove, the lid that keeps warm is located the top of cooling box main part, sample trench in the inside of cooling box main part, the rectangle sample groove and the cylindrical sample groove of depositing the pipe is frozen including being used for depositing different models in the sample groove, the cooperation through thread sealing is covered with keeping warm to cooling box main part. The utility model discloses not only can be used for freezing save of summary procedure unicellular or that organize the type, can also satisfy great volume cell suspension's cooling and preserve and the multiple freezing needs of preserving container procedure cooling simultaneously. The thread sealing cooperation is covered in cooling box main part and heat preservation, more helps keeping the stability of cooling box, prevents box body and interior slotware's liquid outflow.
Description
Technical field
The utility model relates to a kind of program temperature reduction box, particularly a kind of Simple multipurpose program temperature reduction box.
Background technology
The freezen protective of cell needs to add suitable cryoprotector, forms ice crystal to prevent the water in temperature-fall period in cell and in environment.Do not add cryoprotector and can cause a series of change in cell, the cellular damage caused as mechanical damage, electrolyte concentration rising, osmotic pressure change, dehydration, pH value change, protein denaturation etc. is even dead.
The most frequently used preserving type of current biological cells and tissues is Cryopreservation (being stored in-196 ° of C), and temperature-fall period becomes the most critical factor determining preservation effect.What the temperature-fall period of current single celled deep-bed drying mainly adopted is slow cooling mode, can realize slow programmed cooling, to ensure the survival of cell by adopting the programmed cooling instrument of conputer controlled.But due to programmed cooling instrument costly, take up an area large, complex operation is complicated, need the shortcomings such as the timely supply of liquid nitrogen, domestic most researcher generally uses refrigerator to lower the temperature step by step, and summary procedure cooling box is progressively applied to the freezing of biological cells and tissues in recent years.
What summary procedure cooling box adopted is that the organic reagents such as isopropyl alcohol are as buffering, at the cell balanced at 4 DEG C and program temperature reduction box are placed in-80 DEG C, the cooling rate of 1 DEG C/min can be realized, substantially meet the needs of cell deep-bed drying slow cooling, and realize the higher Cell viability of frozen rear cell maintenance.
The frozen concentration of cell is generally 5 × 10
5/ mL is to 1 × 10
7between/mL, the frozen excessive concentration of cell or the too low motility rate that all can reduce frozen rear cell, significantly affect refrigerating effect.Along with carrying out of clinical testing and research etc., to the increase of more cell (even can reach 109) demand, the preservation container of more volume just seems particularly important, and equally, the programmed cooling device that can meet corresponding large volume cell cryopreservation is also extremely urgent.Tube seat shape program temperature reduction box conventional at present is only suitable for the cell cryopreservation tube of specific model, cannot meet the demand.
Summary of the invention
For the defect of prior art, the utility model provides a kind of Simple multipurpose program temperature reduction box, not only may be used for summary procedure stored frozen that is unicellular or organization type, the needs of programmed cooling while of the cooling preservation of larger volume cell suspension and multiple freeze storage container can also be met.
In order to solve the technical problem, the technical solution adopted in the utility model is: a kind of Simple multipurpose program temperature reduction box, comprise cooling box main body, insulation cover and sample slot, insulation cover is positioned at the top of cooling box main body, sample slot is positioned at the inside of cooling box main body, and described sample slot comprises rectangle sample slot for depositing different model cryopreservation tube and cylindrical sample slot; Described cooling box main body and insulation cover pass through threaded sealing fit.
Further, the quantity of described rectangle sample slot is 2-5, and length is 140-180mm, and width is 10-20mm, and the degree of depth is 50-80mm; Described cylindrical sample slot has two profiles number, and a kind of aperture is 10-30mm, and hole depth is 40-60mm, and another kind of aperture is 10-30mm, and hole depth is 30-50mm, and the quantity of cylindrical sample slot is 10-20.
Further, described cooling box main body is combined by thread seal with sample slot.
Further, described cooling box main body is cylindrical.
Further, described cooling box main body, insulation cover and sample slot all use polythene PE material to make.
The beneficial effects of the utility model: Simple multipurpose program temperature reduction box described in the utility model comprises cooling box main body, insulation cover and sample slot, described sample slot comprises rectangle sample slot and cylindrical sample slot, cylindrical sample slot has two profiles number, not only may be used for summary procedure freezen protective that is unicellular or organization type, the needs of programmed cooling while of the cooling preservation of larger volume cell suspension and multiple freeze storage container can also be met.Described cooling box main body and insulation cover threaded sealing fit, more contribute to the stability keeping cooling box, prevent the liquid of box body and interior slotware from flowing out.
