, Description:Invention Description
When atoms or molecules approach very close to one another and collide results in to new bond formation. The higher the speed at which these molecules are travelling, the more frequent and effective collisions between these species occur. According to Arrhenius equation, increasing the temperature by 10 K will roughly double the pace of a reaction. That means at the higher temperature, reaction is completed much faster.
However, in some cases it is desirable to carry out reactions at low temperatures, in spite of the lowering effect on the rate of the reaction. Chemists use cooling baths to maintain a specific temperature or temperature range when running a reaction below room temperature. By immersing the reaction flask in a suitable cooling bath, reactions can be cooled to the desired temperature. The reaction's reagents are never in direct touch with the cooling bath's chemicals. A single cryogenic (cooling) component (such as ice, dry ice, or liquid nitrogen) or a mixture of the cryogenic component with a solvent and/or an additional salt can make up the cooling bath.
The solvent effectively brings the cooling agent's temperature to the reaction flask, while additive decreases the mixture's freezing point.
Traditional Cooling Bath Setup
For a general set-up, prepare the cooling bath in an insulated dewar flask and immerse the reaction flask into the bath. Doing so also prevents ice buildup on the exterior of a non-insulated bath, such as a crystallizing dish or beaker, caused by condensation and freezing of water vapor from the air.

Typical ice bath assembly
Types:
The simplest and cheapest cooling bath is an ice/water mixture, which maintains a temperature of 0 °C. For lower temperatures, there are three main types of cooling baths:
1. Ice: slurry of ice, and an inorganic salt such as sodium chloride or calcium chloride. Can reach temperatures down to about -40 °C. The temperature depends on the amount and type of salt used, based on the freezing point depression effect.
2. Dry ice : A slurry of dry ice and an organic solvent. Can reach temperatures down to about -78 °C.
3. Liquid nitrogen: Liquid nitrogen, either used as-is, or with an organic solvent. Can reach temperatures down to about the boiling point of pure N2, -196 °C. The temperature depends on the freezing point of the organic solvent.
Liquid nitrogen is usually considered the best cooling bath refrigerant because it is non-toxic, is cheap, and leaves no residue. However, it suffers from the drawback of being cold enough to condense liquid oxygen from the air. This is important when the cooling bath is used for a cold trap, where solvents and oxygen may accumulate to give a potentially explosive mixture.
The difficulty of bringing tiny amounts of a substance to a given temperature and keeping it at that temperature for a certain period of time is often faced in biochemical, biological, or genetic labs. Devices for this purpose are well-known and commercially available. Liquid baths, particularly thermostat-controlled water baths, are well-known equipment. They typically comprise of a vessel with an electric heating device, a stirrer, and, in certain cases, a circulating pump, usually with a capacity of several litres. A thermostat may be used to regulate the heating equipment so that the temperature of the circulating liquid is maintained at a set temperature.
The purpose of this invention is to provide a laboratory equipment that is specifically designed to meet the demands of biological, biochemical, or genetic laboratories. It is simple to use for cooling samples of liquids or biological material, as well as guiding them through temperature cycles, and it requires minimal space and energy. It was designed specifically to complete cycles with temperatures that are partly below room temperature. It's simple to sanitise and keep sanitary. It can be outfitted with the appropriate stirring equipment.

DESCRIPTION OF THE PREFERRED APPRATUS
WORKING OF APPARTUS
Referring to Figure I and II the numeral 5 represent thermoelectric cooling modules, converts electricity in form of cooling. The cooling is transferred to working area 9, through copper plates/ jacket 2.
These copper plates are surrounded and guarded by heat insulators 3, which prevent loss of temperature during process. The cooling carried forwarded by 2 is applied to working area 9 and further it is distributed to synthetic apparatus via aluminum beads 1. The instrument can be used without 1 if other solvent is used.
Some reactions required cooling with stirring; In order to implement stirring- magnetic stirrer 4 is assembled above 5. It is controlled by magnetic stirrer regulator 7, which is located on front surface at lower left hand corner. The zero position of 7 indicates, instrument is working without stirrer.
The desired temperature is controlled and adjusts by temperature controller 6 with its digital display. Complete instrumental operation can be stopped or start through main switch 8.

PATENT APPLICATION WORKSHEET

1. Briefly describe the problem that you were trying to solve?
Availability of cooling reagent or amount of ice is always main problem before starting of cooling experiment. Many times sudden cooling required but due to unavailability of ice (or other cooling reagents) it is not executed properly. Once assembly starts, it takes much time to attain desired temperature. Many time the material from reaction flask is contaminated with cooling solvent used, that may spoil the reaction, or even capable of altering the desired product.
In traditional ice bath, temperature is fluctuated and depends on nature of cooling agent. Constant temperature is difficult to maintain with traditional assemblies.
In many reactions simultaneous stirring and cooling is needed.

2. What solutions were used to solve this problem in the past?
The time it takes to set up and reach a steady temperature was previously included in the reaction work up time.
Every time a fresh reaction setup was performed, previously used cooling reagents were discarded.
Reduced temperature can be accomplished by adding salts to ice.
