Description
Technical Parameters
The mini conical flask, also known as the triangular flask, Eisenberg flask, conical flask or Elenmeyer flask, is a common glassware in chemical laboratories. It was invented by the German chemist Richard Erlenmeyer in 1861 and was named for its unique conical design. This design enables the flask to remain stable during oscillation, while facilitating the thorough mixing of reactants and preventing the splashing of liquids. It can be used in precipitation reactions, biological cultures, hydrolysis reactions, REDOX reactions, complexation reactions, esterification reactions, dissolution experiments, acid-base mixing reactions, ion testing experiments, decomposition reactions, gas absorption experiments, colloid preparation experiments, precipitation transformation experiments, salt hydrolysis equilibrium shift experiments, coordination equilibrium experiments, and REDOX titration experiments, etc.
Specifications
Application in specific experiments
To further illustrate the versatility of the bottle, let's examine its application in a few specific experiments.
|
● Experiment 1: Synthesis of an Organic Compound In an experiment to synthesize a specific organic compound, the researchers used a 100 ml flask as a reaction vessel. The reactants were dissolved in a suitable solvent and mixed using a magnetic stirrer. The flask was then heated to reflux using a heating mantle, and the reaction was monitored using a thermometer inserted into the flask. After several hours, the reaction mixture was cooled, and the product was isolated and purified using standard techniques. The bottle has the characteristics of uniform heat dissipation and high temperature resistance, which is the ideal choice for this experiment. ● Experiment 2: Cultivation of Microorganisms In experiments to grow a particular strain, the researchers used a 250 ml mini conical flask as a culture container. The flask is filled with a sterile growth medium and a bacterial sample is inoculated into the medium. The flask is then sealed with a screw cap and incubated at a constant temperature. Over the course of a few days, the bacteria grow and multiply in the flask, forming a visible colony. The bottle's wide body and secure neck provide an ideal environment for bacterial growth, while also facilitating observation of colonies. ● Experiment 3: Extraction of a Natural Product In an experiment to extract natural products from plant material, the researchers used a 50 ml mini conical flask. Place the plant material in a flask and add a suitable solvent to extract the desired compounds. The flask is then gently heated to facilitate the extraction process. After a few hours, the solvent is removed with a rotary evaporator, leaving the extracted compound. The vial's small size and ability to withstand heat made it suitable for this experiment, allowing the researchers to extract it efficiently and with minimal waste. |

● Leakage Problems
Leakage from this flask can be a significant problem, especially when dealing with hazardous chemicals or sensitive reactions.The primary cause of leakage is often a faulty or worn-out gasket or seal. To address this problem:
1) Inspect Regularly: Regularly inspect the gasket and the sealing surface for any signs of wear, tear, or debris.
2) Replace Gaskets: Replace worn-out gaskets promptly with genuine replacements to ensure a tight seal.
3) Proper Closure: Ensure that the flask is closed properly and securely before shaking or transporting it.
Additionally, using excessive force to close the flask can damage the gasket or the threading of the lid, leading to leakage. Therefore, always apply moderate pressure when closing the flask.
● Scaling Issues
Scaling, or the buildup of precipitate or residue on the inner walls of the flask, can interfere with accurate measurements and reactions. Scaling can occur due to the precipitation of reactants, evaporation of solvents, or the formation of reaction products. To address scaling issues:
1) Use Distilled Water: When diluting solutions or rinsing flasks, use distilled water to minimize the formation of precipitates.
2) Avoid Evaporation: Keep the flask covered when not in use to prevent evaporation and the subsequent concentration of solutes.
3) Regular Cleaning: Clean the flask regularly using appropriate cleaning agents to remove any buildup of residue.
In some cases, the use of specialized cleaning solutions or ultrasonic cleaners may be necessary to effectively remove stubborn residue.

How to perform cooling operation
Preparation before cooling operation
► Wash and dry
Purpose: To remove dirt and possible residual substances on the surface of the conical bottle to avoid contamination or error.
Steps:
Use detergent or special laboratory cleaner to thoroughly clean the inside and outside walls of the conical bottle.
Rinse the conical bottle with distilled or deionized water, making sure all cleaning agents are rinsed out.
Place the conical bottle in the oven to dry, or use a clean cloth to dry, and then place in the dryer for use.
► Select the appropriate cooling medium
Considerations: experimental requirements, liquid properties, cooling speed, safety, etc.
Common cooling media: ice-water mixture, ice-salt mixture, cooling circulating water, liquid nitrogen (for very low temperature requirements), etc.
► Preparation of cooling device
Check: Ensure that the cooling device (such as cooling tank, cooling circulation system, etc.) is intact and operating normally.
Preheating or precooling: According to the experimental requirements, the cooling device is preheated or precooled.
Cooling operation steps
Place the mini conical bottle in the cooling medium
Controls:
Carefully place the mini conical bottle containing the sample into the cooling medium.
Ensure that the conical bottle is fully immersed in the cooling medium for the best cooling effect.
Control cooling speed
Importance: Too fast a cooling rate may cause the conical bottle to break or the sample properties to change.
How:
The cooling speed is controlled by adjusting the temperature or flow of the cooling medium.
Use a thermometer to monitor the temperature of the cooling medium to ensure that it is within a safe range.
Stir and shake (if needed)
Objective: To promote heat transfer and speed up cooling.
Controls:
Use a magnetic stirrer or manually shake the conical bottle, but pay attention to the force and frequency to avoid sample spatter or the conical bottle cracking.
Stirring or shaking should be uniform and slow to avoid excessive thermal stress.
Monitor temperature changes
Objective: To ensure that the sample is cooled within a safe temperature range.
How:
Use a thermometer or thermocouple to monitor the temperature change of the sample in the conical bottle.
Record temperature change data for subsequent analysis and processing.
The treatment after cooling
Remove the conical bottle
Operation: When the sample has cooled to the desired temperature, carefully remove the conical bottle from the cooling medium.
Note: Avoid sudden temperature changes, so as not to crack the conical bottle or change the properties of the sample.

Make sure the conical bottle material can withstand the required cooling temperature.
Avoid excessive force when using magnetic stirrers or manual shaking.
2) Sample contamination:
Ensure that conical bottles and cooling media are thoroughly cleaned and dried before use.
Avoid contact between samples and external environment during processing.
3) Uneven cooling:
Check whether the cooling device is operating normally and whether the cooling medium is evenly distributed.
Use a magnetic stirrer or manual shaking to promote heat transfer.
