Conical flask
A conical flask, also known as an Erlenmeyer flask, is a type of laboratory glassware commonly used in chemistry laboratories for holding, mixing, and heating liquids. It has a conical shape with a flat bottom, a cylindrical neck, and a narrow opening. The conical shape allows for easy swirling and mixing of liquids without splashing, and the narrow neck minimizes evaporation and allows for the attachment of various laboratory apparatus such as stoppers, funnels, or tubing. Conical flasks are typically made of borosilicate glass, which is resistant to thermal shock and chemical corrosion. They come in various sizes, ranging from small volumes for experiments to larger sizes for industrial applications.

conductivity rods
Conductivity rods, also known as conductivity probes or conductivity sensors, are instruments used to measure the ability of a solution to conduct electrical current. They are commonly used in various fields such as chemistry, environmental science, and water quality monitoring.
These rods typically consist of two electrodes that are immersed in the solution being tested. An electrical current is passed between these electrodes, and the conductivity of the solution is determined by measuring the resistance to the flow of current.
The conductivity of a solution depends on factors such as the concentration of ions present in the solution and the temperature. Therefore, conductivity rods often come with built-in temperature compensation to provide accurate readings over a range of temperatures.
Conductivity rods are valuable tools for assessing the purity of water, determining the concentration of dissolved salts or other substances in a solution, and monitoring the overall quality of aqueous solutions in various industrial processes. They are relatively simple to use and provide quick and reliable measurements, making them indispensable in many laboratory and field settings.

complete kymograph equipment
A complete kymograph equipment typically includes:
- Kymograph Drum: The central component, usually made of metal or plastic, which rotates at a constant speed. It has a surface where paper or film can be attached for recording physiological data.
- Clockwork Mechanism: This regulates the rotation of the drum at a constant speed. Modern versions may use electric motors for rotation.
- Recording Mechanism: It could be a stylus or pen attached to a lever arm, which translates physiological changes into a graphical representation on the rotating drum. Alternatively, modern kymographs may use digital sensors for data acquisition.
- Mounting Stand: A stable platform to support the kymograph apparatus.
- Pulley System: This connects the drum to the clockwork mechanism, ensuring smooth and consistent rotation.
- Paper or Film: The recording surface where physiological events are transcribed. It may be attached to the drum using clips or adhesives.
- Ink or Pen: If using a stylus, ink or pen is required to make marks on the recording surface.
- Adjustment Controls: These allow fine-tuning of the drum’s rotation speed and the sensitivity of the recording mechanism.
- Light Source: In some setups, a light source is positioned to enhance visibility of the recorded data, especially in dark environments.
- Supporting Software or Analysis Tools: For modern digital kymographs, software may be needed to analyze the recorded data.
- Optional Accessories: These may include additional sensors for measuring specific physiological parameters, such as temperature, pressure, or electrical signals.

LABORATORY EQUIPMENT
combustion tube
A combustion tube is a laboratory glassware used primarily in organic chemistry for conducting combustion reactions. It’s a straight, narrow tube made of heat-resistant glass, usually borosilicate glass, with one end sealed.
Here’s how it typically works:
- Preparation: The sample to be combusted is usually placed inside the combustion tube. This sample is often an organic compound or a mixture of compounds.
- Sealing: After loading the sample, the open end of the tube is sealed, often using a stopper or a glass rod. This ensures that the combustion reaction takes place within a closed system.
- Combustion: The sealed tube is then placed in a combustion furnace, which raises the temperature to a level where combustion of the sample occurs. This typically involves heating the sample in the presence of excess oxygen.
- Collection of Products: As the sample combusts, it reacts with oxygen to produce carbon dioxide and water vapor, along with other possible products depending on the composition of the sample. These products are collected and can be analyzed using various techniques such as gas chromatography.
- Analysis: The collected products can provide valuable information about the composition of the original sample. For example, the amount of carbon dioxide produced can be used to determine the carbon content of the sample, which is useful in determining its molecular formula or identifying functional groups present in organic molecules.

Banana plug
A banana plug is a type of electrical connector commonly used in audio and electronic devices. It is designed to securely connect wires to binding posts or jacks found on audio equipment, speakers, amplifiers, and test instruments.
The name “banana plug” comes from its distinctive shape, resembling a curved banana. These plugs typically have a cylindrical metal body with a spring-loaded prong or pin that can be inserted into a corresponding socket or binding post. The plug’s design allows for easy and quick connection and disconnection of wires without the need for soldering, making it a convenient choice for frequently changing connections.
Banana plugs are favored for their reliable contact and low resistance, which helps maintain good audio signal quality. They are commonly used in home audio setups, speaker systems, and test and measurement applications where a secure and durable electrical connection is essential.

Folin Ciocalteus Phenol Reagent 2.5l
Folin Ciocalteus phenol reagent is a chemical solution commonly used in analytical chemistry to determine the concentration of phenolic compounds, particularly in plant extracts and food samples. The reagent is named after its developers, Otto Folin and Vintilă Ciocâlteu.
The Folin-Ciocalteu reagent consists of a mixture of phosphomolybdic and phosphotungstic acids in a highly alkaline solution (usually sodium carbonate or sodium hydroxide). When this reagent comes into contact with phenolic compounds, such as polyphenols, flavonoids, and other aromatic compounds, a blue-colored complex forms due to a reduction of the phosphomolybdic-phosphotungstic acid mixture by the phenols. The intensity of the blue color is proportional to the concentration of phenolic compounds in the sample.
This reagent is widely used for the quantification of total phenolic content in various biological and food samples, making it an essential tool in antioxidant and phytochemical research. The Folin-Ciocalteu assay is a reliable and well-established method for assessing the antioxidant capacity of samples and has been utilized in numerous scientific studies and analytical applications.
