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.

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.

clinostat clock type
A clinostat clock is a type of clock that incorporates a clinostat mechanism. A clinostat is a device used in scientific research to eliminate the effects of gravity on biological specimens by continuously rotating them. In the context of a clock, a clinostat mechanism is integrated to keep the clock in constant motion, typically rotating in multiple axes, which can make it difficult for a person to read the time directly. The purpose of such a clock is often artistic or conceptual, challenging traditional notions of timekeeping and perception.

Kipps Apparatus Glass
A Kipp’s apparatus is a laboratory apparatus used to produce small volumes of gases by the reaction of a liquid with a solid, producing gas through bubbling. It consists of three main parts: a reaction vessel, a delivery tube, and a collection vessel. The reaction vessel typically contains a solid reactant at the bottom and a liquid reactant above it, separated by a movable plug or stopcock. As the liquid reacts with the solid, gas is produced and collected in the collection vessel via the delivery tube.
Glass is commonly used to construct Kipp’s apparatus because it is transparent, chemically resistant, and allows for easy observation of the reaction and gas collection. Borosilicate glass, known for its resistance to thermal shock and chemical corrosion, is often the preferred material for constructing Kipp’s apparatus due to its durability and safety in handling reactive chemicals.

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.
