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.

Induction coil
An induction coil is an electrical device designed to produce high-voltage pulses from a low-voltage direct current (DC) supply. It typically consists of a primary coil and a secondary coil wound around a common iron core. When current flows through the primary coil, it creates a changing magnetic field, which induces a high voltage in the secondary coil through electromagnetic induction. This high-voltage output can be used for various purposes such as powering spark plugs in internal combustion engines, igniting gas-discharge lamps, or as a component in devices like Tesla coils and induction heaters. Induction coils have been historically significant in the development of telecommunications, early radio technology, and various electrical experiments.

Gold leaf electroscope
A gold leaf electroscope
A gold leaf electroscope is a simple device used to detect the presence and magnitude of electric charge. It consists of a metal rod or plate (usually brass) with a pair of thin gold leaves attached at the top. The rod is usually housed in a glass container to protect it from air currents.
Here’s how it works:
- Charging: When a charged object is brought close to the metal rod or plate, the electric charge induces a redistribution of charge in the metal rod. If the charged object is positively charged, it repels positive charges in the metal rod to the leaves, causing them to acquire a positive charge and repel each other. Similarly, if the charged object is negatively charged, it induces a negative charge in the metal rod, causing the leaves to acquire a negative charge and repel each other.
- Detection: The repulsion between the leaves causes them to diverge away from each other. The degree of divergence depends on the magnitude of the electric charge present. A stronger charge will cause the leaves to diverge further.
- Neutralization: If the charged object is removed, the leaves may remain diverged for some time if the electroscope is insulated from its surroundings. However, over time, any charge present on the leaves will dissipate due to the conductivity of the air and the surroundings, causing the leaves to return to their original position.

FOOD & PHARMACEUTICALS PROCESSING CHEMICALS
Aspartame 25kg
Aspartame is a low-calorie artificial sweetener that is widely used as a sugar substitute in various food and beverage products. It is a non-saccharide sweetener, meaning it does not belong to the family of natural sugars like sucrose or fructose. Aspartame is composed of two amino acids, phenylalanine and aspartic acid, linked together with a methyl ester bond.
This sweetener is known for its intense sweetness, being approximately 200 times sweeter than sugar, which allows for its use in very small quantities to achieve the desired level of sweetness in food and drinks. Aspartame has gained popularity as an alternative to sugar due to its minimal impact on caloric intake, making it suitable for individuals aiming to reduce their sugar consumption or manage their weight.
Upon ingestion, aspartame is broken down into its component amino acids and a small amount of methanol, which is further metabolized into formaldehyde and formic acid. However, the quantities produced are well within the range deemed safe by regulatory authorities, and the body’s natural metabolic processes handle them efficiently.

Knife switch
A knife switch, also known as a switchblade switch or simply a blade switch, is a type of electrical switch characterized by a hinged lever that resembles a knife blade. It’s commonly used in electrical circuits to manually interrupt or connect the flow of current. The blade of the switch is typically made of metal and is connected to a conductive component of the circuit. When the blade is moved to one side, it makes contact with another conductive element, completing the circuit. Conversely, moving the blade to the other side breaks the connection, interrupting the flow of electricity. Knife switches were once commonly used in electrical systems, but they have largely been replaced by more modern switches in most applications. However, they still hold significance in certain contexts, such as educational demonstrations and historical exhibits.
