Bubbler
A bubbler, also known as a gas washer or Drechsel flask, is a piece of borosilicate glass laboratory equipment designed for washing or drying gases.
Its main features are:
Material: Made of borosilicate glass, it offers excellent resistance to thermal shock and chemical agents.
Design: It consists of a main flask with a standard ground joint, equipped with two glass tubes. One of the tubes immerses the washing liquid, while the other serves as an outlet for the treated gas.
Use: It is used to bubble a gas through a liquid to purify, dry, or react it.
Capacities: Available in various capacities, such as 100 ml, 250 ml, 500 ml, or 1000 ml, depending on the experimental needs.
Buchner funnel
A glass Buchner funnel.
Here are its main features:
Material: Made of borosilicate glass, offering high chemical and thermal resistance.
Filter disc: Incorporates a sintered glass disc (or “frit”) instead of a filter paper holder, making it useful when conventional filter papers are attacked by reagents (acids or alkalis).
Vacuum connection: Has a side tube with a connection for a vacuum source (often a water pump) to speed filtration.
Ground joint: Equipped with a ground glass cone, allowing a tight connection to other laboratory glassware such as a vacuum flask.
Use: Mainly used for vacuum filtration in the laboratory, particularly for the separation of solids and liquids.
Buie Probe
Buie probe. Its main characteristics are:
Name: Buie Probe
Dimensions: 6.5 inches (approximately 16 cm)
Model Reference: BS 0472-16
Bunion Corrector
Bunion correctors, like the one pictured, offer several key features aimed at correcting big toe alignment and relieving pain:
Adjustable Design: They often feature adjustable straps, Velcro closures, or precise adjustment mechanisms to accommodate different foot sizes and allow for personalized control of the correction angle and pressure.
Comfortable and Breathable Materials: Made from soft, breathable, medical-grade fabrics to ensure maximum comfort during extended use, day or night.
Realignment Support: Often incorporate an aluminum splint or silicone tendon to help straighten the big toe and maintain it in a more natural position, thus reducing the hallux valgus deformity.
Pain Relief: By realigning the big toe and reducing pressure on the bunion, they help relieve the pain and discomfort associated with this condition.
Versatile Use: Some models are designed to be worn during the day, even with shoes, while others are optimized for nighttime use, applying gentle corrective force while you sleep.
Durability and Ease of Use: Designed to be sturdy and easy to put on and take off, ensuring practical everyday use.
Bunsen Burner
The Bunsen burner is a laboratory burner commonly used for heating, sterilizing, or burning substances.
Its main characteristics are as follows:
Components: It consists of a stable base, a gas inlet (with a control valve), a vertical tube (chimney), and a movable ferrule at the base of the tube that controls the air supply.
How it works: It mixes combustible gas (town gas, butane, propane) with air to produce an open flame. The ferrule regulates the air supply, thus influencing the intensity and temperature of the flame.
Types of Flames: By adjusting the air supply, different flames can be obtained, ranging from a cool, yellow flame (incomplete combustion) to a hot, blue, and almost invisible flame (complete combustion).
Temperature: The flame temperature can vary considerably depending on the air setting, reaching high temperatures (e.g., 750 to 1600°C).
Use: It is essential in chemistry and biology laboratories for various applications, including heating reagents, sterilizing instruments, and creating a sterile area for delicate manipulations such as mushroom cultivation.
Burette 10ml
Laboratory burettes are glassware instruments used for the precise measurement of liquid volumes.
Here is some information for purchasing burettes:
- Burettes are graduated glass tubes made of borosilicate glass such as Pyrex, known for their resistance to thermal shock.
- They are used to deliver a precise volume of liquid, particularly during chemical titrations.
- Capacity: 10 ml, with glass or PTFE stopcocks.
Burette 25ml
Laboratory burettes are glassware instruments used for the precise measurement of liquid volumes.
Here is some information for purchasing burettes:
- Burettes are graduated glass tubes made of borosilicate glass such as Pyrex, known for their resistance to thermal shock.
- They are used to deliver a precise volume of liquid, particularly during chemical titrations.
- Capacity: 25 ml, with glass or PTFE stopcocks.
Burette Stand
The burette stand features the following:
Materials:
Made of high-quality aluminum alloy or plastic for the clamp, and metal (such as iron or aluminum) for the stem and base, providing durability and corrosion resistance.
Functionality:
Designed to securely hold burettes during laboratory titration experiments, particularly on a titration table.
Clamp Design:
The clamp is often a “butterfly” or “double” type, allowing two burettes to be held simultaneously. Its jaws have sufficient elasticity to hold the burettes securely without obscuring the graduations.
Stability:
The heavy base and sturdy stem ensure stability during laboratory manipulations.
Use:
Easy to use for securing and adjusting the position of burettes, making it an essential accessory for science laboratories, schools, and factories.
