Quantity: 1 piece
This is a funnel made based on the shape of a manhole cover. Consisting of only one hole and groove in the center of the filter surface, it is easy to clean and can be connected to the suction bell by sliding.
Material: Borosilicate glass (JR-1)
Buchner type
[Features & Key Advantages]
● High-quality “Buchner-type Funnel” for Laboratory Experiments
Made of glass (borosilicate) with excellent chemical and heat resistance
Exhibits the reliability and durability required for chemical experiments, which cannot be achieved with everyday plastic funnels. A material widely used for research and analytical purposes.
Convenient size with a φ40mm fritted plate diameter
Compatible with the standard φ40mm filter size, making it highly versatile. Can be used with a wide range of filter papers and filtration apparatus.
Buchner-type design enables powerful filtration
Designed for use with vacuum suction or reduced-pressure filtration, efficiently separating solids from liquids and recovering precipitates (※ Vacuum equipment and suction bottles must be prepared separately).
● Ground Joint TS19/28
International standard ground joint connection
Equipped with a TS19/28 ground joint, ensuring secure connection with suction bells, flasks, and filtration devices of the same standard. Minimizes misalignment and wobbling while ensuring airtightness.
Combines ease of handling with easy cleaning
The clear finish of the joint allows for easy washing and drying after use, reducing post-experiment maintenance.
● Suitable for a wide range of applications
Ideal for research, educational institutions, and quality control
Perfect as a standard laboratory tool for chemical experiments, chemical analysis, food hygiene testing, environmental testing, and more.
Compatible with vacuum filtration, reduced-pressure filtration, and liquid separation
Makes the most of the Buchner-type advantages, improving filtration accuracy and speed in practical settings.
● Designed for long-term use with stable quality
Durability of borosilicate glass
Resistant not only to chemicals but also relatively resistant to thermal shock, capable of handling temperature changes during experiments.
Simple and practical structure
The funnel’s straightforward, no-frills design demonstrates its true value in experimental applications.
[Recommended For]
- Researchers and technicians conducting chemical experiments and analyses
- Educational institutions such as universities and technical schools
- Those seeking reliable filtration results in food, environmental, or medical quality inspections
- Those aiming to improve efficiency in vacuum or reduced-pressure filtration operations
[✍ Summary]
The Tsukiawase Kiriyama Funnel (Buchner-type) φ40mm / TS19/28 is an experimental funnel made of borosilicate glass with excellent chemical and heat resistance.
