Flask, round bottom and flat bottom, with a joint.
This is a round-bottom and flat-bottom flask made of Pyrex glass with a common joint. In addition to standard joint sizes such as 15/25, 24/30, and 29/32, we can also manufacture it in your specified joint size, so please contact us.
Separable flask, cylindrical round type
This is a glass separable flask (reaction vessel) in a cylindrical round shape, widely used for analysis and research.
Separable flask, bottle type
It is a glass separable flask (reaction vessel) widely used for analysis and research.
Separatable flask, round type
It is a glass round separable flask (reaction vessel) widely used for analysis and research.
The mouth is designed with a durable, thick rim. The slender neck minimizes splashing of the contents and is suitable for stirring liquids.
The triangular flask is available in products ranging from 10ml to 5L. H-32: HARIO-32 is a borosilicate glass with a low expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, exhibiting excellent chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, or cadmium, nor does it use sulfurous acid or antimony, which are typically used as bubble agents in regular glass. Due to its low expansion coefficient, it experiences minimal expansion and contraction from heating and rapid cooling, making it a glass material with high heat resistance that can withstand a temperature shock of 250 degrees.
The mouth is designed with a thick rim that is resistant to cracking. It is a flask that is strong against changes in pressure. The shape makes it easy to pour out the contents and easy to clean.
The flask comes in sizes ranging from 50ml to 3L. "H-32" Hario -32 glass is a low thermal expansion coefficient heat-resistant glass (borosilicate glass -1) that has been perfected through years of research. It meets the standards of "borosilicate glass -1" as specified in JIS R 3503, exhibiting excellent chemical durability and heat resistance, making it an outstanding glass for scientific and industrial use. "H-32" does not contain heavy metals such as lead, zinc, and cadmium, nor does it use arsenic or antimony, which are commonly used as foam-cutting agents. It can be safely used for chemical analysis. 【Features】 ○ Low thermal expansion coefficient heat-resistant glass (borosilicate glass -1) ○ Excellent chemical durability and heat resistance ○ Outstanding glass for scientific and industrial use ○ No heavy metals, arsenic, or antimony used For more details, please contact us or download the catalog.
The mouth is designed with a thick rim that is resistant to cracking. Additionally, its shape promotes the evaporation of contents during heating.
Kjeldahl flasks are available in sizes ranging from 30ml to 500ml. H-32: HARIO-32 is a borosilicate glass with a low expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, offering excellent chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, or cadmium, nor does it use sulfurous acid or antimony, which are typically used as bubble-reducing agents in ordinary glass. Due to its low expansion coefficient, it experiences minimal expansion and contraction from heating and rapid cooling, making it a glass material with high heat resistance that can withstand a temperature shock of 250 degrees.
Common joint flask for rotary use
We offer 12 varieties ranging from 50ml to 1L. Based on the Japanese Industrial Standards (JIS), by machining the inside of the neck of the flask, it can be integrated into machines such as rotary evaporators. The design minimizes axial wobble when the flask is rotated. For more details, please refer to the catalog. We look forward to your inquiries.
Ideal for stirring and storing pharmaceuticals!!
The HARIO triangular flask has the same shape and comes with a stopper, making it suitable for stirring and storing chemicals. It is also compatible with JIS standards. ■ HARIO Glass H-32 This is a borosilicate glass with a low expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, exhibiting excellent chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, or cadmium, nor does it use sulfurous acid or antimony, which are commonly used as foam agents in regular glass. Due to its small expansion coefficient, it experiences minimal expansion and contraction from heating and rapid cooling, making it a glass material with high heat resistance that can withstand a temperature shock of 120 degrees. *Please feel free to contact us for more details.
For pharmaceutical manufacturers! We custom-manufacture products with enlarged mouth openings!
We custom-manufacture "graduated flasks for tablets" for pharmaceutical manufacturers. Are you having trouble with the small neck of graduated flasks with a small capacity (5-25ml)? Have you ever found that the small inner diameter of the neck prevents you from putting tablets into the graduated flask? Generally, it is said that a tablet size of about Φ7-8mm is easy to swallow. We manufacture products with a larger neck as a custom order. 【Features】 ■ Custom manufacturing of products with a larger neck ■ Standard inner diameter: Φ8mm / Custom product inner diameter: Φ11.8mm (minimum part) *For more details, please refer to the PDF document or feel free to contact us.
Directly engraved numbering. For improved management efficiency and to prevent mix-up errors.
Our company, which manufactures glass volumetric flasks and other items, also offers custom "sandblasting numbering processing." We can accommodate not only equipment numbers and dates but also lot number engravings. Numbering contributes to the efficiency of history management and sample management. It helps prevent human errors such as label peeling and mix-ups. 【Features】 ■ A lineup of volumetric flasks, hollow pipettes, etc. ■ Custom direct engraving of equipment numbers using sandblasting ■ Traceability and issuance of internal inspection reports available (for a fee) ■ Established quality management system with ISO 9001 certification *For more details, please refer to the materials. Feel free to contact us with any inquiries.
