HARIO Science Official Online Store OPEN! Heat-resistant glass scientific products

This is a beaker with excellent heat resistance and chemical properties. The flared opening makes it easy to hold and reduces the likelihood of liquid dripping from the spout.

There are products ranging from 10ml to 10L beakers. 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, and cadmium, nor does it use sulfurous acid or antimony, which are commonly used as foam 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.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers. For more details, please refer to the related link.

We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
