創造化学研究所 List of Products and Services

The small mechanical stirrer STR-L1000 is a clip-on type mechanical stirrer that can be directly installed on the tapered neck of a flask. It offers higher torque than the ultra-compact type (STR-S300) and can accommodate commercially available stirring rods with a shaft diameter of 8mm. A controller type that displays the rotation speed is also available. Features: 1. Clip-on design allows direct attachment to the tapered neck of a flask (standard 29/42; custom options available) 2. Compact and lightweight for easy handling 3. Compatible with stirring rods with a shaft diameter of 8mmΦ 4. High torque (0.16N·m / 300rpm) capable of stirring high-viscosity liquids 5. Rotation speed display type also available 6. Custom options available (torque increase, shaft diameter changes, acid gas compatibility, multi-channel controllers, etc.)

• Mixer/Stirrer

Easily blocks light diffusion just by covering the reaction container Ensures safety when using ultraviolet (UV-LED) - The protective glass of the light source unit can be easily replaced No hassle of cleaning dirt or adhering substances

• Ultraviolet irradiation equipment
• LED Module

The aluminum cup can be efficiently heated and evaporated in the n-hexane extraction test. Additionally, the evaporated hexane can be recovered and reused. By processing in a closed system using our patented technology, there is no contamination, contributing to accurate analysis. The evaporation and recovery sections are modularized, allowing for greater flexibility in installation locations.

• Water quality testing

Traditionally, vacuum seals, shafts, and motors were installed individually, leading to the rapid wear of expensive Teflon shafts and seals, and the installation was difficult due to the large and heavy motors. In this product, the integration of the vacuum seal, motor, and shaft allows for one-touch fixing, and commercially available 1m Teflon rods can be cut to the required length for use.

• Stirrer

By evaporating the solvent in a sealed atmospheric pressure system and recovering it through cooling and liquefaction, there is no external release of the solvent. Additionally, unlike conventional methods, it does not intake external air during drying, thus avoiding unnecessary heat consumption.

• Thermostatic water bath
• Cooling system
• Chiller

■ Operation remains unchanged from before ■ One-fourth the size of the previous version

• Concentration Equipment

The organic solvent vapor from the exhaust of the vacuum pump is condensed through low-temperature cooling by a refrigeration unit, and any remaining trace amounts of solvent vapor are captured by activated carbon, thereby minimizing the atmospheric release of the solvent to the greatest extent possible.

• Other physicochemical equipment

■Features of EcoClear No condensation in the condenser section No cooling water circulation system required No insulation hose required Compact slim design (width 225mm) Significant space-saving as a whole system (installation area is less than 2/3 of conventional systems) Recovery rate under reduced pressure with organic solvents is over 95% Achieves energy savings compared to cooling water circulation systems Compatible with coil-type, simple-type, and jura-type evaporators

• Other physicochemical equipment

The cooling of the organic solvent recovery section of the rotary evaporator, cooling of measuring instruments, feed, low-temperature reaction baths, etc., can be widely utilized.

• Thermostatic water bath
