• A wide variety of rotary evaporators available
Since the release of the N-1 model evaporator in 1965, EYELA’s rotary evaporator series has been beloved for over 50 years and highly regarded in laboratories in Japan. To support the development of better research environments, we offer a wide range of models.
| Compact condenser suitable for installation in a fume hood |
Condenser suitable for small to large volume flasks | Condenser suitable for low to high boiling point substances |
| Evaporator (driving unit) + Type E condenser (vertical double spiral, adapter integrated) + Water bath | Evaporator (driving unit) + Type V condenser (vertical double spiral) + Water bath | Evaporator (driving unit) + Type S condenser (diagonal double spiral) + Water bath |

• A rotary evaporator that fits anywhere you need it!
| The condenser can be installed on either the left or right side depending on the installation location | Easy to install and use stand base and bath |
 |
 |
| The condenser can be installed to either the left or right side of the main unit. This allows you to position the equipment considering the available bench space and your dominant hand. | The shape of the stand base and water・oil bath has been improved to a circular shape, so the bath can be faced forward regardless of the installation angle (position) of the evaporator. The bath temperature can be observed and set at any time. |
▶▶ Example of sea water concentration
• Concentration operation using vacuum controller
♦ NVC-3000 vacuum controller
◊ The controller can display not only the pressure during operation but also the cooling water temperature, bath temperature, rotary evaporator rotation speed, and vapor temperature (sensor sold separately) all in one place.
◊ The entire system automatically starts/stops when the rotary evaporator or vacuum controller starts/stops. Bath is linked only when operation is stopped.
◊ Graph below shows vacuum control function (during ramp program control)
It has the Normal Mode that allows you to change settings as desired during operation, The Auto Mode that automatically detects boiling point, controls ramp, and sets pressure simply by pressing the RUN key, and the Program Mode that controls the appropriate vacuum level by just selecting a solvent name. The appropriate vacuum conditions can always be obtained, resulting in a high solvent recovery rate.

• Shatterproof coating for glass vessels – EYELA COAT®
The coating agent is an environmentally friendly polyurethane that is resistant to breakage and features a new formulation that minimizes the scattering of glass and samples in the event of breakage. This formulation excels in chemical properties and offers remarkable transparency, making the coating virtually invisible.
• Designed for improved operability
| Liquid accumulation prevention structure | Backflow prevention structure |
 |
 |
| To minimize the accumulation of liquid that often occurs when using the condenser at an angle, a liquid accumulation prevention structure has been implemented on the receiving flask side. | The condenser attachment position is offset from the capillary, so there is no risk of condensate from the condenser flowback through the capillary tube into the sample flask. |
| Equipped with an automatic reversal function, ideal for drying and concentrating powders and solids | Since it is stepless, it can be fixed (locked) at any position when jacking up |
 |
 |
| The rotation direction of the flask (forward or reverse) can be set. Automatic rotation can also be set, making it suitable for drying powders and for drying and concentrating samples that contain solids. | The jack can be adjusted steplessly, so it can be easily fixed and released at any position to suit the sample vessel. It is easy to operate even when using a trap ball. |

• Choose from 3 types of condensers
| Type E condenser Vertical double spiral (N-1300E) |
Type V condenser Vertical double spiral (N-1300V) |
Type S condenser Diagonal double spiral (N-1300S) |
 |
 |
 |
| Type E is equipped with a compact condenser with an integrated adapter. Designed for use inside fume hoods, it features a unique design that prevents condensed liquid inside the condenser from easily flowing back into the sample flask through the capillary. | Type V is equipped with a vertical double spiral condenser. This unique design prevents condensate in the condenser from flowing back through the capillary to the sample flask. This is effective for concentrating analytical samples and other samples that must be free of contamination. | Type S is equipped with a diagonal double spiral condenser that maintains the same size while expanding the cooling surface area and improving efficiency. |
• Select a type of bath
| Bath type | Without bath | Water bath (SB1300) | Water bath with enhanced safety features (SB-1350) | Water・oil bath (OSB-2200) |
