◊ This rotary evaporator features an auto-jack system that allows easy vertical movement of the evaporator (drive unit) through a simple key switch operation.
◊ In the event of a power failure, the system automatically raises the jack, ensuring that valuable samples are not left submerged in the bath.
◊ Even when a trap ball is connected, the height of the drive unit can be adjusted using the manual slide mechanism, providing consistent operability regardless of the flask volume or size of the trap ball.
◊ The up/down key switch is located on the front side of the main body, so even if the rotary evaporator is installed inside a fume hood, it can be operated with only a small opening, minimizing exposure to solvents.
◊ Teflon® vacuum seal is used. It has excellent durability and chemical resistance, and can be used for a long period of time, even when rotating at high speeds.
▶▶▶ As a simple example, let’s try concentrating seawater
• Concentration by vacuum control
♦ Connection with vacuum controller NVC-3000
◊ The controller can display not only the controlled pressure but also the cooling water temperature, bath temperature, rotary evaporator rotation speed, and vapor temperature (sensor sold separately) all at once.
◊ The entire system automatically starts or stops operation in response to the start/stop of the rotary evaporator or vacuum controller. Note: The bath operates only when stopped.
♦ Vacuum control function (during ramp program control)
It features Normal Mode where settings can be changed manually during operation, Auto Mode that detects boiling points, performs ramp control, and sets pressure automatically with just the press of the RUN key, and Program Mode that controls vacuum levels appropriately by selecting the solvent name. These modes ensure optimal vacuum conditions and a high solvent recovery rate.

• EYELACOAT® shatterproof coating for glass vessel breakage
♦ The coating material is an eco-friendly polyurethane with a new composition that makes it difficult to break and reduces the scattering of glass and samples in the event of breakage. This composition boasts excellent chemical properties and exceptional transparency, making the coating almost invisible. There is also F type condenser (N-1210BVF, BSF, BTF models) version applied to condensers, adapters, and receiving flasks.
• Designed for improved operability
| Liquid accumulation prevention structure | No backflow structure |
 |
 |
| A liquid accumulation prevention structure has been applied to the receiving flask side to reduce the pooling of liquid that often occurs when the condenser is tilted during use. | The position of the condenser is offset from the capillary, eliminating the risk of condensate from the condenser flowing back through the capillary into the sample flask. |
| Hose holder | Easy connection and disconnection of cooling hose |
 |
 |
| The hose holder is used to bundle the hoses required for connecting related products to the rotary evaporator. It helps to efficiently utilize the workspace on the laboratory bench. | The condenser and cooling hose can be easily attached and detached by using the optional one-touch connector and one-touch cooling hose set. |

| Features | The vertical condenser is uniquely designed to be space-saving with a small width and to prevent condensate from flowing back through the capillary to the sample flask. It is effective for concentrating analytical samples and other samples that should not be contaminated. The shape is newly designed to prevent liquid accumulation. It is suitable for high boiling point substances. | Horizontal condensers are low in height and economical, but can efficiently recover vapors from low to high boiling point substances. | The Dewar flask condenser is suitable for recovering low boiling point substances by using ice or dry ice-acetone in the condenser. It has a unique structure that prevents the condensate from the condenser from flowing back into the sample flask through the capillary. |
