High-Performance & Easy-to-Use Genuine Rotary Evaporator Accessories

Rotary joints (Vapor ducts)

Featuring the EYELA brand, genuine rotary joints are manufactured under strict quality control, ensuring uniform wall thickness and zero runout. A variety of types are available to suit your specific applications: standard type, heavy-duty thick-walled type for large-capacity flasks, and grease-free taper joint type. Quartz glass types for analytical applications can also be custom-manufactured upon request.

Sample (pear shaped) flasks

These are genuine sample flasks. Featuring minimal runout and virtually no air bubbles, the sample flasks are built to withstand rigorous use under high rotation and high vacuum.

Receiving flasks

These are genuine receiving flasks. Featuring minimal runout and virtually no air bubbles, the sample flasks are built to withstand rigorous use under high rotation and high vacuum.

Trap balls

Bearing the EYELA brand, these genuine trap balls deliver stable quality with zero runout. In the event of bumping, they prevent the sample from flowing back into the flask or contaminating the receiving flask. When using a small-capacity sample flask, they serve a dual purpose as both a bumping prevention device and a coupling adapter. For more details about a trap ball, click here.
