This \"double-threaded\" design serves as a bridge between the rotary evaporator’s vapor tube and small-scale sample containers. One end of the adapter features a standard SJ 24\/40 ground glass joint, which fits securely into the drive head of most common rotary evaporators, while the other end consists of a high-performance PBT (polybutylene terephthalate) threaded connector.\u003c\/p\u003e\n\u003cp\u003eThe primary technical advantage of this connector is its compatibility with 20-400 GPI threaded vials, which are the industry standard for 20 mL to 40 mL scintillation and sample vials. By utilizing an internal PTFE-faced silicone septa or gasket within the threaded cap, the adapter maintains a vacuum-tight seal, allowing for efficient solvent removal under reduced pressure directly into the vial. This streamlined workflow is critical for high-throughput labs as it minimizes sample loss, prevents cross-contamination from intermediate vessels, and allows the sample to remain in its final storage container once the evaporation process is complete. The glass body is constructed from heavy-wall borosilicate glass to withstand the mechanical stresses of rotation and the thermal gradients of the heating bath.\u003c\/p\u003e","brand":"Chemglass","offers":[{"title":"Default Title","offer_id":48658270388476,"sku":"10211","price":52.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/chemglass-rotary-evaporator-connector-double-threaded-for-20-400-vials-glassware-adapters-chemglass-966057.jpg?v=1767917055","url":"https:\/\/lifesciencestrading.com\/products\/chemglass-rotary-evaporator-connector-double-threaded-for-20-400-vials","provider":"Life Sciences Trading","version":"1.0","type":"link"}
