Caps, Screw Top, Solid, with a Red-Orange Silicone Rubber / TEF liner, in "knurled", closed Blue Caps. For use with 9-425mm thread,12x32mm autosampler vials. MICROSOLV Brand 1000/CS.
Additional Info:
The 9502S‑09‑SR‑K screw caps are a standard, stocked solid‑top storage solution used to convert autosampler vials into dedicated storage vials. These caps do not contain a pierceable septa and are not intended for autosampler injection.
Each cap is fitted with a red‑orange silicone rubber liner backed with a TEF facing. The TEF liner provides chemical inertness while offering a lower‑cost alternative to PTFE‑only liners. With a liner hardness of approximately 53° Shore D, this design delivers a balance of rigidity and compression suitable for general solvent and sample storage.
The silicone rubber backing applies elastic force against the vial rim, improving the seal compared to rigid liners alone. This makes these caps well suited for volatile compounds, solvent‑rich samples, and short‑ to medium‑term storage, where minimizing evaporation or solvent loss is important.
The solid, closed‑top design eliminates needle penetration points entirely, reducing the risk of leaks, evaporation, or contamination during storage and handling.
The knurled polypropylene exterior allows secure manual handling and reliable torque application, and the caps are compatible with standard 9‑425 autosampler vial formats.
This 1000‑count case format is ideal for laboratories that routinely repurpose autosampler vials for sample storage, transport, or staging.
