Vials, Screw Top, Glass. Clear / Clear Insert, 300ul with Write-On Patch and fill lines, Fused Insert™, 9-425mm threads, 12x32mm outer dimensions. For use as an autosampler vial. AQ Brand. 100/PK.
Additional Info:
The 9532S‑WCV AQ™ Fused Insert Autosampler Vial is a high‑precision, low‑volume vial designed for laboratories that require excellent recovery, reliable sealing, and consistent autosampler performance. Both the vial and the permanently fused insert are manufactured from first hydrolytic, Class A, Type‑33 clear borosilicate glass, ensuring dependable chemical compatibility and dimensional consistency.
The 300 µL fused insert is engineered for low‑volume injections and delivers a typical residual volume as low as ~3 µL for many autosampler and needle configurations. Unlike removable inserts, the fused design eliminates variability, movement, and leakage concerns associated with multi‑piece systems.
Key Features
Type‑33 Borosilicate Glass Construction
First hydrolytic, Class A glass
Excellent chemical durability and optical clarity
Suitable for routine and regulated analytical workflows
Precision Fused Insert™ Design
Permanently fused insert for maximum stability

Maximizes sample recovery
Reduces risk of autosampler needle damage
Insert is not bottom‑attached, preventing cracking and leaks observed in competitive designs
Ceramic Write‑On Patch and Fill Lines
Permanently fired ceramic labeling surface
Resists smearing and scratching when exposed to solvents
Fill lines support consistent sample preparation
Why Choose a Fused Insert™ Autosampler Vial?
Fused insert vials are selected when laboratories need low‑volume accuracy without the risks of removable inserts, including misalignment, leakage, or breakage. The AQ™ fused insert design provides:
Consistent vial‑to‑vial geometry
Reliable sealing with standard screw caps
Excellent recovery for limited or valuable samples
This vial is well suited for routine analytical, LC‑MS, and regulated workflows where reproducibility and robustness are critical.
Typical Applications
LC‑MS and UHPLC autosampling
Low‑volume sample injections
Routine analytical and regulated methods
Laboratories seeking fused‑insert reliability without wide‑tip geometry
