CTV-0930-RS - VIALS 300ul Fused Insert Screw 9mm Clear 100

The CTV-0930-RS RSA™ Low Volume Screw‑Top Vial is designed for accurate, low‑volume autosampler injections where analyte recovery, chemical inertness, and reproducibility are critical. Manufactured from first hydrolytic, Class A, Type‑33 reduced‑surface‑activity borosilicate glass, these vials minimize adsorption and eliminate sodium contamination that can compromise sensitive analyses.

The 300 µL fused insert design improves sample recovery at low fill volumes while maintaining precise autosampler compatibility. Integrated ceramic write‑on patches and fill lines allow permanent labeling without smearing, even in aggressive solvent environments.

Key Features

First Hydrolytic, Class A RSA™ Borosilicate Glass

• Type‑33 borosilicate glass with certified reduced surface activity

• Consistent glass chemistry from lot to lot

• Manufactured in an ISO 9001:2015 certified facility

Ceramic Write‑On Patch and Fill Lines

• Permanently fired ceramic labeling area

• Resistant to solvent attack, scratching, and smearing

• Enables clear identification without compromising vial integrity

Fused Insert™ Low‑Volume Design

• Insert is fused above the rim of the vial for improved sealing

• Optimized bottom depths for maximum sample recovery

• Protects autosampler needles while ensuring injection precision

Reduced Adsorption and Sodium‑Free Performance

• Minimizes adsorption of basic and polar compounds

• Does not leach sodium (Na) into sample solutions
