Stonylab Chromatography Column 1in Borosilicate

Description

Product Overview

The Stonylab SL001346 chromatography column is engineered for high‑precision gas chromatography. It features a 1 inch inner diameter and a 12 inch effective length, constructed from G3.3 borosilicate glass for superior thermal resistance and chemical inertness. The column includes a 24/40 standard taper upper joint, a PTFE valve for fine flow regulation, and a G2 sand plug with a 0.0016‑0.0031 inch aperture at the base, ensuring reliable performance in demanding analytical tasks.

Usage

Designed for laboratory environments, this column excels in separating mixed organic compounds in gas chromatography (GC) systems. It is suitable for research labs, quality control facilities, and industrial analytical stations where accurate, reproducible results are essential. The durable glass construction tolerates high temperatures, making it compatible with a wide range of solvents and sample types.

FAQ

What solvents can be used with this column?

The borosilicate glass construction tolerates a wide range of organic solvents, including hexane, methanol, and chloroform, up to the temperature limits specified by the manufacturer.

How does the PTFE valve improve performance?

The PTFE valve provides low dead volume and chemical resistance, allowing precise adjustment of carrier gas flow and reducing peak broadening.

Is the column compatible with standard GC instruments?

Yes, the column features a 24/40 standard taper upper joint, making it compatible with most commercial GC systems that accept standard fittings.

What is the purpose of the G2 sand plug?

The sand plug contains a fine sand core with a controlled aperture, which helps to evenly distribute the sample and improve separation efficiency for complex mixtures.

What warranty does Stonylab provide?

Stonylab offers a one‑year limited warranty covering manufacturing defects. If the column arrives damaged, contact support for a replacement or refund.
