Starnacells 1-G-40 Optical Glass Spectrophotometer Cell 40mm Path 14ml

Description

Product Overview

The Starnacells 1‑G‑40 optical glass cell is engineered to meet the demanding requirements of modern UV‑Vis spectrophotometry. Constructed from high‑purity optical glass, the cell provides exceptional transmission across the ultraviolet and visible spectrum, minimizing stray light and ensuring accurate absorbance readings. With a precisely machined rectangular geometry, the cell offers a 40 mm optical path length, the standard for many quantitative analyses, and a nominal volume of 14 ml, allowing sufficient sample quantity while maintaining a compact footprint. The glass material is chemically inert, resisting attack from acids, bases, and organic solvents commonly used in laboratory protocols. This durability translates into a long service life, reducing the need for frequent replacements and supporting sustainable laboratory practices.

Dimensions are carefully controlled to fit seamlessly into standard cuvette holders found on most bench‑top spectrophotometers. The external dimensions of the cell are 40 mm × 10 mm × 10 mm, providing a stable platform that resists wobble during measurement. The cell features a smooth, polished interior surface that eliminates scattering and ensures repeatable optical performance. The clear, transparent walls allow easy visual inspection of the sample, facilitating quick checks for bubbles, precipitates, or phase separation before measurement. The robust construction also tolerates repeated cleaning cycles, whether by manual washing or automated cleaning systems, without compromising optical clarity.

Usage

Designed for a broad range of applications, the Starnacells 1‑G‑40 cell is suitable for chemistry, biochemistry, environmental testing, and pharmaceutical analysis. Researchers conducting kinetic studies, concentration determinations, or purity assessments can rely on the cell’s consistent path length to generate reproducible data across multiple runs. The 14 ml volume accommodates a variety of sample types, from dilute aqueous solutions to more viscous organic mixtures, without the risk of overflow or spillage. Because the cell is made from high‑quality optical glass, it is ideal for measurements that require high sensitivity, such as detecting low‑concentration analytes or monitoring subtle spectral shifts.

In educational settings, the cell provides a reliable teaching tool for students learning the fundamentals of spectrophotometry. Its durability withstands the rigors of classroom use, while the clear glass allows instructors to demonstrate proper sample handling techniques. In industrial laboratories, the cell’s compatibility with automated sample changers enables high‑throughput workflows, increasing productivity without sacrificing data quality. Whether used in a research bench, a quality‑control lab, or a field‑portable spectrophotometer, the Starnacells cell delivers dependable performance under a variety of environmental conditions.

FAQ

What type of glass is used in the 1‑G‑40 cell?

The cell is made from high‑purity borosilicate optical glass, which offers excellent transmission from 200 nm to 800 nm and resists chemical attack from most laboratory reagents.

Can the cell be used with automated sample changers?

Yes, the rectangular dimensions and standard cuvette holder compatibility make the 1‑G‑40 cell fully compatible with most automated spectrophotometer sample‑handling systems.

How should the cell be cleaned after use?

We recommend rinsing the cell with distilled water followed by a brief soak in a mild detergent solution. For stubborn residues, a short exposure to a 10 % nitric acid solution can be used, followed by thorough rinsing and drying with lint‑free tissue.

Is there a warranty on the product?

Starnacells provides a one‑year limited warranty covering defects in material and workmanship. Our customer service team will arrange replacement or repair if any issue arises within the warranty period.

Do you offer custom path lengths or volumes?

Yes, we can manufacture custom cells with alternative path lengths or volumes to meet specific experimental requirements. Please contact our sales department for a quote and lead‑time details.
