Scicalife Cobalt Blue Glass Sheet Filtering Lens 1.96×1.96 Inches

Description

Product Overview

The Scicalife Cobalt Blue Glass Sheet is engineered specifically for scientific observation of flame color reactions. Crafted from a proprietary cobalt metaaluminate matrix (Co(AlO2)2), the glass acquires a deep blue hue that naturally filters out sodium emissions, allowing researchers to see subtle variations in flame spectra with exceptional clarity. Measuring precisely 1.96 x 1.96 x 0.19 inches and weighing only 1.44 ounces, the sheet offers a compact footprint that fits easily into standard laboratory holders, burners, and furnace windows. Its high‑temperature resistance enables continuous exposure to temperatures well above 1000 °C without deformation or discoloration, making it suitable for both low‑heat bench work and high‑heat industrial furnace applications. The sheet’s flat, optically smooth surface minimizes light scattering, delivering consistent, repeatable results across multiple experiments. Scicalife, a recognized supplier of laboratory glassware, guarantees that each sheet meets strict quality standards, providing a reliable component for any flame spectroscopy or colorimetric analysis workflow.

Usage

In a chemistry laboratory, the cobalt blue sheet is placed directly in the path of a Bunsen or propane flame to observe the characteristic colors produced by various metal salts. By eliminating the dominant yellow sodium line, the sheet reveals the true hues of copper, potassium, lithium, and other elements, facilitating accurate qualitative analysis. Beyond academic settings, the sheet is widely adopted in steel mills, cement factories, and glass production plants where furnace operators monitor flame stability and composition to optimize fuel efficiency and product quality. Its durability allows it to be mounted on rotating burners, inserted into quartz tubes, or used as a protective window in spectroscopic instruments. The sheet’s lightweight nature simplifies cleaning and replacement, reducing downtime during routine maintenance. Whether employed in a teaching lab, a research facility, or an industrial furnace, the product delivers consistent optical performance, helping technicians and scientists achieve reliable data without the need for complex calibration procedures.

FAQ

What temperature range can the cobalt blue glass sheet withstand?

The sheet is designed to tolerate continuous exposure to temperatures up to approximately 1200 °C, making it suitable for both laboratory burners and industrial furnace applications.

How does the cobalt blue color improve flame observation?

The cobalt blue pigment absorbs the bright yellow emission from sodium, which is common in many flame tests. By suppressing this dominant wavelength, the sheet allows the subtle colors of other metal ions to become visible, improving the accuracy of qualitative analysis.

Can the sheet be reused after cleaning?

Yes. The glass can be gently cleaned with distilled water and a soft lint‑free cloth. Avoid abrasive cleaners or rapid temperature changes to prevent thermal shock, and the sheet will retain its optical properties for many cycles.

Is the product compatible with spectroscopic equipment?

Absolutely. Its flat, optically clear surface makes it an ideal window for spectrometers, flame photometers, and other analytical instruments that require a stable, heat‑resistant viewing port.

What is the recommended method for installing the sheet in a furnace?

Secure the sheet in a metal or ceramic holder that matches its dimensions, ensuring a snug fit to prevent movement. Position the sheet so the coated side faces the flame, and allow the furnace to reach operating temperature gradually to avoid thermal shock.
