0% T Black Block for Spectrophotometers by Azzota 13x13x48mm

Description

Product Overview

The 0% T Black Block from Azzota is engineered as a high‑precision calibration standard for spectrophotometers and colorimeters used in research, quality control, and industrial color matching. Measuring 13x13x48mm, the block is fabricated from optically pure black material that provides a true zero‑transmission reference across the visible spectrum. Its compact size allows it to fit easily into standard sample holders, while the robust construction ensures long‑term stability even under frequent handling. The block is supplied in a protective case that guards against dust, scratches, and moisture, preserving its optical properties for years of reliable use.

Usage

Designed for laboratory environments, the 0% T Black Block serves as a baseline reference during routine instrument verification, performance checks, and method validation. Place the block in the spectrophotometer sample compartment and run a standard zero‑transmission scan to confirm that the instrument reads true darkness. This procedure helps detect any stray light, detector drift, or alignment issues before critical measurements are taken. The block is also suitable for field‑portable spectrophotometers used in paint, ink, and textile industries, where quick verification of instrument accuracy is essential to maintain product consistency.

Because the block is non‑reflective and absorbs virtually all incident light, it is ideal for calibrating devices that require a true black reference, such as gloss meters, haze meters, and colorimeters that assess translucency. Users can integrate the block into standard operating procedures, ensuring that every batch of samples is measured against a consistent baseline, thereby reducing variability and enhancing confidence in analytical results.

FAQ

What does a 0% T black block measure?

The block provides a zero‑transmission (0% T) reference, meaning it absorbs virtually all light that passes through it. This allows spectrophotometers to be calibrated against a true black baseline, ensuring that subsequent measurements are accurate and free from stray light interference.

How often should I use the black block for calibration?

It is recommended to perform a zero‑transmission check at the start of each workday, after any instrument relocation, and whenever you notice unexpected variations in measurement results. Regular checks help maintain instrument accuracy and detect potential drift early.

Is the block compatible with all spectrophotometer models?

The block’s dimensions (13x13x48mm) are designed to fit the sample compartments of most standard laboratory spectrophotometers and colorimeters. However, always verify the sample holder size in your instrument’s manual to ensure a proper fit.

Can the block be used for both visible and UV measurements?

Yes, the black material absorbs light across a broad spectral range, making it suitable for both visible and ultraviolet calibration tasks. For UV applications, ensure that the instrument’s detector is capable of measuring the low‑signal levels associated with a zero‑transmission reference.

What is the recommended storage condition for the black block?

Store the block in its protective case in a clean, dry environment away from direct sunlight and extreme temperature fluctuations. Proper storage helps preserve its optical properties and extends its usable lifespan.
