Product description

High-purity silica gel with fluorescent indicator F254 and particle size <20 μm for TLC separations.

Silica Gel GF254 is a high-purity grade silica gel specifically designed for thin-layer chromatography (TLC) applications. This versatile adsorbent is widely used for the separation and analysis of complex mixtures in various scientific disciplines.

Key features:

Fluorescent Indicator: Incorporates a fluorescent indicator (F254), enabling easy visualization of separated compounds under UV light.
High Purity: Composed of silica gel with approximately 15% calcium sulfate as a binder, ensuring consistent and reliable chromatographic performance.
Optimal Particle Size: Features a particle size of less than 20 μm, providing high-resolution separations.
Versatile Applications: Suitable for a wide range of compounds, from polar to non-polar, making it ideal for diverse analytical needs.

Applications:

Pharmaceutical Analysis: Employed in the separation and quantification of pharmaceutical compounds, ensuring quality control and regulatory compliance.
Biotechnology Research: Utilized in the analysis of biomolecules, aiding in the development of biopharmaceuticals and molecular diagnostics.
Environmental Studies: Applied in the detection and quantification of environmental pollutants, contributing to environmental monitoring and safety.
Food Safety: Used to identify and quantify additives, contaminants, and natural compounds in food products, ensuring consumer safety.

Commonly used in:

University Laboratories: Supports academic research and education in analytical chemistry and related fields.
Pharmaceutical Companies: Integral to quality control and research and development processes.
Biotechnology Firms: Essential for the analysis and development of biotechnological products.
Environmental Agencies: Aids in monitoring and analyzing environmental samples for pollutants.

Silica Gel GF254 has been a staple in chromatographic analysis for several decades and continues to be relevant in modern analytical laboratories due to its reliability and versatility.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
