Product Overview
Tetraethyl orthosilicate (TEOS) GPR RECTAPUR® is a high-purity silica precursor designed for demanding laboratory applications requiring consistent performance. This clear, colorless liquid features a minimum 98% purity level, ensuring reliable results in sol-gel synthesis, thin film deposition, and surface functionalization processes. The GPR grade designation indicates its suitability for general research applications where reagent-grade purity is essential. With a boiling point of 168°C and density of 0.933 g/mL at 20°C, this TEOS formulation offers excellent stability and controlled hydrolysis rates. The RECTAPUR® quality standard guarantees low metal ion content (<10 ppm) and minimal water content (<0.1%), preventing unwanted side reactions. Packaged in a 1-liter HDPE bottle with a tamper-evident seal, this product maintains its integrity during storage and transport. The chemical's tetraethyl structure provides optimal reactivity for silica network formation while minimizing ethanol byproduct formation during processing. Ideal for applications requiring precise stoichiometric control, this TEOS formulation delivers consistent performance batch after batch.
FAQs
1. What is the typical shelf life of this TEOS product?
When stored unopened in its original container at room temperature, this TEOS maintains its specifications for 24 months from the date of manufacture. Always check the label for the exact expiration date.
2. Can this TEOS be used for medical device coatings?
While this is a high-purity GPR grade product, medical applications typically require specialized grades with additional certifications. We recommend consulting with your quality assurance team regarding specific regulatory requirements.
3. What safety precautions should be taken when handling this chemical?
TEOS is classified as flammable and harmful if inhaled or absorbed through skin. Always use in a well-ventilated fume hood, wear appropriate PPE including nitrile gloves and safety goggles, and avoid all ignition sources.
4. How does this compare to TEOS from other brands?
Our RECTAPUR® TEOS undergoes rigorous quality control testing for metal impurities, water content, and hydrolysis stability. The consistent batch-to-batch performance makes it particularly suitable for applications requiring precise silica structure formation.
5. What’s the recommended storage temperature range?
For optimal stability, store between 15-25°C in a tightly sealed container. Avoid prolonged exposure to temperatures above 30°C as this may accelerate hydrolysis and affect product performance.
