Description

The Triode Valve (ECC82) on board is a classic dual triode vacuum tube commonly used in audio and signal amplification circuits. It is also known as 12AU7 and is prized for its balanced gain and low noise characteristics. Key Features Dual Triode Design: Contains two independent triodes within one glass envelope, each with separate cathode, grid, and plate electrodes. Heater Voltage: Can operate at either 6.3V or 12.6V heater voltages, with heater currents of 300mA (6.3V) or 150mA (12.6V). Amplification Factor: Approximately 17, offering moderate gain suited for audio preamplification and phase splitting. Plate Voltage: Maximum plate voltage around 250-300V, with plate dissipation up to 2.75W, enabling reliable operation in audio and low-frequency circuits. Transconductance: Around 2.2 mA/V, contributing to stable and linear amplification behavior. Package: Noval 9-pin glass envelope commonly used in vintage and modern audio circuits. Applications: Widely used in hi-fi preamplifiers, guitar amplifiers, microphone preamps, and other audio signal processing devices. Operational Aspects Heater-cathode voltage tolerance is around 180V, and the device offers high grid resistance for effective signal handling. The valve operates at typical currents of about 10.5mA per triode with moderate plate voltages ensuring low distortion and clean sound reproduction. Due to its dual triode design, it is often used for push-pull circuits and phase splitting in amplifiers. This ECC82 triode valve on board provides a classic, reliable component well-suited for audio amplification and signal processing tasks in various electronic and musical equipment.

Laboratory Chemicals

Ferrous borate extra pure is a high-quality iron(II) borate compound (commonly referred to as iron(II) borate or ferrous borate), used predominantly in laboratory and industrial settings for applications that demand high purity standards. It typically appears as a fine, air-sensitive solid and is valued for its chemical stability under controlled conditions. The compound features a high degree of purity, making it especially suitable for analytical work, advanced research, and select industrial processes.​ Product Description for Website Ferrous borate extra pure (Iron(II) borate) is a premium-grade inorganic salt prepared to strict purity standards, ensuring low levels of contaminants and accurate stoichiometry for scientific and technical applications. The product is carefully processed and packaged to maintain its chemical integrity and support reliable results in laboratory analysis and synthesis.​ Synonyms: Iron(II) borate, Ferrous borate Chemical Formula: Fe(BO2)2 (hydrated forms and other stoichiometries possible) Appearance: Pale solid, may be air-sensitive Grade: Extra pure (analytical/research grade) Applications: Used in specialized laboratory analyses, catalyst systems, advanced inorganic synthesis, and as a starting material in certain industrial applications where high purity is critical.​ Key Features High purity and controlled chemical analysis for reliable, reproducible results Packaged with minimal contamination risk and maximum shelf-life Suitable for use in chemical research, formulation, and manufacturing at the analytical level​ Safety & Handling Ferrous borate is generally stable under typical laboratory conditions but should be handled with care as it may be sensitive to atmospheric moisture and air. Use standard personal protective equipment and store in a tightly sealed container in a cool, dry environment.​ This concise description is suitable for use as a base product summary or catalog entry for e-commerce or laboratory supply websites, ensuring clarity for research and procurement professionals.​
