PTFE Polytetrafluoroethylene Flower Basket Small Silicon Wafer Cleaning Rack Carrier for Laboratory Acid Pickling

Product Overview

This high-performance laboratory carrier, often referred to as a flower basket, is an essential tool for the wet chemical processing of delicate substrates. Engineered from high-purity polytetrafluoroethylene (PTFE), the equipment is designed to hold wafers, silicon slices, and optical components securely during immersion in aggressive cleaning or etching solutions. By utilizing the inherent chemical inertness of premium fluoropolymers, this unit provides a contamination-free environment for sensitive materials, ensuring that critical research and production processes maintain the highest standards of purity.

The primary use cases for this system span across semiconductor manufacturing, solar cell fabrication, and advanced materials research. It is particularly effective in environments where glass or metal carriers would fail due to corrosion or ion leaching. The specialized geometry of the carrier allows for maximum surface exposure to chemical reagents, facilitating uniform cleaning and etching across all loaded samples. This makes the unit an indispensable asset for facilities involved in micro-electromechanical systems (MEMS) and precision optics.

Built for reliability under demanding conditions, the system offers exceptional thermal stability and mechanical robustness. Laboratory personnel can rely on its performance when subjected to repeated cycles of strong acid baths and high-temperature drying processes. The combination of precision CNC machining and superior material selection ensures that the equipment remains a long-term, dependable solution for critical sample preparation and cleaning workflows in both industrial and academic settings.

Key Features

• High-Purity PTFE Construction: Manufactured from 100% virgin PTFE, the equipment offers absolute chemical resistance to strong acids (including HF, aqua regia), bases, and organic solvents, preventing sample contamination and carrier degradation.
• Optimized Fluid Dynamics: The scientifically engineered slot distribution and open-frame design ensure that cleaning solutions flow freely and evenly around every substrate, eliminating dead zones and ensuring consistent processing results.
• Integrated Safety Handle: Featuring a robust, ergonomically designed handle, the unit allows for the safe manual transfer of samples into and out of deep chemical tanks, minimizing the risk of operator exposure to hazardous reagents.
• Exceptional Thermal Range: The material's inherent properties allow the rack to operate reliably in temperatures ranging from cryogenic levels up to 260°C, making it suitable for both chilled etching and high-heat cleaning processes.
• Anti-Adhesive Surface Properties: The naturally smooth and low-friction surface of the fluoropolymer prevents the adhesion of particles and chemical residues, simplifying the cleaning of the carrier itself and reducing cross-contamination risks.
• Precision CNC Fabrication: Each unit is crafted through advanced CNC machining processes, ensuring high dimensional accuracy for slot widths and spacing, which is critical for protecting fragile silicon wafers from mechanical stress.
• Structural Stability: Despite its lightweight design, the carrier maintains high structural integrity under immersion, preventing warping or sample slippage even during agitation or ultrasonic cleaning cycles.
