PFA-Coated Heating Rack 300*200mm, for 7ml vials

Product Overview

The PFA-Coated Heating Rack is a critical performance-enhancing accessory for ultra-clean laboratories. While flat hot plates are versatile, they often suffer from inefficient heat transfer when used with round-bottom or thick-walled PFA vials. This specialized rack acts as a high-efficiency thermal bridge. By nesting the vials within precision-machined wells, it creates a "mini-dry block" environment on top of your existing hot plate. This ensures uniform digestion, prevents "cold spots" at the top of the sample, and protects the hot plate surface from accidental mechanical wear.

Product Synergy & Workflow

Optimized for the high-purity heating chain:

• Inert Hot Plates (Graphite/Aluminum): Designed to sit directly on the hot plate surface, converting a flat heater into a high-throughput digestion block.

• PFA Vials (15ml, 22ml, 30ml): The primary partners; the rack is designed to hold these vials securely during evaporation or acid digestion.

• PFA Reflux Covers: Can be used on the vials while in the rack to facilitate a fully closed, contamination-free digestion cycle.

Application Fields & Industries

• Trace Element Analysis: Ensuring identical heating conditions for all samples and blanks in ICP-MS preparation.

• Geochemistry: Accelerated dissolution of geological samples using concentrated HF/HNO₃ mixtures.

• Semiconductor Quality Control: Controlled evaporation of high-purity chemicals where temperature precision is critical.

• Environmental Testing: Large-batch processing of soil and water extracts for heavy metal screening.
