17 mL PFA Block Digestion Tube, Rounded Interior, Threaded Top, Acid Digestion Tube, each

The 17mL Block Digestion Tube is engineered for use in block digestion units. With a rounded interior and a threaded top, it provides excellent compatibility with all acids and ensures reliable long-term storage. The PFA material offers durability and high-temperature performance.

Features:

• Service temperature range of PFA is -328°F to 500°F (-200°C to 260°C)
• Designed for block digestion units
• Compatible with all acids
• Threaded top for long-term storage
• PFA non-breakable material

Specifications:

• Volume: 17mL
• Material: PFA
• Service Temperature Range: -328°F to 500°F (-200°C to 260°C)

Why PFA:

• Resists strong acids, bases, solvents and oxidizers with no degradation
• Wide temperature tolerance suits cryogenic storage, autoclaving and high-temperature applications
• Molded by Savillex, with over 40 years of fluoropolymer molding experience

Cleaning and Sterilization:

• Initial cleaning: rinse thoroughly inside and out with deionized water (DIW); for a more thorough clean, immerse in a 1% mild alkaline detergent solution (such as Micro 90) heated to 100°C, then cool and rinse well with DIW
• Do not clean with brushes or abrasives; scratches trap metals and organic contaminants and prevent effective cleaning
• For ultratrace sample digestion work, wipe gently to remove residue, leach in hot 6M HNO₃ (about 100°C) in a Savillex vial cleaning system, and rinse thoroughly with DIW
• Sterilize by autoclave at 121°C for 90 minutes with the closure removed; PFA can be sterilized by all routine methods except gamma radiation and e-beam
