FLASKS BUCKNER FILTRACTION (Bolt Neck)

What is it?

The Buchner Filtration Flask, also known as a Vacuum Flask, is a vital component for suction filtration. This "Bolt Neck" version features a reinforced, thick-rimmed plain neck. Unlike socket-style flasks, the bolt neck is specifically designed to accommodate rubber stoppers, bungs, or Gootch rubber gaskets, providing a flexible and secure seal for various funnel sizes.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Manufactured from superior heat-resistant glass that can handle high vacuum levels and thermal shock safely.
• Reinforced "Bolt" Neck: The neck is crafted with a heavy-duty rim to withstand the pressure of tightly fitted rubber stoppers without chipping or cracking.
• Integral Side Tubulation: Features a sturdy side arm (tubulation) designed for a secure, leak-free connection with standard vacuum rubber hoses.
• Extra-Thick Glass Walls: Meticulously built with thick, uniform walls to prevent the risk of implosion under high-pressure vacuum filtration.
• Wide Conical Base: Provides excellent stability on the benchtop, even when connected to heavy-duty vacuum lines or holding large volumes of filtrate.

Available Capacities

Our Bolt Neck Filtration Flasks are available in a variety of standard laboratory sizes: 100mL, 250mL, 500mL, 1000mL, and 2000mL.

Safety Commitment: Every Buchner Flask is carefully annealed to remove internal glass stress and inspected for uniform wall thickness, ensuring it meets strict safety standards for vacuum work in your laboratory.
