IBI Scientific SS-3014 Two-Piece Cap for 300 mL Flask

The TUNAIR™ two piece cap assemblies are constructed of polypropylene and are resistant to most solvents. All flasks and caps are fully autoclavable prior to reuse and filter linings can also be autoclaved or simply replaced. Two piece caps are available in 300 ml.

Replacement Instructions:

To replace the filter lining in the cap assembly, simply pinch the flanges of the inner-closure shell until they snap loose. Then, pull apart and remove used lining. Replace the lining by sandwiching it between two parts of the cap and snap the cap back together. When reassembling the cap, ensure the flanges from the inner piece snap into the mated grooves in the outer piece. This will ensure the cap assembly stays together during use.

Cleaning Instructions:

All TUNAIR Erlenmeyer flasks and caps can be cleaned by soaking in water with a light detergent (i.e. Joy) solution to loosen dirt and contaminants, then air dry. All TUNAIR flasks and caps can be autoclaved, if required.

Two Piece Cap:

The flasks have a special cap and filter system that promotes gas exchange and maintains sterility of the growth culture during use. The inner portion of the cap unsnaps from the outer portion by pushing in the tabs on the side of the cap assembly and then pulling the insert out.

Cap & Filter assembly: 

Once you have the 2-piece cap assembly apart place the corresponding filter size inside the cap and the re-assemble the inner and outer cap pieces making certain to align the tabs with their associated holes. Once clipped into place, make certain the filter completely covers the cap assembly openings.
