No, they are not. If the bottles were to be autoclaved, it could cause some discoloration because of the plastic coating. In addition, autoclaving by heat will melt the plastic, and autoclaving by gas may discolor and harden the plastic. In either event, it is not recommended. To sterilize, we recommend using the non-coated bottles with […]

How long will it take for chloroform to degrade the plastic coating on the mobile phase reservoir bottles if the bottle is broken during a fall?
This is a difficult question to answer as it also depends on the severity of the impact suffered by the bottle: If the glass is just cracked it may take time (minutes to hours) for the chloroform to seep through the cracks and dissolve the polyurethane. Whereas if the impact was so severe that glass […]
