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 […]
The mobile phase bottle caps are made of polypropylene with a PTFE insert. The O-rings are made of Viton® and coated with PTFE. The caps, inserts, and O-rings are made for use with GL 45 screw thread bottles. The ring has an outer diameter of approximately 36.4 mm and an inner diameter of approximately 28.6 mm.

From Wikipedia Piston-driven Air Displacement Pipettes These are the most accurate and precise pipettes. They are more commonly used in biology, though they are commonly used by chemists as well. The plastic pipette tips are designed for aqueous solutions, and are not recommended for use with organic solvents which may dissolve the plastic. Link to […]
