The Natural bottles are interchangeable with the majority of the Philips Avent range: electrical and manual breast pumps, sealing discs, storage cups, bottle warmers, electric and microwave sterilisers.
• The Natural nipples, screw ring and caps of both Natural and Natural glass bottles are interchangeable.
• The Natural bottles do fit the Classic electric steriliser. The steriliser will fit 5 Natural bottles instead of 6 Classic bottles.
• The Natural bottles do fit the Classic microwave steriliser. If you have an older version of the microwave steriliser, you can order a new inner tray at consumer care (http://philips.com/support)
