Features

• A low-alkali method.
• It was born as a freeze-drying manufacturing agent and is also useful for the highest-grade, highly-airtight storage.
• Equipped with the characteristics of a vial bottle and the ease of a screw port bottle, it has a cap for heat and freeze resistance.
• Because the entire cap is a screw cap, safety is also excellent.
• You don't have to worry about getting injured by the aluminum cut during handling like the conventional aluminum seal type.
• Uses a butyl rubber stopper for freeze-drying to seal tightly and allow repeated use.
• It is ideal for storing organic solvents such as standard solutions (Does not volatilize or change in concentration) without any change in liquid volume.
• Fully automatic forming reinforced hard glass enables negative storage, which is considered difficult.
