功能

• The block cap is hard to fall down even when vibration is applied during opening/closing of refrigeration/freezer or transportation. The multi-stacking shape of the top surface allows various stacking.
• By making the cap square against the cylindrical body container, the cold air circulates in the cold insulation environment and the contents can be stored stably.
• All parts of the container are made of polyethylene.
• It is hard to break even when subjected to impact in the freezing environment.
• With an inner plug, which is rare for small capacity, it keeps the contents fresh.
• The use of 3-thread screws increases the opening and closing speed and reduces the working time when using large volume samples.
• It can be directly put into the agitator with the contents.
