About This Product
Students use the holder to hold a test tube in a Bunsen flame or to move a warm tube from the burner to the rack without touching the glass. Because the jaws stay closed under spring tension, the hand only needs to guide the tube while it is shaken or its contents are poured. Enquiries from Eritrea, Ecuador, Saint Vincent and the Grenadines, Luxembourg and Madagascar for the Test Tube Holder, Metal Wire receive an export quotation.
