TOUGH BOROSILICATE GLASS: Boro 3.3 glass has very low coefficients of thermal expansion, making it resistant to thermal shock. It also has a high chemical resistance in corrosive environments
GRADUATED: Bottles have permanent white enamel graduations at 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000 and 4500ml
GL45 SCREW CAP: Orange GL45 screw cap provides a tight seal
AUTOCLAVABLE: Maximum temperature 140°C. Note: Do not tighten the cap immediately after autoclaving - the resulting cooling vacuum could break the glass
