250ml Glass Round Media Storage Bottles with GL45 Screw Cap, 3.3 Borosilicate Glass, Karter Scientific 232H3 (Pack of 2)
These heavy duty 3.3 borosilicate glass round bottles can be used for storage as well as mixing and sampling. They include a linerless, one-piece autoclavable blue polypropylene plug seal GL45 threaded cap with a drip-free pouring ring. Max temperature of 140 degrees Celsius (284 degrees Fahrenheit). NON-ALKALINE-EARTH BOROSILICATE GLASS (BOROSILICATE GLASS 3.3): The B2O3 content for borosilicate glass is typically 12-13% and the SiO2 content over 80%. High chemical durability and low thermal expansion (3.3 × 10-6 K-1) - the lowest of all commercial glasses for large-scale technical applications - make this a multitalented glass material. High-grade borosilicate flat glasses are used in a wide variety of industries, mainly for technical applications that require either good thermal resistance, excellent chemical durability, or high light transmission in combination with a pristine surface quality. Other typical applications for different forms of borosilicate glass include glass tubing, glass piping, glass containers, etc. especially for the chemical industry. ALKALINE-EARTH-CONTAINING BOROSILICATE GLASSES (BOROSILICATE GLASS):In addition to about 75% SiO2 and 8-12% B2O3, these glasses contain up to 5% alkaline earths and alumina (Al2O3). This is a subtype of slightly softer glasses, which have thermal expansions in the range (4.0-5.0) × 10-6 K-1.
