Burdick & Jackson® anhydrous solvents are specifically manufactured for moisture-sensitive applications including organic synthesis and organometallic, oligonucleotide, and combinatorial chemistry. Their water content ranges from less than 10 ppm to less than 50 ppm, with low residue eliminating the need for extra purification and drying steps in your labs. Packaged in custom-designed septum-sealed bottles to maintain low water content and ensure product integrity. Convenient packaging features a double closure, which includes an easy slip on vinyl cap with a PTFE liner and a screw-on phenolic cap with an 18mm hole. The large septum surface allows for easy access as well as enough space for repeated punctures.
