This lab-grade glass cartridge vial is specially developed for the storage and preservation of peptide lyophilized powder. It is manufactured from high?quality transparent borosilicate glass material, featuring excellent chemical resistance, low?extractable property and stable structural performance, which can effectively avoid adverse interaction between container and sensitive peptide samples during laboratory storage. Each cartridge vial is individually vacuum?sealed in aluminum foil bag to keep clean condition and reduce external contamination risk during transportation and handling. This series of glass cartridges matches mainstream laboratory peptide?dispensing pen devices and is suitable for multiple kinds of research?grade peptide lyophilized powder. Multiple dimension specifications are available to satisfy different experimental volume requirements. We support flexible OEM service including customized size selection, neutral?packing without our logo, and private?label options. Both small trial sample orders and large?volume bulk procurement are acceptable. Strict pre?shipment inspection is carried out before delivery to check glass surface integrity and sealing condition.
