Selecting Laboratory Cartridge and Filter Systems

Laboratories depend on pure, clean water for the highest quality work outcomes. Different applications and processes require different levels of water purity, designated by the ASTM. For example, washing glassware in the lab can usually be done with type II or III water for the final rinse. Whereas type I water is most often recommended when preparing reagents, solutions, or samples for processing. Water purification methods vary depending on the contaminants that need to be removed to meet ASTM standards. The following flow chart can help you choose which type of Thermo Fisher deionizer and filtration to use.

How to select your Filter System

We offer a complete line of cartridge and filter systems for all your single-step purification and pretreatment needs. Use the Bantam Deionizer, Hose Nipple Cartridges, or B-Pure cartridges for simple, single-step purifications. The high-capacity B-Pure cartridges also serve as an excellent pretreatment system for our Type 1 or Type 2 systems, such as the Nanopure or TII.
