Sample loops are available for each valve product line and available in a variety of materials. Metal loops come with two stainless steel nuts and ferrules, while PEEK loops ship with two PEEK nuts and ferrules.
Sample loop shape and dimensions may vary from batch to batch due to fluctuations in tubing ID. Metal loops > 2mL are made from 1/8” OD tubing with welded 1/16” tube ends or reducing unions.
