The Septum Cap Capper is perfect for use with all 96-format Azenta sample storage tubes with TPE Septum Caps. Simple use of spacers enables the depth of capping action to be adjusted allowing the device to also seal most other leading brands of SBS-compliant tube racks with their corresponding TPE cap mats.

Using the Semi-Automated Septum Cap Capper in conjunction with Azenta racks featuring proprietary TubeLock functionality enables automatic locking and unlocking of tubes within the rack.
