Product Details

Developed to exceed the demands of sample security, management and tracking in modern high-density storage applications. Designed for reduced sample loss: significant amounts of liquid can become trapped within a standard design screw cap, resulting in potential loss of valuable sample.

Studies demonstrate that Azenta Life Sciences cap design, with a reduced hollow, reduces this effect by lowering liquid retention whilst maintaining seal quality. This hollow area on the cap can catch sample, and surface tension then makes cap removal difficult.

Compatible with all Azenta Life Sciences sample storage tubes with a screw top, caps are available for use with either external or internal thread Azenta Life Sciences screw top tubes. Manufactured from high-quality virgin polypropylene.

Key Features

Pratical Design

High chemical resistance
Autoclavable
Available in up to 10 different colors to aid sample identification
Suitable for sealing external and internal thread tubes
Broad operating temperature range*: -196°C to +121°C

*Not for use in liquid phase nitrogen

Options

External thread screw caps, standard

A deforming compression seal more effective than a silicone alternative
A non-silicone seal means the cap can never be over-tightened
Caps and tubes are manufactured from the same material, preventing differential expansion during freeze-thaw cycles
A double-start thread engages in a maximum rotation of 180°, thereby facilitating automation

External thread screw caps, automation friendly

Automation friendly options, available in Azenta Life Sciences cap carriers for use with automated capping/de-capping systems
Automation friendly screw caps provide flexibility to use tubes across a range of industry-recognized automated tube handling platforms
Internal thread screw caps, automation friendly
Automation friendly co-molded screw caps for internal thread tubes eliminate the possibility of over tightening
Co-molded caps eliminate the failures in caps using a silicone O-ring
Double start thread engages in a maximum rotation of 180°, facilitating automation
