XL20 & XL9 Tube Handlers for Cool Rooms

Automates re-arraying, sample weighing, volume checking, and data collection for 96 tube sample rack, in a  -4°C  (-10°C for some models) environment

XL20 Tube Handler for Cool Rooms is an automated tube sorter designed to operate inside a cool room or freezer to process samples in a cold environment, and is a cost effective solution for low temperature environments.

Cool room operation allows automated sample tube sorting at -4°C to minimize exposing samples to ambient temperatures.  All XL20 systems operate in same manner where samples are loaded on the deck and processed automatically.

The XL20 for Cool Room is special XL20 hardware configuration with lubricants and components specific for -4°C (and -10°C) environments. The XL20 for Cool Room systems have the same footprint and similar operation to the standard model XL20.
tube handler for freezers and cold rooms

Typical XL20 in cool room configuration

  • XL20 operates inside the cool room typically adjacent to stored samples
  • XL20 and PC may both be located inside cool room 

Typical XL20 in freezer or refrigerated case configuration

  • XL20 is located on freezer shelf or platform
  • XL20’s PC is located outside of the freezer
Case style refrigerators with sliding front doors also provide front access to the XL20. Most lab freezers provide front access to smaller XL9 model and side access to XL20.


  • Sorts / re-arrays sample tubes in 96 tube rack format 
  • Weighs sample tube  (0.1mg readability)
  • Records sample tube 2D ID code & rack ID code
  • Small 28.5” x 21” footprint
  • Water resistant design protects robotics and 2D camera from any effects of condensation

Automation Benefits

  • 20 rack deck capacity provides hours of "walk away" time
  • Sample data output in CSV files for Excel or LIMS 
  • Re-arrays over 500 tubes per hour 


  • XL20 software has pre-set load & go sample processing modes 
  • Work list based software 
  • Worklist, Tare/Gross weighing, & Data collection modes
  • Worklist mode allows re-array of small and large sample sets
  • Software guided deck loading streamlines operation


  • Re-array samples prior to liquid handling
  • Organize tube rack samples for transfer to 384 well plate 
  • Collect sample volume data across compound library
  • Conserve freezer space (consolidate partial racks)

Typically Installed In

  • Compound Libraries
  • HTS Drug Discovery
  • Biobank or Bio repositories
  • Core genomic facilities


Both the XL20 (18-20 racks) and the smaller XL9 (7 to 9 racks) can be configured to operate in cool room and freezer environments. Each instrument can be customized with the features you need in your cool room environment, including:

  • Automated Balance for Volume Detection
  • 2D Barcode Reader

Capacity by Model

  • XL20 with 2D reader (20 rack capacity)
  • XL20 with 2D reader and balance (18 rack capacity)

Optional Add-On

ActiveX Software Developer's Toolkit for integration with other robotic and LIMS systems.
