Tube Rack 70 – SBS Rack, 70 mm

Tube Rack 70 is the SBS-format base of the 3D-LabEq platform for 1.5/2 mL screw-cap tubes, PCR tubes and mixed tube formats. It stands in a standard deck slot of your Opentrons OT-2 and takes the matching Tube Holders.

Highlights

Takes all matching 3D-LabEq Tube Holders – one rack for many tube formats
Fill with ice beneath the Tube Holder for passive cooling during the run
SBS footprint for a standard deck slot
Colour options for clear coding on the deck

Use on other liquid handlers

Developed for the Opentrons OT-2. On other liquid handlers with an SBS-format deck, you can set up the product as custom labware; this use has not been validated by 3D-LabEq.

Data sheets are available on request – contact us. Custom sizes and other tube formats are also available on request.

Safety note: The supplied JSON labware file does not replace calibration. Before first use, you must calibrate the labware on your Opentrons robot yourself (Labware Position Check). Operation without calibration is at your own risk.
