Tube Gripper
Pneumatic tube grippers for 8 mm to 35 mm diameter tubes and bottles. Pressure-controlled grip force and adjustable finger length — one module for pick-and-place, capping, and decapping of both screw caps and push caps.
Available in two sizes — Small for 8 – 16 mm and Large for 16 – 35 mm — covering the full range of common lab tubes from a single mounting interface.
See it in action
8 – 16 mm diameter
Built for the tubes that fill most molecular biology and clinical workflows — 1.5 mL and 2 mL microcentrifuge tubes, cryovials, and small screw-cap sample tubes. Lower the input pressure for delicate caps and thin-walled tubes; raise it when you need a firmer hold for capping or decapping. Adjustable finger length lets the gripper reach into deep racks and cryo storage without the arm fouling on adjacent tubes.
16 – 35 mm diameter
Designed around the heavier, larger labware that the small gripper can’t reach — 15 mL and 50 mL conicals, reagent and media bottles, and bulk-storage containers. Same pressure-controlled actuation and adjustable fingers as the small gripper, scaled up to handle a full 50 mL conical through fast moves without slip. Swap between the two grippers on the same mounting interface to cover your entire workflow without redesigning the cell.
