Opening a capped microtube single-handed is a daily friction point in molecular biology — without a fixed tube, the opening motion pushes the tube across the bench. Globe Scientific's 4-Way Microtube Workstation eliminates this with a back-row locking system that holds tubes securely for one-handed cap operation, freeing the other hand for pipetting. The rack accommodates four microtube formats simultaneously — 1.5mL microcentrifuge, 2.0mL microcentrifuge, 0.2mL PCR, and screwcap microtubes — in a single workstation that handles mixed-format protocols without rack changes between steps.
Available in Blue (111780B), Green (111780G), and Red (111780R) at $17.20/EA. Multiple units interlock for larger configurations. Polypropylene construction, autoclavable, made in Slovakia.
Features and Benefits
Back-Row Locking for One-Handed Cap Operation: The back-row retention mechanism clips around the tube body and holds it while the cap is opened or closed with one hand — reducing hand fatigue and speeding up repetitive open/pipette/close cycles in high-volume molecular biology workflows.
4-Way Format Compatibility: 1.5mL microcentrifuge, 2.0mL microcentrifuge, 0.2mL PCR tubes, and screwcap microtubes all supported in a single workstation — no rack switching between protocol steps using different tube formats.
Interlockable for Scalable Configurations: Multiple 111780 units connect together to build a larger linked workstation array for extended sample sets without height or alignment gaps.
3 Colors at Same Price: Blue, Green, Red at identical $17.20/EA — color code by experiment, user, or tube format at no additional cost.
PP, Autoclavable, Made in Slovakia: Chemical-resistant PP with autoclave compatibility for sterile technique biosafety cabinet workflows.

Laboratory Applications
Molecular biology and genomics pipetting stations using multiple microtube formats in the same protocol — PCR setup, extraction aliquoting, and dilution series using 0.2mL, 1.5mL, and 2.0mL tubes without rack changes
High-volume pipetting workflows where back-row tube locking enables single-handed operation to reduce hand fatigue across large sample sets
Sterile technique environments where autoclavable PP workstations are sterilized before use in biosafety cabinets
Frequently Asked Questions
How does the back-row locking work?
A retention clip in each back-row position grips the tube body when seated, holding it against the force of cap opening. Front-row positions are standard open positions. The locking grip is firm enough to hold the tube during one-handed cap operation but releases when the tube is lifted out normally.
Can different colors be linked together?
Yes — all three colors use the same interlock geometry and can be linked in any combination.
