Cold Block for 50 mL Tubes, SBS Footprint, 6 Positions (3×2)

Cold block for 50 mL conical centrifuge tubes (Falcon-type) with an SBS/SLAS footprint for automation compatibility. Holds 6 tubes in a 3×2 configuration.Pre-chill the cold block in a freezer or on ice and use it instead of an ice bucket for experiments that require low temperatures. With nearly solid aluminum construction and only six wells, this block has the highest thermal mass in the lineup — once chilled, it maintains temperature exceptionally well, keeping your 50 mL tubes uniformly cold for extended procedures.The wells are precision-machined with a conical profile that matches standard 50 mL centrifuge tubes, maximizing the contact area between the tube wall and the aluminum for efficient heat transfer.The sides feature a textured hand-grip area for easy and secure handling. Given the block's considerable weight, this grip texture is not a luxury — it is a necessity. The block also doubles as a premium-grade paperweight, a conversation starter, or a reliable stress-relief device after a long day of unsuccessful experiments. Some researchers have noted that its solid construction provides a reassuring sense of security when working late nights in the lab.The cold block has an SBS footprint and will fit any pipetting robot that follows the "Society for Biomolecular Screening" standard. This standard is also known as SLAS/ANSI form factor.The block's substantial weight also makes it surprisingly versatile beyond thermal management. It can serve as a premium-grade paperweight, a conversation starter, or a reliable stress-relief device after a long day of unsuccessful experiments.

• Holds 6 conical centrifuge tubes — Fits standard 50 mL Falcon-type tubes in a 3×2 configuration with precision-machined conical wells that match the tube profile, maximizing wall contact for efficient and uniform heat transfer
• Automation-ready SBS footprint — Dimensions follow the Society for Biomolecular Screening standard (127.76 × 85.48 mm), compatible with liquid handling robots from Opentrons, Hamilton, Tecan, Beckman, Agilent, Integra, and others
• Highest thermal mass in the lineup — With only six wells bored into a nearly solid aluminum block, this is the densest cold block in the collection; once chilled, it maintains temperature exceptionally well for extended procedures such as media preparation, buffer storage, large-volume extractions, and cell culture workflows
• Textured hand-grip area is essential, not optional — At 97 mm tall and built from nearly solid aluminum, this is the heaviest block in the series; the machined grip pattern on both sides provides a firm, secure hold even when wet or cold, because dropping this one on your foot will be memorable
• Anodized aluminum built to last — Corrosion-resistant finish withstands repeated exposure to condensation, ice baths, and common lab chemicals; the block's formidable heft also earns it a place as the undisputed champion of lab paperweights and the most persuasive conversation-ender on any bench
