Cold Block for 5 mL Tubes, SBS Footprint, 15 Positions (5×3)

Cold block for 5 mL centrifuge and snap-cap tubes with an SBS/SLAS footprint for automation compatibility. Holds 15 tubes in a 5×3 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. The solid aluminum mass provides excellent thermal inertia — once chilled, the block keeps tubes cold significantly longer than plastic racks or ice buckets, with uniform temperature across all 15 positions.The wells feature a countersunk entry with a conical profile that matches standard 5 mL centrifuge tubes, maximizing contact area for efficient heat transfer and making it easy to insert tubes with one hand.The sides feature a textured grip area for easy and secure handling, even when wet or cold.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.Technical specifications:SBS (SLAS/ANSI) footprint: 127.76 × 85.48 mmHeight: 48 mmCapacity: 15 × 5 mL tubes (5 columns × 3 rows)Well diameter: 18 mmWell depth: 46 mmTube spacing: 26 mm center-to-centerMaterial: Aluminum (anodized)Compatible with most pipetting robots (that follow SBS standard)

• Holds 15 tubes in a compact format — Fits standard 5 mL centrifuge and snap-cap tubes in a 5×3 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
• Solid aluminum construction with excellent thermal inertia — At 48 mm tall with 15 deep wells, the block retains cold effectively for extended procedures such as small-volume extractions, aliquoting, and enzymatic reactions where maintaining consistent low temperature is critical
• Countersunk well entry for easy one-handed tube insertion — Each well features a chamfered opening that guides the tube into position, making it quick to load and unload even while holding a pipette in the other hand
• Textured grip for secure handling — Machined grip pattern on both sides ensures a firm hold even when wet or cold; anodized finish resists corrosion from repeated exposure to condensation, ice baths, and common lab chemicals
