Cold Block for 1.5 mL Tubes, SBS Footprint, 36 Positions (9×4)

[cat. No. 1068]Cold block for 1.5 mL microcentrifuge tubes (commonly known as "Eppendorf tubes") with an SBS/SLAS footprint for automation compatibility. Holds 36 tubes in a 9×4 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 aluminum body ensures rapid and uniform heat transfer, keeping all 36 tubes at a consistent temperature.Each row features a groove between the tube wells designed to hold the snap-cap of an open tube out of the way. This prevents caps from interfering with pipette tips — especially important when used on a liquid handling robot.The sides of the block have a textured grip pattern 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: 35 mmCapacity: 36 × 1.5 mL tubes (9 columns × 4 rows)Tube well diameter: 11.50 mmWell depth: 33 mmColumn spacing: 14 mm center-to-centerRow spacing: 20.50 mm center-to-centerMaterial: Aluminum (anodized)Compatible with most pipetting robots (that follow SBS standard)

• Holds 36 microcentrifuge tubes — Fits 1.5 mL and 2 mL snap-cap tubes in a 9×4 configuration, keeping all tubes uniformly chilled during temperature-sensitive experiments such as enzyme reactions, ligations, and sample preparation
• 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
• Built-in cap grooves between rows — Each row features a channel designed to hold the snap-cap of an open tube out of the way, preventing caps from interfering with pipette tips during manual or robotic pipetting
• Solid aluminum construction with anodized finish — Provides rapid, uniform heat transfer and excellent thermal inertia so the block stays cold longer than plastic alternatives; the anodized coating resists corrosion from repeated exposure to condensation and common lab chemicals
• Textured side grip for secure handling — Machined grip pattern on both sides ensures a firm hold even when the block is wet or cold; block height of 35 mm keeps tubes at a comfortable working level on the bench or robot deck
