Cold block for 50 mL tubes, SBS footprint, 6 positions (3×2)

[cat. No. 1074]

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.
