Description

Thermal Beads (High Purity Aluminum Beads) - Waterless Bath Media | USA Lab

USA Lab Thermal Beads (High Purity Aluminum Beads) are dry, thermal metallic beads designed to replace water in standard-depth, non-circulating and non-shaking laboratory water baths. They can also replace aluminum blocks in dry baths and ice in ice buckets, delivering stable temperature control without evaporation, condensation, or gray water.

Because the beads are dry and naturally more resistant to microbial growth than water, they help reduce contamination risk that can ruin experiments or create safety issues. The smooth, rounded bead shape flows fluidly and conforms to a wide range of vessels—allowing tubes, bottles, and flasks to stay positioned without racks, floats, or bottleneck weights.

With a broad operating range of -80°C to 180°C and high thermal conductivity, bead baths deliver consistent heating or cooling performance while keeping your bath cleaner, safer, and easier to maintain.

Why these USA LAB thermal beads?

Waterless performance — replaces water/ice/oil/sand to reduce fire risk, contamination, and evaporation issues.
Stable temperature control — high thermal conductivity supports consistent heating/cooling from -80°C to 180°C.
Holds vessels in place — beads flow and conform to glassware and tubes; conicals stay upright in <1/2" of beads.
Cleaner lab environment — dry media helps reduce microbial growth and eliminates gray water and daily chemical cleaners.
Saves time & money — no emptying, cleaning, refilling, racks, floats, or bottleneck weights needed for typical use.

FAQ

What are USA Lab Thermal Beads used for?

USA Lab Thermal Beads (High Purity Aluminum Beads) are used as waterless bath media to replace water, ice, oil, or sand in standard laboratory baths, helping provide stable temperature control while reducing contamination and evaporation.

What temperature range can these beads handle?

USA Lab Thermal Beads (High Purity Aluminum Beads) operate across a broad temperature range of -80°C to 180°C, making them suitable for both heating and cooling applications in many labs.

Do I need racks, floats, or weights with a bead bath?

In most cases, no—USA Lab Thermal Beads (High Purity Aluminum Beads) flow and conform around vessels, helping prevent floating or tipping so racks, floats, and bottleneck weights are often unnecessary.

Are these beads compatible with my water bath?

USA Lab Thermal Beads (High Purity Aluminum Beads) are compatible with nearly all non-circulating, non-shallow, standard depth water baths (>5" deep). If you share your bath model, we can help confirm fit and recommend the right volume.
