Relaunch announcement

FloteTech is back

For years, the FLOTE-TECH Model A set the standard for water-based separation and recovery in the field and the lab. Today RJ Dausman Technical Services is proud to announce the relaunch of FloteTech and a new production run of the Model A. If your work depends on recovering artifacts, fossils, charcoal, or invertebrate remains from soil and sediment, we're building this machine for you — and we'd like to hear from you first.

Separation and recovery with water and diffused air

The FLOTE-TECH Model A is a portable, two-mode flotation system that processes soil and sediment samples rapidly in a closed system — in the laboratory or in the field, even where no water supply is available.

100 gal Closed water system — reduced water usage cuts recovery expenses
20 L Maximum sample capacity processed in a single run
Lab + field Fully portable — works where there is no available water

What the Model A does

Soil and sediment samples are processed by a high-efficiency, two-mode process using water and diffused air. Light fractions float free while heavy fractions settle, letting you recover fragile evidence quickly and gently.

  • Recovers artifacts, fossils, invertebrate life forms, charcoal, and other evidence
  • Closed system requires only 100 gallons of water — rapid processing at lower cost
  • Dispersing agents can be used in the system and continuously recycled
  • Accommodates samples up to 20 liters
  • Portable design for laboratory or field use, including sites with no water supply

Built for your work

Archaeology

Flotation of charcoal, seeds, and micro-artifacts from excavation samples on site or in the lab.

Paleontology

Gentle recovery of fossils and small vertebrate remains from matrix and sediment.

Environmental science

Separation of invertebrate life forms and organic evidence from soil and sediment cores.

Frequently asked questions

When will units be available?
We're finalizing the new production run now. Registering your interest puts you in line for early availability updates and delivery scheduling — there's no obligation.
Does registering interest commit me to a purchase?
No. This form simply tells us you'd like to be contacted about acquiring a unit. We'll follow up with pricing, availability, and specifications.
Can the Model A really run without a water supply?
Yes. The closed system requires only 100 gallons of water, which is continuously recycled — so the unit can operate in the field where no water is available.
What size samples can it handle?
The Model A accommodates samples up to 20 liters and processes them rapidly using its two-mode water and diffused-air system.
