Sealed with plunger and luer lock — prevents resin drying
Resin stays hydrated — enabling up to 10 reuse cycles
Buffers flow gently across functional groups for clean performance
Ideal for labs seeking long-term cost efficiency

Conventional Methods
-
Single-use. (spin, beads, tips)
-
Centrifuges, magnets, or pumps needed
-
Beads/columns often discarded after use
-
Full buffer control via plunger
-
Linear flow only, less efficient
How DTG Syringe Columns Work
DTG’s syringe columns combine high performance with low cost by using fully manual, back-and-forth flow.
No equipment, no waste, and no resin degradation.
FAQ
An affinity column embedded in a syringe barrel, using controlled plunger pressure for uniform flow and binding.
The plunger seals the top; a luer lock seals the base—no air exposure = no drying = multiple reuses.
The hydrated resin maintains function between runs. Regeneration and cleaning buffers restore it up to 10×.
Currently IMAC and ProA.
Back-and-forth plunger flow allows true equilibrium, improving yield in fewer steps.
It’s faster, more intuitive, and cost-effective—with better control over each buffer exchange.
