Salt Free Oligos - Pure DNA. No extras.
Order Salt Free Oligos for PCR, cloning and Sanger sequencing
Salt Free oligos are short strands of synthetic DNA without any chemical modifications – pure, simple, and ready to use.
“Salt-free” means the oligos are cleaned from residual salts and synthesis byproducts, giving you just what you need: clean DNA for your experiment.
They’re ideal for standard applications like PCR, cloning, or Sanger sequencing – when you just need reliable primers without any extras.
ISO 9001 / 13485
Chosen by 1400+ European labs in 2024
No-frills. No nonsense. Just pure DNA.
Order today. Get your oligos tomorrow.
Fast turnaround. No surprises. Just pure DNA.

Product Specifications
Synthesis and postprocessing in ultra high throughput.
Make use of a NightXpress delivery by placing your SaltFree Oligo order before 9:00 am CET
Minimum and average yields (OD) per scale and length:
Typical yield and purity applies to a 20mer; Calculation: 1 OD = 5 nmol = 30 μg; may vary for individual dyes, sequences with GC content > 70%, > 3 purine stretches, or strong secondary structures.
The synthesis scale indicates the initial amount of 3' bases; There is no OD guarantee for oligos < 18 and > 35 bases.
Click. Done.
