  • In short:

    Enter your DNA/RNA sequence using the included touch screen, USB flash drive or your computer.

    Insert Kilobasers' innovative microfluidic chip & reagent cartridge for DNA/RNA synthesis.

    Press start - within two hours you get your ready-to-use DNA/RNA!

    But a video says more than 39 words:

    How to make DNA yourself with Kilobaser

  • Have a look at our gas supply tutorial, where Alex shows you how to connect a 1 liter argon gas bottle to the push-in connector on the Kilobaser.

    For more detailed information about the gas supply check out our blog post: Gas Supply for Kilobaser.

  • Step 1: Start your DNA synthesis as usual until Kilobaser prompts you to change the reagent cartridge.

    Step 2: Follow these 3 steps which will take you through ‘Reagent Exchange’ process:

    • Release the cartridge

    • Exchange cartridge

    • Press ‘confirm’ to log the cartridge

    By inserting a new reagent cartridge, 20 minutes are added ahead of the actual synthesis to automatically prepare the new phosphoramidites. The DNA synthesis starts automatically as soon as the cartridge is ready for it.

    Note: You can also change the reagent cartridge before the consumption or expiration of an old one.

    Be aware that you can no longer use the old cartridge!

    • To force the cartridge exchange click on the extended options menu at your entered sequence.

    • Select the option ‘Force cartridge change’.

    • Now follow the steps as described above.

    And of course there is a video for you too.

General Information

  • Kilobaser is a desktop DNA/RNA synthesizer. DNA/RNA synthesizers are life science laboratory devices used to print custom DNA/RNA oligos for research, genetic engineering or diagnostic purposes. The DNA/RNA oligos can have any desired nucleotide sequence and artificial chemical modifications such as reporter dyes for DNA probes. The length of the oligos is usually limited from 1 base up to a couple dozen bases.

    Kilobaser, which uses a unique cartridge and microfluidic chip based system, is not just the fastest synthesizer, it’s also specially designed to make DNA & RNA synthesis effortless for any biologist. Our mission is to democratize DNA synthesis and make the technology accessible for any lab.

  • Kilobaser uses a well established chemical synthesis system known as phosphoramidite chemistry and solid-phase synthesis.

    Unique to Kilobaser are two innovations:

    • The cartridge system, where each cartridge holds all necessary reagents for the synthesis. That way DNA & RNA synthesis becomes effortless for every biologist – without any training.

    • The microfluidic chip, which is a consumable containing valves for the liquid reagents as well as the solid-phase, where the growing nucleotide chains are anchored to.

    For more detail, visit our technology page.

  • Independence. Planability. Speed. Security. Scientists can synthesize custom primers by themselves, whenever they want. You know exactly when your DNA is ready to use, no need to hope for the courier to arrive. Faster innovation cycles due to quickly available oligos. This makes it easy to plan experiments ahead. Several iterations can be done on a single day. The customer is able to stay in control of proprietary information as your data stays inhouse.

  • The total liquid volume in each cartridge is just roughly 18mL. The volume of all microfluidic channels in the microfluidic chip is 4µl and thus Kilobaser produces 50% less hazardous waste than usual column-based synthesizers. Per base, the Kilobaser needs 75µL of total liquid volume which will eventually turn to waste. The waste is constantly pumped back into a waste bottle in the cartridge and can be long term stored in there.

    Since the cartridge contains hazardous chemicals, please ensure cartridges are removed in accordance with current regulations in your country.

    Here examples:

    5 oligos with 30 bases

    6 oligos with 25 bases

    7 oligos with 20 bases

  • Depending on the length of your sequence, you get different numbers of oligos out of it.

    Here examples:

    5 oligos with 20 bases

    6 oligos with 16 bases + 4 bases left

    7 oligos with 14 bases + 2 bases left

  • The shelf life of cartridges is one year minimum, and we recommend reagent cartridges be stored at 4°C. After inserted into Kilobaser, the reagent cartridges can be used for up to two weeks or until 150 bases are synthesized. The cartridge should remain inserted into Kilobaser until it is used up.

  • We've shaken up decades of established chemical dna synthesis and advanced the chemicals to eliminate the need for halogenated solvents! At the same time, the system remains compatible with the vast ecosystem of DNA & RNA modifications. Our patented cartridges simplify handling so dramatically that there is no contact with the chemistry. To ensure safe handling, the cartridges are a closed system, even the waste stays in the cartridge! You don't even need to know what's in it! 😉

  • The cartridges must be disposed of as solvent waste.

    We have done our best to make our consumables as environmentally friendly as possible. Therefore, we have developed our DNA & RNA synthesis in such a way that, unlike usual, no halogenated solvents are needed.


  • 'Chip based' means using a small synthetic chip instead of a reagent carrying tubing system, which wastes a big amount of chemicals during operation. This technique is one of the main reasons why Kilobaser saves costs on a large scale. On the one hand you need a lot less reagents and on the other hand you produce a lot less hazardous waste, manufacturing the same amount of DNA as conventional synthesizers.

  • Because the column at which the synthesis starts is integrated into the microfluidic chip, it can only be used once.

  • If stored correctly, the chip has a shelf life of one year.

    The fluidic chips should be stored in the dark at room temperature.

  • Our microfluid chips can simply be disposed of with laboratory waste.

  • Since the number of syntheses possible with one cartridge is not fixed (sequence length dependent), we offer the chips for sale individually.

    You require as many chips as you want to synthesize probes. Since you need a new chip for each synthesis.

DNA Oligos

  • Oligos printed by Kilobaser show a stepwise yield or coupling efficiency of 99.5% is the yield per base. This is comparable to any other manufacturer.

    (Calculation: 0.995 to the power of the number of bases, i.e. for a 20 base primer=0.995^20= 0.9046 yield=yield for a 20 base primer, i.e. 0.9046*100= 90% yield (which means 90% full length product) and 10% are truncated sequences=shorter bases)

  • The total yield is expected to be 300pmol.

    If exact concentration is needed for experiments, we recommend measuring it before with Qubit.

  • The product is a dry DNA of any desired length up to 50 bases.

    Oligos can either be stored dry or resuspended in TE (Tris-EDTA) buffer. Tris-EDTA is a commonly used buffer solution for storing nucleic acids, especially DNA. The buffer keeps the DNA soluble in water and EDTA, a chelator of cations such as magnesium, protects DNA against enzymatic degradation.

    Oligos that are stored at RT or 4°C in TE buffer are more stable than dry oligos. Oligos resuspended in water are the least stable. However, at 4°C, DNA is stable for at least one year under all these conditions. Additionally, it is recommended to store oligos in the dark.

  • The DNA comes out of the machine dry and ready to use and automatic cleavage and final deprotection is performed by Kilobaser. There is no de-salting step involved as our system produces an extremely low amount of salt due to the low total reagent volume used while synthesizing.

  • Primers are eluted from the Kilobaser (ONE/ONE-XT) and are ready to use for most applications, such as PCR/qPCR. After each DNA synthesis, the instrument automatically performs a final deprotection/cleavage step.

    No desalting step is required. Thanks to the lowest possible volume of the microfluidic channels, our system generates minimal salt concentrations. Therefore, we have not yet encountered any applications where these low levels present any problem.

    For highly sophisticated applications sensitive to even trace amounts of salts, such as NMR or crystallography, we recommend purification by means of a size exclusion column or our Kilobaser HIC OliPure Kit. Other specific applications may require HPLC or PAGE purification.After probe synthesis (e.g. 6-Fam), purification of the product is necessary. Apply the Kilobaser OliPure Kit to remove any unreacted dye residue from the sample.

  • Any DNA synthesizer follows the same principle: One nucleotide gets added to the strand at a time. Each step has a certain stepwise yield or error probability, these errors add up the longer the oligo you synthesize is. This ‘stepwise yield (%)’ is typically around 99,5%, leaving 0,5% error rate per nucleotide added. The theoretical total yield can be calculated: 0,995^x = total yield; where x is the number of nucleotides you want.
