Smarter DNA/RNA preparation kits by INVITEK


The Invitek sample preparation kits are outstanding because of their advanced production process. The quality of the products is exceedingly high, resulting in the following advantages for you:

  1. Save time with shorter RNA and DNA purification protocols
  2. Higher DNA yield by longer enzymatic activity for sample lysis
  3. More intact DNA – less chemical degradation

Sample collection and preservation of Saliva, Swabs, and Stool 

It is important to guarantee high-quality samples for getting excellent results. Our non-invasible collection tubes for DNA Samples:

  • Cost saving: avoid cooling, eliminate costs associated with shipping and temperature control. 
  • Easy and intuitive use
  • Reliable results: Minimise bias by microbial growth 

Our sample collection and stabiliser kits enables long-term stability of DNA in stool samples (up to 105 days), in saliva samples (up to 1 year).

INVISORB - Spin Soil DNA kit 

Save time with our kit because of its short protocol. The kit enables DNA isolation from microorganisms in soil samples. The technology used is spin column technology. 

For more information, you can have a look at the brochure. 

DNA Clean Up 

Our DNA Clean-up is an easy-to-use kit for routine molecular biology applications. 

  • Save time: 7 min protocol for cleaning up PCR and enzymatic reactions (MSB Spin PCRapace) and 20 mins for DNA fragment clean-up from agarose gels (Invisorb Fragment Clean-up)
  • 95% recovery of fragment sizes between 80 bp and 30 kb.

We do also offer sample preparation for infectious diseasesnucleic acid extraction kits for infectious diseases. 


  • Purification of microbial DNA by combining Stool Collection tubes with DNA stabiliser kits: Read the application note here for combination with Zymo kits, and here for Qiagen kits.

InviMag technology

Magnetic beads for DNA/RNA sample preparation - Preparation on KingFisher Systems 


The InviMag magnetic beads are developed and selected for optimal performance in a variety of applications. Based on the application, sample characteristics and instrument platform used, Invitek Molecular selects the InviMag beads best suited for each particular purpose. 

  • Fast magnetic velocity via high magnetic content (70–90 % of iron oxides)
  • A variety of binding capacities through different-sized beads (200 nm–1 µm)
  • Excellent reproducibility and stability through uniform size distribution
  • Superior suspension stability
  • Application fields: Cancer genetics, Genotyping, Plant genotyping, GMO analysis, Pathogen Detetion, Gene Expression Analysis and Cloning experiments. 


  • Fully automated processing on InviGenius PLUS starting from DNA
  • Standardised walk-away workflow starting from blood, FFPE or plasma sample to bisulfite conversion of the isolated DNA on the instrument possible
  • Only 10 min hands-on time

For example The InviMag® Bisulfite Conversion

The InviMag® Bisulfite Conversion Kit/ IG features a fully automated and reliable bisulfite treatment and conversion of cfDNA and genomic DNA from whole blood, cell cultures, tissue samples and FFPE slides for methylation analysis. The process is fully automated on the InviGenius® PLUS and can be combined with previous protein, DNA and RNA extraction workflows on the instrument.

RTP Technology – Ready to prep

The RTP technology is based on the patented non-chaotropic chemistry Invitek is using. With this technology nucleic acids are able to bind in very low salt concentrations which reduces the amount of wash steps in the DNA and RNA isolation process and thereby leading to faster protocols.  

MSB Technology – Minimal salt binding 

MSB products will purify DNA from reaction mixtures like PCR, cDNA synthesis, restriction enzyme digests or other enzymatic reactions. DNA fragments from 80 bp to 30 kbp are recovered with very high yields in a final elution volume as low as 10 µl.

Range of products

A full range of priotein, DNA and RNA purification products and formats, more than 120, for your DNA/RNA application demands. A wide selection of products for high-throughput and automated sample processing. Many products are developed and manufactured in compliance with the Directive 98/79/EC on in vitro diagnostic medical devices (IVD-Directive).

DNA/RNA and Protein purification by QRET Technologies


Purification solutions                                     

By moving particles, not liquids, the QuickPick™ method offers a clear advantage over conventional protein, RNA and DNA isolation methods. Using the QuickPick method, your nucleic acid and protein purification method is faster, simpler and gentle from different sample sources: plants, human tissue, animal tissue, etc. 

Magnetic DNA and RNA purification

Magnetic protein, DNA and RNA extraction is built on the affinity on the surface of magnetic particles. A suspension of magnetic particles is mixed with a preparation of the target molecule. Once the target is bound to the group, a magnet is used to separate the target-bound particles from the solution. The unbound material can then be washed away from the particles. Depending on the application, the target molecules can, if necessary, be separated from the magnetic particles.

Magnetic particle technology has several advantages

  • Fast and simple
  • More economical as other separation methods as centrifugation and vacuum DNA, RNA and protein extraction and softer on the sample. 
  • Less contamination because of moving particles instead of liquids. 

QuicPick™ tools

  • QuicPick™ 1-magnet tool
