It is our honor to ceremoniously introduce the CommaVac™ vacuum manifolds.

CommaVac™ vacuum manifolds are designed specially for nucleic acid purification and suitable for 96-well plates and spin columns, facilitating purification of plasmid DNA, genomic DNA, viral nucleic acid and PCR products, etc.

96-Well Plate Mode

CommaVac™ vacuum manifolds offer 96-Well plate mode, for:

  • Lysis filtration and nucleic acid binding with 96-well plates
  • Washing with 96-well plates
  • Elution with 96-well plates

Spin Column Mode

CommaVac™ vacuum manifolds offer spin column mode, with up to 8 columns, for:

  • Washing with spin columns
  • Elution with spin columns

Handy Tools for Easier Use

CommaVac™ vacuum manifolds are designed to simplify the procedure of nucleic acid extraction to avoid tedious repeated pipetting, centrifugation, and solution transferring commonly seen in life sciences labs.

The purified DNA can be easily eluted and collected by connecting a collection tube or 96-well plate to the vacuum manifold.

CommaVac™ vacuum manifolds are made of corrosion-proof materials. Its compact and firm design ensures the uniform flow rate, excellent stability and good reproducibility during vacuum extraction process.


Rose Red and Sapphire Blue, Two Colors Available

In addition to fast and reliable results, CommaVac™ vacuum manifolds come with fashionable colorful style, instead of grey appearance you see in traditional lab equipment, bringing you a relaxed and comfortable experiment experience.

We now offer rose red and sapphire blue variants for you.

Rose red means romance and passion.

Sapphire blue means intelligence and preciseness
