Product Details

QIAGEN QIAvac vacuum systems enable fast and efficient vacuum processing of up to 24 spin columns using the QIAvac 24 Plus, of 96-well plates using the QIAvac 96 and up to 6 HiSpeed Mega or Giga Columns using the QIAvac HiSpeed LS Vacuum.

For optimal results, we recommend using the QIAvac 24 Plus and QIAvac 96 together with the QIAvac Connecting System and a Vacuum Pump. The QIAvac 24 Plus must be used together with the QIAvac Accessories. For optimal results, we recommend using the QIAvac HiSpeed LS together with a Vacuum Pump.


Vacuum-driven liquid processing is faster than centrifugation and still gives high, reproducible yields (see figure  "High, reproducible yields of genomic DNA").

See figures


QIAvac vacuum systems are for vacuum purification using QIAGEN spin kits. Vacuum-driven liquid processing facilitates sample handling and reduces hands-on preparation time by eliminating the tedious loading and unloading of spin columns into a centrifuge and subsequent removal of flow-through during binding and washing procedures (see flowchart  "Vacuum-driven liquid processing on vacuum manifolds"). Preventing cross-contamination is especially critical when purifying nucleic acids from sensitive samples. To overcome this, QIAGEN columns are inserted into disposable VacConnectors, preventing direct contact of the column with the manifold. VacValves ensure constant vacuum pressure. With the QIAvac HiSpeed LS, the sample flow-through, containing possible infectious material, is collected in separate waste bottles. In combination with the QIAvac Connecting System (vacuum connecting system) (see figure  "An integrated system for various applications"), the QIAvac 24 Plus can be used as a flow-through system. The sample flow-through, containing possible infectious material, is collected in a separate waste bottle.

For vacuum processing in 96-well format, the 96-well purification plate sits in the QIAvac 96 top plate, allowing samples and buffers to be efficiently drawn through the wells. The QIAvac 96 base holds an additional module, a waste tray, or collection vessels such as Collection Microtubes or a 96-well microplate during processing. This allows samples to be drawn from one module to the next, avoiding time-consuming labeling and transfer steps.

See figures


Simply insert 1–6 columns into the QIAvac HiSpeed LS or 1–24 columns into the QIAvac 24 Plus, add the samples or buffers and turn on the vacuum source (see table “Examples of plasmid kits that can be used with the QIAvac 24 Plus”). For high-throughput vacuum processing using the QIAvac 96, place the waste tray inside the QIAvac base, then place the QIAvac 96 top plate squarely over the QIAvac base. Simply place a QIAGEN 96-well purification plate in the QIAvac 96 top plate, making sure that the plate is seated tightly and turn on the vacuum source. Samples and buffers are drawn efficiently through the columns or wells, facilitating multiple loadings of large sample volumes and eliminating the need to discard flow-through.

The two protocols given below are for the use of the Ni-NTA Superflow 96 BioRobot® Kit in manual procedures. The kit has been specially designed and optimized for automated 6xHis-tagged protein purification on QIAGEN® BioRobot Systems. For more details of the advantages of BioRobot Systems see the Ni-NTA Superflow 96 BioRobot Kit Handbook supplied with the kit or contact one of the QIAGEN Technical Service Departments or local distributors listed on the last page of the handbook.
User-Developed Protocols (2)
This procedure has been adapted by customers and is for purification of viral RNA and DNA from plasma, serum, and cell-free body fluids using the QIAamp MinElute Virus Vacuum Kit.
The procedure has been used successfully for isolation of a single-copy, 14.5 kb, binary plasmid, p35S GUS INT, from Agrobacterium tumefaciens strain GV2260 (1).


Can the QIAvac 96 vacuum manifold be used with DirectPrep 96 plates?

No. The DirectPrep 96 plate of the DirectPrep 96 Miniprep Kit cannot be securely positioned in the QIAvac 96 vacuum manifold, and the nozzles may not fit into the correct wells below. Furthermore, adapters are needed to position Elution Microtubes or Microplates in the correct height for elution. If the distance of the "receiving" plate to the nozzles is not optimal, splashing and thus cross contamination can occur. Due to these difficulties with fitting, tightness and potential cross contamination, we do not recommend using the QIAvac 96 with the DirectPrep 96 System.

We recommend to use the QIAvac Mulitwell vacuum manifold in combination with the DirectPrep 96 Miniprep Kit.
