36 Base Pair DNA-Partially Assembled

SKU: 62122-36U

$1,950.00USD Each


This Indigo® 36 base pair DNA Model is shipped partially assembled. Each base pair is mounted on a support layer & are shipped with its support base & layer separators ready for final assembly. You need only buy the following which should be available in most hardware stores:

North America
2 x 3 foot long, 1/2" diameter threaded rods+coupler to make a 6 foot long support rod.
4 nuts & 4 washers

Outside North America
2 x 1 metre long, 12mm (or 12.5mm) diameter threaded rods+coupler to make a 2 metre support rod. 4 nuts & 4 washers.

Once delivery has been confirmed, we will arrange a mutually convenient time for a Skype or Zoom video chat session with you for final assembly. No experience with molecular modelling is required. Assembly is straightforward & should not take more than 60-75 minutes.

The base pairs are shipped pre-assembled because some of the atom-atom connections are strained & must be glued first. In addition, the assembled model is bulky & incurs very expensive air freight charges for customers outside of North America. The price of this version is slightly less to reflect the cost of the hardware you need to buy has further savings with much cheaper air freight.

Your final assembled model will be identical to the fully assembled 36 base pair DNA model.
