DNA (Double Helix)
DNA (Double Helix) (Product Code: SCL525/0238) is a plastic model of the DNA double helix used to show how two strands wind around a common axis in genetics and molecular biology lessons. Measuring 10 x 10 x 45 cm, it gives higher secondary classes and first-year college students a finished structure to turn and examine alongside any DNA model kit they build themselves. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the DNA Double Helix Model Used For?
Rotating the model slowly in front of the class makes the helical twist obvious in a way no textbook drawing can. From there the teacher can explain the main features of the Watson and Crick structure: a sugar-phosphate backbone runs along the outside of each strand, the bases pair across the middle (adenine with thymine, guanine with cytosine), the two strands run in opposite directions, and the twist creates a major and a minor groove along the molecule.
The same model helps with replication, since students can picture the strands separating so that each one acts as a template, and with the idea that a gene is simply a stretch of base sequence. When a class builds its own DNA from a kit, this finished helix is the reference to check their work against. Dust it with a dry, soft cloth and keep it where it will not be knocked over.
OEM Manufacturer
The DNA (Double Helix) model is manufactured by Jain Scientific Equipments Private Limited, which does business as ScienceLab and is the model's OEM (original equipment manufacturer). It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and reaches schools, colleges, dealers and importers factory-direct, with quotations issued by the manufacturer rather than by a middleman. Our company profile describes the company and its range.

Frequently Asked Questions
What are the dimensions and material?
The DNA (Double Helix) model measures 10 x 10 x 45 cm and is made of plastic, a tall, slim format suited to desk-top demonstration in front of a class or display in a biology laboratory cabinet.
Are the bases shown in different colours?
Colour coding of the bases is not described in our current product details for the DNA (Double Helix) model. Please contact us for photographs or a description if colour-coded base pairs matter for your lessons.
Does it arrive assembled?
Assembly details are not stated in our listing for the DNA (Double Helix) model. We will confirm whether it arrives assembled or needs fitting together when we send your quotation, so mention it if this matters for your class.
Which classes is it suited to?
The DNA (Double Helix) model suits genetics and molecular biology chapters in higher secondary school and introductory college courses, where students must describe the double-helix structure, base pairing and the basis of DNA replication.
Who manufactures the DNA (Double Helix) model?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the DNA (Double Helix) model as the OEM at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to schools, colleges, dealers and importers.
How should the model be looked after?
Keep the DNA (Double Helix) model dust-free with a dry, soft cloth, avoid placing it near heaters or in strong sunlight, and store it where it will not be knocked over between lessons.
Is bulk supply possible?
Yes. The DNA (Double Helix) model can be supplied in quantity to schools, colleges and distributors in India and international markets; send the number of units and the delivery location for a quotation from the manufacturer.
