DNA (Helical) Models
DNA (Helical) Models (Product Code: SCL217/0129) is a PVC double-helix model used to show how the DNA molecule is built in genetics and molecular biology lessons. Students assemble and study its mountable parts to see two strands coiled around each other, with the bases inside and the sugar-phosphate backbone outside. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

| Parts | Mountable |
| Material | PVC |
| Colouring | Non-toxic dyes |

| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the DNA Helix Model Used For?
Textbook diagrams flatten DNA onto a page; a physical helix shows how the two strands wind around a common axis and why the bases end up protected on the inside. Teachers use the DNA (Helical) Models to explain base pairing across the cross bars, the repeating sugar-phosphate backbone, and how the molecule can unzip for copying.
Because the parts are mountable, the model doubles as a hands-on DNA model kit for small groups: learners build a section, then check it against the finished helix. It is a good fit for genetics, cell biology and biotechnology units in senior school and first-year college courses.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM of the DNA (Helical) Models. The model is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools and distributors buy it at source rather than from a reseller. Visit the ScienceLab profile to learn about the company.
If a small mountable part goes missing over several school years, ask us about a replacement; requests are handled by the manufacturer that made the model.

Frequently Asked Questions
What structure do the DNA (Helical) Models show?
The DNA (Helical) Models show the double helix: two long parallel strands coiled around each other and joined by short cross bars at regular intervals. The bases face the inside of the helix, while sugar and phosphate units form the backbone on the outside.
Do the DNA (Helical) Models have to be assembled?
The DNA (Helical) Models have mountable parts, so the helix can be put together and taken apart for teaching. How the model is delivered, assembled or partly assembled, is not listed; ask us when you request a quotation.
What are the DNA (Helical) Models made from?
The DNA (Helical) Models are made of PVC coloured with non-toxic dyes, which suits repeated handling by students. Keep the parts in a box between lessons, clean them with a damp cloth, and avoid storing them near heat.
Who manufactures the DNA (Helical) Models?
The DNA (Helical) Models are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, dealers and importers receive quotations and after-sales answers directly from the manufacturer.
How many base pairs or colours do the DNA (Helical) Models use?
The number of base pairs, the overall height and the colour code of the DNA (Helical) Models are not stated in the listing. Contact us for these details and a photograph before finalising an order for your genetics lessons.
Can the DNA (Helical) Models be ordered for a whole school system?
Yes. The DNA (Helical) Models can be quoted in bulk for school networks, colleges, dealers and importers across India and international markets. Send the quantity and delivery details via the contact page for a combined quotation.
