T.S Blastula
T.S Blastula (Product Code: SCL451/0174) is a prepared transverse section of a blastula, the hollow ball of cells formed after early cleavage, used to teach the first embryonic stage with an internal cavity in embryology practicals. Developmental biology students use it to locate the blastocoel and compare cell sizes across the embryo. The slide is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for school and college laboratories, in a white plastic box.

What Is the T.S. Blastula Slide Used For?
Students first locate the round outline of the embryo at low power, then identify the blastoderm — the layer of blastomeres surrounding a fluid-filled cavity, the blastocoel. In embryos that develop from yolky eggs, such as those of amphibians, the cavity is pushed towards the animal pole where the cells are small, while larger yolk-laden cells crowd the vegetal side; in eggs with little yolk the cavity is more central. Deciding which pattern their own section shows is a good observation exercise.
In the teaching sequence the blastula sits between the solid morula and gastrulation, when cells move inwards to form the germ layers. Showing the morula and blastula slides one after the other makes the appearance of the cavity obvious, and an embryology stages chart helps students place both in context. Drawing the section with the poles and the blastocoel labelled is a common practical-record task, and the slide is a standard part of any school biology lab setup that covers animal development.

Frequently Asked Questions
What is the difference between a blastula and a morula?
The T.S Blastula slide shows a hollow ball of cells enclosing a fluid-filled cavity, the blastocoel, whereas a morula is a solid cluster of blastomeres with no cavity. That difference is the main thing students look for on this slide.
Which animal’s embryo is used?
The species used for the T.S Blastula slide is not given in its product information. Please contact us to confirm before ordering if your syllabus names a specific animal, such as an amphibian, for embryology practicals.
Does every section show the blastocoel clearly?
A transverse cut through a blastula, as on the T.S Blastula slide, is intended to pass through the blastocoel, but the exact appearance differs slightly from one section to the next, as it does with any biological slide.
Is a storage box included?
Yes. The T.S Blastula slide comes in a white rectangular plastic box. The number of slides per box is not listed in the product information, so please confirm the quantity you need when you enquire.
Who supplies the T.S Blastula slide?
The T.S Blastula slide (SCL451/0174) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. Its CIN and GSTIN are given in the Supplier section for institutional vendor registration.
How should students handle the slide?
Carry the T.S Blastula slide flat, hold it by the edges and always start focusing with the low-power objective so the lens cannot strike the glass. Return it to its box straight after use to protect the section.
What details help us prepare a quotation?
For a quotation on the T.S Blastula slide, send the product code SCL451/0174, the number required, the delivery location and the date you need it by. Schools and colleges in India and international markets are supplied.
