MALE PELVIS 4 PARTS
This life size model, composed of 4 parts, presents an open view
through a median sagittal section of the pelvis. Internal structures of the male urogeniatl system
are represented in fine detail. The removable parts include a half penis divided into medial and
transverse sections, and half of the male reproductive system with an open dissection of a testis
showing details of the internal structure.

MALE URINARY BLADDER WITH PROSTATE 2 PARTS
This model, enlarged 3 times, shows the male urinary bladder with the
prostate gland surrounding the urethra. The model is dissected medially to expose both
internal and external structures of the bladder and prostate, including the uretheric and
urethral orifices, ductus deferens, seminal gland, ejaculatory duct.

MEIOSIS MODEL
Advantages of Meiosis Models
- Cell components are colour-coded in accordance with educational aspects
- Attaching magnets on the rear • Storage system, free-standing or hanging up.
- Enlarged 10,000 times
The three-dimensional relief model shows the 10 stages of meiosis on the basis of a typical
mammal cell: 1. Interphase (stage of G1-phase)
- Prophase I (leptotene) 3. Prophase I (zygotene and pachytene)
- Prophase I (diplotene) 5. Prophase I (diakinesis)
- Metaphase I 7. Anaphase I
- Telophase I, cytokinesis I, interkinesis, 9. Anaphase II
prophase II and metaphase II 10. Telophase II and cytokinesis II

Chemistry
NaCl Crystal Sodium Chloride Molecular Model
The NaCl crystal or sodium chloride molecular model shows how sodium (Na⁺) and chloride (Cl⁻) ions arrange themselves in a regular, repeating cubic structure, forming a crystal lattice. Each ion is surrounded by six oppositely charged ions, creating a strong, stable ionic bond.
