Eisco Prepared Microscope Slides – Onion Root Tip Mitosis Pack of 10

Description

Product Overview

The Eisco Prepared Microscope Slides set is a meticulously curated collection of ten onion (Allium cepa) root tip specimens, each mounted on a standard 75 mm × 25 mm × 0.06 in slide. These slides are engineered to reveal the complete sequence of mitotic stages—prophase, metaphase, anaphase, and telophase—under a compound microscope with 400× to 1000× magnification. Every slide is pre‑stained with a reliable, non‑toxic dye that accentuates chromosomal structures while preserving cellular integrity. The slides are sealed with an inert cover slip, labeled with the corresponding mitotic phase, and packaged in a rugged, reusable case that protects against breakage, moisture, and dust. Dimensions of the entire package are 3 × 1 × 0.13 inches, weighing only 0.16 oz, making it easy to transport between classrooms, labs, or field stations. Manufactured by Eisco, a trusted name in scientific education supplies, this product meets the rigorous standards required for high‑school and undergraduate biology curricula.

Usage

These slides are designed for immediate integration into any biology or life‑science instructional setting. In a high‑school classroom, teachers can demonstrate the dynamic process of cell division by guiding students through each mitotic phase, reinforcing concepts of genetics, growth, and development. At the undergraduate level, the slides serve as a baseline for comparative studies, allowing students to contrast plant mitosis with animal cell division or to explore the effects of chemical inhibitors on chromosome behavior. The slides are also valuable for laboratory technicians who require consistent, reproducible specimens for calibration of microscope optics or for training new personnel in slide handling techniques. Because the slides are pre‑labeled, they eliminate the need for time‑consuming preparation, enabling educators to allocate more class time to discussion, analysis, and experimental design. The protective case ensures that the slides remain intact during field trips, outreach events, or when stored for long‑term use.

Why Choose Us

Eisco’s commitment to quality begins with the selection of premium onion bulbs harvested at the optimal growth stage to guarantee a high mitotic index. Each root tip is carefully trimmed, fixed, and stained using a standardized protocol that minimizes variability between slides. The result is a uniform visual experience that supports accurate observation and data collection. Our slides undergo a double‑seal process that prevents evaporation and protects the specimen from contamination, extending shelf life well beyond the typical classroom year. Additionally, Eisco provides a 30‑day satisfaction guarantee and responsive customer support that can assist with troubleshooting, replacement requests, or educational resources such as lesson plans and activity guides. By choosing this product, educators invest in a reliable teaching tool that aligns with curriculum standards and promotes scientific literacy.

FAQ

What microscope magnification is required to view the mitotic stages clearly?

The slides are optimized for 400× to 1000× total magnification, which is typical for most compound microscopes used in secondary and post‑secondary education. At 400×, the overall cell structure and chromosome arrangement become visible, while 1000× provides detailed views of individual chromatids during anaphase and telophase.

Are the slides safe for use by students of all ages?

Yes. The staining chemicals used are non‑hazardous and the slides are sealed with an inert cover slip, preventing direct contact with the specimen. Nevertheless, standard laboratory safety practices—such as wearing gloves and eye protection—should always be followed.

How long can the slides be stored without degradation?

When kept in the supplied protective case, away from direct sunlight and extreme temperature fluctuations, the slides retain their staining quality and structural integrity for at least three years. The sealed environment prevents moisture ingress, which is the primary cause of degradation in microscope specimens.

Can these slides be used for quantitative analysis, such as counting chromosome numbers?

Absolutely. Because each slide presents a clear, consistent view of the chromosomes at each mitotic stage, students and researchers can reliably count chromosome numbers, measure spindle lengths, or assess the effects of experimental treatments on cell division dynamics.

Do you offer any supplemental teaching resources?

Eisco provides downloadable lesson plans, activity worksheets, and video tutorials that align with national biology standards. These resources are free for educators who purchase the slide set and can be accessed through the Eisco website using the product’s model number BS18002PK10.
