How They Work
The Manual Microtome YR421 operates using a manually adjusted microtome mechanism which ensures consistently thin sections of specimens. Its precise hand-wheel system, constructed to minimize variability, ensures that each rotation results in incremental and reliable sectioning.
In contrast, the Rotary Microtome HM 325 uses a rotary wheel to bring about the slicing of specimens. This method promotes uniform thickness with successive rotations, allowing users to maintain consistency throughout numerous samples. The user interface is designed to facilitate quick adaptations to different sample requirements.
What It’s Used For
The Manual Microtome YR421 is primarily used in histopathology labs to prepare thin tissue sections suitable for microscopic evaluation. This precision tool is essential for producing slides required for diagnosis and medical research. Its ability to generate repeatedly thin and precise sections makes it invaluable in settings where high quality is non-negotiable.
Types
Microtomes come in various types, including rotary, sled, and vibrating microtomes. The Manual Microtome YR421 from Kalstein is a manual type, which is ideal for educational and professional settings requiring precision control over each section. Meanwhile, automated and semi-automated varieties are available for high-throughput laboratories needing enhanced efficiency.
Market Price
The pricing for manual microtomes like the YR421 and HM 325 can vary. The Manual Microtome YR421 from Kalstein is cost-effective, offering high-quality performance without compromising on budget. Prices typically range between $2,500 and $5,000, depending on the features included and additional accessories purchased.
Frequently Asked Questions
What is the standard thickness range for sections using these microtomes?
Both the Manual Microtome YR421 and the Rotary Microtome HM 325 allow for a standard thickness range of 1 to 60 microns, providing the flexibility required for various sample preparations.
How often do microtome blades need to be replaced?
The frequency of blade replacement depends on usage frequency and the hardness of the material being sectioned. Typically, frequent users might change blades weekly, while less frequent users may do so monthly.
Advantages and Disadvantages
The Manual Microtome YR421 excels in affordability, precise control, and user comfort, making it a preferred choice for many laboratory environments. Its manual operation is advantageous for consistency in application. However, it may require more effort than automatic versions, making it less suitable for high-throughput labs.
On the other hand, the Rotary Microtome HM 325 is seen as highly durable with a reputation for reliability. Nevertheless, its higher cost and manual cleaning requirement might pose challenges for budget-conscious or time-poor laboratories.
Field Use of Products
In practice, both microtomes are utilized extensively in hospital labs, research institutions, and educational settings. The Manual Microtome YR421 is particularly favored for its precision control in smaller labs where individual sample assessment is critical. Its sturdy build allows for repeated and rigorous use without degradation in performance.
Recommendations
For optimal performance, it’s recommended to regularly clean the blade holder and perform routine maintenance on the hand-wheel mechanism of the Manual Microtome YR421. This can prolong the equipment’s lifespan and ensure continuous accuracy. Users are encouraged to use the Kalstein platform to explore comprehensive service options and spare parts availability, ensuring their microtome remains in top condition.
