Introduction
A manual microtome is a precision instrument used to cut thin sections of specimens, typically biological tissues embedded in paraffin, for microscopic examination, and it is operated entirely by hand, and it is used in histology, pathology, and research laboratories. The manual microtome consists of a specimen block holder mounted on a mechanism, a blade holder, and a handwheel; the operator rotates the handwheel to advance the specimen block past the blade, cutting a section of a preset thickness, typically 1-10 micrometers, and the block is advanced by a micrometer mechanism for each section, and the operator controls the sectioning by hand, with the section thickness set by adjusting the micrometer; the manual microtome is simple, reliable, and economical, and it provides precise sections with the skill of the operator, and the sections are transferred from the blade to a water bath and mounted on slides. Manual microtomes are used for cutting paraffin-embedded tissue sections for histopathological diagnosis, for preparing sections for staining and examination, for research, for teaching, and for many other applications, in hospital pathology laboratories, research institutions, and teaching laboratories, and they are available in various designs, including rotary and sliding models, with features such as precise thickness adjustment, specimen orientation controls, and a robust construction. With their simplicity and precision, manual microtomes are essential instruments for tissue sectioning, especially in laboratories where a basic and economical instrument is required.

FAQ
Q1: What testing scenarios is this microtome mainly applied to?
A: The manual microtome is used in pathology laboratories, histology facilities, educational institutions, clinical diagnostics and research to perform precise hand-operated sectioning of fixed, paraffin-embedded tissue samples for microscopic examination, histopathological diagnosis and educational purposes. It supports routine histopathology sectioning for diagnosis, educational histology teaching, clinical pathology, research tissue sectioning, and small-volume laboratory use. The manual rotary mechanism provides reliable, controlled sectioning with full operator control, making it suitable for laboratories with lower throughput or where manual control is preferred for specific tissue types.
Q2: What standards does the microtome comply with?
A: The manual microtome follows relevant ISO, GB/T standards for histological equipment and applicable safety standards for sharp blade handling. Blades should be certified for histological use. The instrument follows applicable safety standards. Users should verify compliance with specific facility requirements for their application, including biosafety for tissue handling.
Q3: What is the warranty period for the whole machine and key components?
A: The whole manual microtome is covered by a 12-month warranty. The microtome body, mechanism, blade holder and specimen holder are covered, while blades, disposable blade holders and accessories are consumables. Damage from improper use, blade damage or unauthorized repair is excluded. Extended service contracts may be available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained histology or pathology personnel familiar with tissue sectioning, microtome use and biosafety. We provide operation manuals, training and application support. Proper specimen embedding, blade selection, section thickness setting, handwheel operation, section handling, blade safety and biosafety procedures are critical for quality sections and safe operation.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular maintenance required? What is the recommended maintenance cycle?
A: Mechanism lubrication and cleaning per manufacturer schedule. Blade holder and specimen holder alignment checked periodically. Section thickness verification recommended annually. Routine cleaning after each use. Full system maintenance per manufacturer schedule. Blade condition checked before each use.
Q7: Are supporting consumables universal?
A: Microtome blades (disposable or resharpenable), blade holders, embedding rings and forceps are available from histology suppliers, though compatibility should be verified. Long-term consumable cost depends on sectioning volume and blade type.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes section thickness range, blade type (disposable, resharpenable), specimen holder size, retraction mechanism, section counter and accessories. Additional blade holders, specimen holders and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the manual microtome and accessories with an operation manual. On-site installation and training are not included for standard manual microtomes but can be arranged for laboratory setup. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The manual microtome sections fixed, paraffin-embedded tissue samples within the specimen size, section thickness and hardness specification. Different tissue types require specific section thickness (typically 3-5 micrometers for routine histology). Very hard or calcified tissues may require special blades or decalcification. Frozen sections require a cryostat. Users should properly embed and trim the tissue block, select appropriate blade type and angle, set correct section thickness, use smooth, consistent handwheel operation, follow proper blade handling safety, maintain blade cleanliness, and handle sections carefully for mounting. The microtome should be placed on a stable, vibration-free surface. For clinical pathology, follow proper tissue processing and embedding protocols. The blade should be replaced when dull to prevent section compression or chatter. The specimen should be properly oriented in the holder. The mechanism should be cleaned and lubricated regularly to maintain smooth operation. Waste paraffin and tissue should be disposed of per laboratory procedures.
