How Does It Compare with Other JLab Large-Section Microtomes?
| Model | Section feed (as listed) | Specimen size and slide | Typical material |
|---|---|---|---|
| This sledge microtome (EL-ELA-5490) | 1 to 10 microns in 0.5-micron increments | Blocks up to 30 x 30 mm; 400 mm horizontal tracks | Large-area or hard specimens, soft tissue and botanical material; paraffin and celloidin |
| Sliding Microtome | 1–50 microns in 1-micron steps | Object stage opening up to 31 x 26 mm; 27 cm sliding track | Paraffin and celloidin embedded specimens; supplied in a wooden case with razor and object holders |
| Wood Microtome (Jung type) | Up to 30 microns in 1-micron steps | Specimens up to 8 x 5 cm; 42 cm slideways | Hard materials such as wood and bone |
Choose the sledge microtome when the work calls for the thinnest sections, in half-micron increments, from large or hard blocks. The sliding microtome covers thicker routine sections up to 50 microns, and the wood microtome takes wood and bone specimens up to 8 x 5 cm.
What Is the Sledge Microtome Used For?
Histopathology, botany and research laboratories increasingly need very thin sections — around 1 to 3 microns — from specimens of large area or hard material, and this heavy sledge-type instrument is built for that work. The knife clamping block travels along three horizontal 400 mm tracks, the object stage and feeding device sit on three inclined tracks, and a micrometer screw with ratchet and lever transmission raises the specimen by the set thickness for each section.
Typical uses are paraffin sections of soft animal tissues, sections of stems, roots and other botanical material, and celloidin-embedded specimens. The listing also names ear, nose and throat (ENT) department laboratories, where fairly large specimens are sectioned. With a freezing attachment incorporated, the same machine can cut frozen sections, so one instrument can serve both embedded and frozen work.
What to Specify When Ordering
- Quantity — the minimum order is 10 microtomes.
- Freezing attachment — state whether you want the microtome set up for frozen sectioning.
- Razors — the Microtome Razor is listed as a separate item and can be quoted on the same enquiry.
- Delivery details — destination country and port or city, delivery terms and any tender reference.
Frequently Asked Questions
What section thickness does the sledge microtome cut?
The feed is set by hand from 1 to 10 microns in 0.5-micron increments on a calibrated drum scale, which covers the very thin 1 to 3 micron sections the listing highlights.
How large a specimen block can it hold?
Specimen blocks up to 30 x 30 mm. Two rack-and-pinion swivelling devices orient the block, and a rack and pinion raises or lowers it for approximate height setting.
Which materials can it section?
Soft tissues and hard botanical material such as stems and roots. It gives thin paraffin sections and is also used for celloidin specimens.
Can it be used as a freezing microtome?
Yes, when a freezing attachment is incorporated. Mention this in your enquiry if you need frozen sections as well as embedded ones.
How is the knife kept steady during the cut?
The knife block runs on three 400 mm tracks and is shaped to reduce riding up or tilting, the knife holder has two screws to reduce vibration, and the clearance angle is adjusted by a screw drive.
How does the feeding mechanism work?
A micrometer screw with ratchet gear and lever transmission lifts the specimen. The feeding screw has a 40 mm effective length and an open-and-close half-nut, so it returns to its starting position when the handle is opened.
What details should an export enquiry contain?
Quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling needs, and the tender reference where one applies.
Who manufactures the sledge microtome?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it at its Ambala works in Haryana, India.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, trading as JLab, is a laboratory instrument manufacturer in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. Its sledge microtomes are built in the company’s own works rather than bought from a trader, so universities, research institutes, dealers and importers order factory-direct, each instrument is visually inspected before dispatch, and follow-up orders go back to the same manufacturer. JLab exports worldwide and ships to buyers in every region, including for example Honduras in Central America and the Caribbean, Kyrgyzstan in Central Asia, Libya in North Africa, the USA in North America and Iraq in the Middle East. Tender buyers will find the relevant information on the JLab lab tenders page.
