Hand Microtome External Milled Knob Manufacturer,Supplier and Exporter in India
Product Code : EL-BE-4452
Jlab Export is a leading Hand Microtome External Milled Knob Manufacturer,and suppliers in India
Hand Microtome External Milled Knob (code EL-BE-4452) is a hand-held microtome for cutting thin sections of plant and soft tissue specimens in biology and botany teaching labs. An external milled knob advances the specimen against a micrometer scale of 50 divisions of 10 microns, giving cuts down to 10 microns on samples up to 20 mm across, and it comes complete in a case. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Microtomes?
| Model | Section control listed | Mounting and supply |
|---|---|---|
| This microtome (EL-BE-4452) | Micrometer scale, 50 divisions of 10 microns; minimum cut 10 microns; samples up to 20 mm | Hand-held, external milled knob; complete in case |
| Hand and Table Microtome | Least count 0.01 mm; 20 mm vertical lift | 80 mm diameter stage; fixing clamp for the bench edge |
| Hand Microtome | Sections in steps of 10 microns | Portable; plano-concave razor and table clamping device in a storing box |
| Rotary Microtome | Ratchet feed advanced by the drive wheel; safety device disengages the feed | Heavy base with hinged cover |
Pick this model when students should read the section thickness directly off a graduated scale and the microtome needs a case for storage between practicals. The hand and table model suits groups that prefer to clamp the instrument to the bench, and the rotary microtome is for heavier, mechanically fed sectioning.
What Is the Hand Microtome Used For?
Thin, even sections are what make plant tissues readable under a compound microscope, and a hand microtome produces them far more consistently than a razor held freehand. The specimen — a short piece of stem or root, usually supported in pith or a slice of carrot — is loaded into the microtome, a turn of the milled knob raises it by a measured amount, and a sharp razor slides across the top to take off one section. Because each division of the scale stands for 10 microns, students can see how far they have advanced the sample and repeat the same thickness. It is widely used for transverse sections of dicot and monocot stems and roots in class 11 botany practicals and in college plant anatomy courses, as part of the section-cutting kit on a botany lab bench.
Keep the razor wet while cutting, collect the sections in water, and pick the thinnest for staining and mounting. Clean and dry the microtome after each session and return it to its case so that the threads and scale stay free of sap and dust.
What to Specify When Ordering
- Number of microtomes — the minimum order is 10 units; many labs allow one per two or three students.
- Razors and accessories — list any microtome razors you need; they are quoted as separate items.
- Alternative models — say if you are also considering the clamp-mounted hand and table microtome or the rotary microtome.
Frequently Asked Questions
What is the thinnest section it can cut?
The minimum cut is 10 microns. In practice the thinnest usable section also depends on the specimen and on how sharp the razor is.
How is section thickness set?
With the external milled knob, read against a micrometer scale of 50 divisions, each worth 10 microns.
How large a sample can it take?
The maximum sample section is 20 mm, which covers the stems and roots normally sectioned in teaching labs.
Does it come with a case?
Yes, it is supplied complete in a case. A razor is not listed as included, so add microtome razors to your enquiry if you need them.
What should an export enquiry include?
Quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling needs and any tender reference.
Who manufactures the Hand Microtome External Milled Knob?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its Ambala works and supplies it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of biology lab equipment and scientific instruments in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. This hand microtome is made in JLab’s own works and not sourced from a trader, so schools, colleges, dealers and importers order it factory-direct; each one is visually inspected before it is packed, and repeat orders and spares come from the manufacturer itself. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to every region — for instance the USA in North America, Thailand in Southeast Asia, Mauritius in East Africa, Morocco in North Africa and Samoa in Oceania. See the JLab lab tenders page for tender supply.
