Precision Laboratory Bone Saw

The Precision Laboratory Bone, Cartilage and Tissue Saw is used in pathological, pharmacological, histological forensic, dental & medical laboratories for sectioning teeth and bones. It also sections a combination of hard and soft tissues.  There is no equivalent product available

After 30 successful years in producing Materials Science Laboratory equipment Materials Science (NW) Ltd, have turned their attention to the Pharmacological, Medical, Dental, Pathological and Forensic market. The result is the Precision Laboratory Bone Saw which cuts accurately through a wide variety of teeth, calcified and de-calcified bones and soft tissues but ensures that the integrity of both hard and soft tissues are preserved intact.  The bone saw is particularly useful in Pathology and Histology work.

User safety is a key design feature. Because the diamond wheel grinds instead of cuts, there is no immediate risk of injury if the wheel is touched unintentionally.

In producing a saw capable of meeting the demanding specification of this market Materials Science (NW) Ltd has been able to contain costs by an innovation that delivers water directly into the cutting zone without using a costly pumping system. The sample to be slit is placed on one of the several stages supplied with the saw and then fed into the wheel by hand control or semi-automatic gravity feed in the case of small and medium-sized samples.

Comprehensive field trials have been carried out in major pharmacology research laboratories and a hospital pathology laboratory. The resulting feedback was incorporated into the final design. Comments made by the laboratories include:

"Bone fragmentation and damage to soft tissues was minimal."
" does not ‘wrench’ out much of the desired bone marrow muscle of the underlying tissues as do other saws."
"cartilage surfaces were fine as expected at the uppermost levels, bone fragmentation was minimal, marrow cell loss was reduced. At lower levels, >100 microns, marrow cells were left mostly intact and cruciate ligament was better preserved."

Available in 110v A.C. or 220v A.C versions.

Given this exceptional performance, the low cost of the equipment makes it an attractive proposition for any pharmacological, medical, dental, pathology, histology or forensic laboratory.

In summary, the advantages and features of this new saw are:

  • It is low-cost, and produces high-quality results.
  • Water is delivered directly into the cutting zone eliminating "burning".
  • Most of the abrased material is vented during slitting - little or no debris is compounded into joint spaces.
  • Control of the wheel rotation is by foot and/or press-switch
  • The transparent splash guard allows the operator to observe the sample during sectioning.
  • The thickness of the section is controlled by means of an adjustable end stop.
  • The main switch is key controlled.
  • Calcified bones embedded in resin can be sectioned easily.
  • An "all over" transparent cover protects the saw when it is not in use.

Examples of sectioning using the Precision Laboratory Bone saw are shown by clicking here.

The slitting wheel is 12.3 cm in diameter and 0.5 mm thick.  Two versions are available: one with a continuous rim of diamond particles, the other with a semi-continuous rim.  The former is more suitable for plain bones, the latter for bone combined with tissue.  Both are low cost to replace, unlike band-saw blades.  Blades for sectioning bones and teeth with metal implants/fillings are available.

A wide variety of samples can be sectioned from as small as a rat’s tooth to a human femur and the full diameter of the ball joint.  Even larger samples such as a dog’s head can be sectioned by turning the sample whilst cutting.

Sections can be precisely made to within one mm.

A Hands Free Cutting System is supplied with the Saw for sectioning small and medium-sized samples.

Both versions can be supplied to operate from either a 240v or 110v ac mains supply.

An important feature of the Precision Laboratory bone saw, resulting from feedback obtained during trials, is that it can be fully disassembled, to allow thorough cleaning. This is considered a highly desirable feature in medical and dental laboratories.
