(Sodium Nitrate & Zinc Sulphate)

Livestock & Companion AnimalsParasitology

Examination of faeces from livestock and companion animals for parasite eggs and oocysts is an important diagnostic procedure in most veterinary practices and laboratories. One of the most common techniques uses the concept of floating parasite eggs to the surface of a special solution in order to be detected under the microscope.

Specific Gravity

Basically, this is achieved by increasing the density or specific gravity (S.G.) by dissolving certain salts in water. The S.G. has to be optimised in order to allow parasite eggs to float and faecal debris to sink. It is generally recognised that the S.G. of faecal flotation solutions should be within the range of 1.18 to 1.27 to detect most (but not all) ova.

Vetlab Supplies Ready-made Fecal Float Solution

We offer ready-made faecal flotation solution of either Sodium Nitrate or Zinc Sulphate both of S.G. of 1.200. These solutions are the most popular and recommended for general use. We offer both solutions to accommodate personal choice, although we find that our Sodium Nitrate Solution has less shrinkage effect on Giardia Cysts. However, we can make solutions of different S.G. values to personal order. These solutions are ideal for use with our ‘OvaTube‘ and McMaster slides.

Advantages of Ready-Made Faecal Flotation Solutions

Some Veterinary Laboratories make their own flotation solution but this can be expensive, messy, and time-consuming and the S.G. must be adjusted accurately to achieve the best results.

Our ready-made solution offers

  • Less Cost
  • No hassle or mess
  • Saves time
  • Accurately measured S.G (standard 1.200 or to your requirements) Available in 1 and 5 Litre volumes


StatSpin OvaTube

Improved Accuracy without the Mess!

OvaTube is the perfect in-clinic solution for fast, easy, and accurate testing on small animals such as cats and dogs. The StatSpin OvaTube is a unique device allowing you to perform faecal parasite testing using the more accurate ‘gold standard ‘centrifugal’ flotation method. With a built-in sampling tool, the StatSpin OvaTube offers a fast clean, easy and above all, superior method of detecting ova all in one unit.

McMaster Slides

McMaster Worm Egg Counting Slides

McMaster worm egg counting slides are widely used for performing faecal worm egg counts in large animals such as horses, cattle and sheep in order to estimate intestinal parasite burdens and check worming efficacy.

Vetlab McMaster 2 Cell Counting Slide

Our McMaster Slides have some significant advantages compared to the conventional glass type.

  1. Made from the strongest optical acrylic available — which is more robust than glass.
  2. The upper section is fused to the lower section by sonic welding rather than glue. This makes the slide more durable and avoids faecal residue being trapped between the pieces.
  3. The upper section grids are printed in blue ink which lasts for some years with correct care. This allows the grid lines to be focused on more easily and worm eggs to be seen underneath the grid lines.
  4. The grids consist of 6 columns (instead of 9), the width of each column fitting exactly the field of view at x100 magnification, allowing counts to be performed faster.
  5. Our Vetlab McMaster slides are one-third of the cost of a conventional glass slide!
