4 McMaster Method Microscope Slides, by FEC Source $17 ea, Fecal/Worm Egg Count for Parasites for Veterinary Use. Livestock Parasite Management. Check Dewormer Efficacy -FECRT Reference Guide Included

Haven't, tried yet, waiting for microscope, look excellent quality, well packaged, WONDERFUL THANKYOU.,edited , @amazon, in hindsight i can fully understand that you would have to have a policy of shrinking pics.@ newbies like myself , Low res pics dont show the info provided by FECsource. This info is major important to newbies at doing fecs, eg drug type and when to post test., 3 major drug types mentioned , pyantel, 7 days , benzimidazoles 10 days , ectins 14 days.Re FECRT calculation. (FECRT means fecal egg count reduction test)FECsource have provided a very very simple (when reading think 4 year old human child basic mathmatics eg one plus one equals two that is “addition “” “” subtraction”” is five take away three equals two,)calculation for u to work out the pretreatment epg compared to the post treatment epg, so u can work out drug resistance in that particalur animal, a reduction of less than 90-95% indicates a resistance to that drug ,all this info and more is available on their website.Part 2Low res pics dont show the beauitifull rounded corners in the inside of these slides, it took me over two hours to get that picture , shadeing problems , reflection problems , light problems etc.Part 3 again difficult to see because of low res pics , on the slide itself underneath the grid is written “” the words FECsource.com macmaster slides , i tried to scratch off that “m” at the start of the word macmaster from both underneath and from the top of the slide , I COULD not scratch it off .i also wrapped the same slide in cling wrap 3 layers , and measured the the grid with calipers , it is 1 cm by 1 cm .

good macMaster cmara and fast seller

Works great as described!

Decent slides, but definitely not the best.They are acrylic, not glass, which is nice so they dont break.The top slide is not securely glued to the bottom slide so fecal matter gets stuck between the 2 and is difficult to clean.They do the job but I expected something a little nicer for nearly $17 a piece!

They work as they're supposed to.

They work! But the quality is very poor. I bought 4 slides. I have use themVery little they come apart after 2 or uses.I would not recommend buy this brand.

4 individually packaged slides along with basic directions for use. Should work perfectly for doing parasite egg counts for my goats.
