Kern OBL 146 Phase Contrast Microscope

The OBL 146 core phase contrast microscope is used for high-contrast imaging of transparent and unstained specimens, such as living cells. It enables the imaging of cell structures based on their different densities. Structures with higher density, such as the cell nucleus, are shown darker than structures with lower density, such as plasma.


The microscope's bright and continuously adjustable 20 W halogen illumination ensures optimal lighting conditions. In addition, the fixed pre-centred phase contrast condenser with aperture diaphragm and the light field diaphragm allow simplified Koehler illumination and thus ideal display of the specimen. Two slides can be clamped simultaneously on the stage and quickly focused by means of the coaxial coarse and fine focusing knobs.


To set the appropriate magnification, the phase contrast microscope is equipped with a revolving unit with 4 high-quality lenses with a magnification of 4x, 10x, 40x and 100x. The phase contrast microscope is suitable for use in various specialist areas, such as haematology, urology, dermatology, gynaecology, microbiology or immunology.

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.

Great durable ball
One of my dog’s favorite toy. We have had this ball for almost a year and it is still intact. My Doberman loves it and has not been able to destroy it. The size is comparable to s tenis ball. It has a little weight to it witch makes it easy to trow further.

Best toy I’ve ever gotten for my dog
The toy allows you to interact with your dog in a way that I didn’t realize was so important until I adopted a dog who was ball obsessed and a bit disconnected. We have bonded so much over this toy and it has held up so much better than 95% of the toys I’ve gotten, which have all been labeled as high-quality or durable. It is perfect for playing fetch and for tugging, as well as training. The only thing worth noting is that the rope is thin enough that it can be uncomfortable to tug with a large or strong dog. I usually wrap a leash around my hip and hook it to the rope when we are doing intense tugging (because my 75 pound dog would win otherwise). If you do go for a tug toy that has a more comfortable handle, it will not bounce and be easy for a dog to run around with in the same way. This rope makes the weight heavily in favor of the ball, so it acts more like a ball and the dog is more inclined to grab the ball. I think this toy finds right balance of ball to rope.

So good, I repurchased
This is one of my dog's fave fetch toys, and after losing it in a grassy field, I repurchased. The ball is heavy and durable, and the rope is sturdy and just the right length for flinging. When this comes out, my dog knows we're playing fetch! There's no strange smell out of the package, and while my 70lb Samoyed isn't a hard chewer, he hasn't put a dent or nick in the ball itself. It's not so hard that I'd be worried about him gnawing on it, either.
