KIRSCH Laboratory Refrigerator LABEX® 520/720
The KIRSCH LABEX® 520/720 Laboratory Refrigerator with explosion-proof interior (zone 2) complies with DIN 13277 and is equipped with an innovative PRO-ACTIVE control system that enables permanent monitoring of the performance data. Two standard PT-1000 sensors ensure precise temperature regulation, while the efficient convection cooling ensures even temperature regulation and only slight temperature differences between the individual storage spaces. The 70 mm thick insulation reduces the energy consumption of the laboratory refrigerator.
In the event of a power failure or other malfunctions, a visual and audible alarm indicates the malfunctions of the cooling system. The data of the integrated min. and max. temperature memory can be read via USB interface or via a network, depending on the version. The electronic temperature control is tamper-proof.
The Kirsch laboratory refrigerator is available in various sizes and with different equipment.

Our dogs wouldn’t touch this chew toy
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
I ordered this Bacon Flavored Nylon Chew Toy for my boxer mix dog.
She sniffed it and wouldn’t have anything to do with it. We waited a day and still no luck. We figured that we would give it to our pit bull because she can annihilate a chew toy. Nope, she wouldn’t touch it.
The thing looks like a big chunk of plastic with a very faint smell of bacon.
Based on our experience with this product I cannot recommend it.

Surprisingly Tough Chew Toy for Aggressive Chewers
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
This chew toy is made from a very hard nylon style material and feels substantially tougher than the average dog toy. It definitely seems geared toward aggressive chewers and larger dogs that destroy softer toys quickly. Our pup immediately liked it, especially with the peanut butter groove feature, which helped keep them interested longer.
The toy feels almost indestructible during normal chewing sessions and has held up very well so far with no major gouges, cracks, or chunks coming off. Based on first impressions, I would expect this to last at least a month or more for many dogs, which is far better than a lot of chew toys in this price range. Another nice bonus is that it is dishwasher safe, making cleanup easy after using peanut butter or other treats in the groove.
As for the teeth cleaning claim, I honestly cannot comment much on that yet. I have not personally noticed any obvious difference in our dog’s teeth or dental condition from using it. Still, as a durable boredom relief chew toy for aggressive chewers, it has been a solid performer so far and seems like a good value.

My dog approves
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
My dog absolutely loves these flavored chew bones! She’s a very aggressive chewer, and this toy has held up really well to her constant chewing. It keeps her entertained for a long time and seems to be one of her favorite toys.
I also love the unique scorpion shape. Living in the desert, we see scorpions pretty often, so I thought it was a funny and fitting design. While I don’t expect it to turn her into a scorpion hunter, it definitely adds a fun touch!
The flavor keeps her interested, and the durable material makes it a great option for heavy chewers. Overall, a great toy that has been a huge hit with my pup. Will definitely be purchasing more!

Cheaper than shoes!
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
Instant hit with a dog that likes chewing shoes! This is a much cheaper alternative than a new pair of shoes. They state it is indestructible but at the same time the directions state when it reaches a certain chewed up point to take it away. So obviously this is destructible but it does allow for a lot of chewing. I can not personally attest to the flavor but it must be good because the dog wanted this chew before i even unwrapped it. It is somewhat ugly in both color and shape but I have had no complaints from the dog! I also appreciate that this can be put in the dishwasher to clean. To be honest i have never considered that with other toys and I do appreciate that it can be placed in the dishwasher. Most importantly, this lasts, the dog is in love with this, there are multiple limbs for the dog to chew. It’s his new favorite toy and worth every bit of the cost!

Durable
Size: Medium & Large, Color: Red Scorpion
This bone has proved to be durable and tasty (per our Labrador). She chews and chews with barely a dent. I’m guessing the flavor is good because it’s still her go-to bone after almost a week. Beware of your pet dropping it on your toes though as it is quite hard.
