Plus, some of their organs i. Finding anatomical similarities helps enhance a student's comprehension and tangible application. Another benefit of dissecting a larger animal is greater visibility! Larger animals have larger organs, making it easier for students see the inner workings of their anatomy. Begin your anatomical exploration of fetal pigs , squids , snakes , turtles , lampreys , dogfish sharks , rats , pigeons , rabbits , and minks!
We also provide cow eyes, sheep eyes, sheep hearts, sheep brains, sheep kidneys, sheep uteri, and sheep plucks. All of these dissection specimens provide valuable learning experiences for students and educators alike.
Whether you're a homeschool parent, a Biology teacher, or any other kind of science educator, consider how valuable, memorable, and doable animal dissection can be when mapping out your Biology lesson plans. You'll never regret opening curious eyes to a whole new world of discovery and exploration! You can use HST dissection kits for both homeschool and traditional school science labs. Our dissection kits conveniently bundle preserved specimens with the needed tools and supplies to conduct dissections in educational, eye-opening, and engaging ways.
These kits also include supporting products such as nitrile gloves , lab aprons , and dissection trays. To make it easier to find and identify an animal's arteries and veins during your dissections, HST injects some dissection specimens with different colors of dye. Our preserved specimens come in sealed, original packaging and are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.
Using the information and images inside the included dissection guides , you can easily and confidently make your way through a wide variety of animal dissections.
The resusable dissection tools inside our dissection kits may include forceps, scalpel blades and handles, scissors, curved and straight teasing needles, rulers, and medicine droppers or pipets. To reuse these dissection tools, clean them with boiling water swabs or another sterilizer.
Our products are durable, reliable, and affordable to take you from the field to the lab to the kitchen. They won't let you down, no matter what they're up against. Whether it's over eager young scientists year after year, or rigorous requirements that come once-in-a lifetime.
And if your science inquiry doesn't go as expected, you can expect our customer service team to help. Count on friendly voices at the other end of the phone and expert advice in your inbox. They're not happy until you are. HST sells standard, intermediate, and advanced dissection tools for elementary, middle, high school, and college life science labs. Check products for details.
All HST dissection tools and lab supplies come with our day satisfaction guarantee. Your dissection tools should match the goals of the dissection project. Basic instruments include dissecting scissors , forceps or tweezers , scalpels , needles straight and curved , and pipets. For more advanced dissections, where precision counts e. You can also buy one of our complete, all-inclusive dissection kits. You'll get a dissection specimen , tools, and a guide with each kit.
Dissection labs are more fun when the tools fit the hands using them. Your tools, ideally, will be functional and comfortable to handle. Comfort, as you know, is subjective. If you want fast, no-hassle cleanup, we offer disposable dissection instruments and safety gear.
If you want reusable, long-lasting dissection tools we offer those, too. They provide the best value for your lab budget. Clean your dissection tools with disinfectant soap and warm water. Don't use it around flammable materials or around appliances which might generate sparks. When I want to make a batch of micro-pipets, I clear off an area of my lab table and set out a metal tray.
I don't want to make this sound like you are walking through a chemical factory with a vial of nitroglycerine, but with the use of common sense and a bit of practice, you will soon become adept.
Place the center of the tip in the hottest part of the flame and slowly rotate the pipet. You will quickly learn to sense when the glass is soft enough to pull. Make the pull firmly, smoothly and quickly, but not too quickly, as you remove it out of the flame.
Do not pull the pieces completely apart; leave a narrow, fine tube of glass connecting the tip you are pulling on and the rest of the pipet. When this does happen and the tips seal over, set these pieces aside and use them for micro tools.
Let the glass cool for a few seconds and then bend it until the thin tube of glass snaps. This is best done over the metal tray to try to catch any minute glass fragments. Then place both the pipet and the broken tip on the tray to cool. If you have carried the procedure out properly, you will have a micro-pipet and you may discover later that the tip is too fine for a particular task, in which case, you simply use a pair of your micro-forceps to break the tip at the place you want.
I usually make about 50 micro-pipets at a time and when they are thoroughly cooled, place them in a heavy cardboard box on a shelf next to my microscope table for easy access.
You will also want to purchase a packet or two of small soft latex bulbs for the Pasteur pipets. One of my graduate students said to me a couple of years ago: "If someone had those old paper pill boxes on sale, you'd buy them. I have to admit that I am extremely susceptible to bargains, which is why I shall probably have to keep teaching long after retirement age.
In any case, this type of pipet is very useful for a one time use with strong chemicals or stains. When I use one for such a purpose, I toss it in a cheap, plastic, sealable sandwich bag before discarding it, to protect me from possible fumes and the disposal people from coming in contact with any toxic residues.
A very reasonable solution is to buy a few disposable serological pipets. These can be especially helpful when making up solutions of vital stains where dilutions of from 1 to 10, up to 1 to , are required. They are also useful if you are making up solutions of various salts as media for the culturing of aquatic micro-organisms.
These pans have a thick layer of wax in them and as you proceed with your examination of the specimen, you can use dissecting pins to position skin, muscles, etc.
At the beginning of this essay, I mentioned a starfish. If you want to buy live ones, the air freight costs are phenomenal. A starfish is an absolute bundle of mysteries and wonders and I'm going to whet your appetite by mentioning a few of them and letting you have the fun of figuring out the patterns and details.
Starfish are not, of course, fish; no more than sea cucumbers are cucumbers of any sort. Some zoologists have tried to insist that people call them sea stars, rather than starfish, but people, being stubborn, still call them starfish and probably always will.
Starfish belong to the phylum Echinodermata or "spiny skinned" creatures derived from two Greek words, one meaning "skin" and the other meaning "hedgehog," a description particularly apt for sea urchins.
To begin to understand a starfish, you have to observe it with exceptional care and patience. This is not something you can learn in an hour or a few weeks; it takes constant practice.
The genius of Darwin, in large part, resided in his exceptional ability to observe, describe, and contemplate what he had seen without imposing preconceived models of interpretation.
This is the madreporite and it, like the spines, knobs, and plates is calcareous, that is, it is composed primarily of calcium carbonate as are the skeletons of corals. This device is an intricate series of canals designed to let water in, but stop debris; in other words, it is an elaborate filter. Why does a starfish need to draw water in or expel it? With sharp pins and needles, force can be applied more precisely at the desired location without damaging the surrounding area.
They can be used for micro dissection at the finest level including the separation of cells. The material is much harder than stainless steel therefore it offers increased stability with less spring action. Insert the needles deeper into the handle to gain lateral stability or leave a longer piece out to increase flexibility.
They are suited for dissections at the microscopic scale which require increased lateral strength. Strong point needles are available with straight and angled tips. Insect Pins And Minutiens Two kinds of fine, hand made pins are available. Stainless steel pins with nylon heads are typically used in humid environments.
