Formes flottantes à conformation rayonnante. Différentes espèces d'amibes, séparées de leur support peuvent adopter une conformation étoilée en développant des pseudopodes tout autour de leur cellule. Cette forme flottante est transitoire, la cellule adopte sa forme rampante si elle reprend contact avec un support.
This picture shows an example of some of the practical laboratory facilities available to students in our Science Building.
Exploded view. The left is the camera to T Mount adapter, then a femail T thread to Female T thread spacer tube, and finally the mount to the microscope which includes a 2.5x / 90 lens.
We have our suspicions about this 2.5x lens. Gene thinks it may be giving us worse resolution than we should really have. And it looks like it needs to be carefully adjusted in order to make the microscope behave 'parafocally' (where the eyepiece focus and the camera focus are in sync.)

Just picked this up at Fry's for $69. Outstanding value, and simple as pie to hook up to the computer.
Anabaena est un genre de cyanobactéries filamenteuses (anciennement appelées algues bleues). Elle sont connues pour leur capacité à fixer l'azote.

My blood; viewed at 100x through an Olympus BH2 microscope fitted to my Canon 5DMKii. Higher magnifications to follow soon.
Dr. Mark Groszos, associate professor, oversees the eight advanced polarizing student microscopes and one research/teaching model with full digital imaging capabilities. Groszos said the department is using the microscopes in an upper-level undergraduate class that delves into the study of rocks and minerals. Several geosciences students plan to use the microscopes in their senior projects, and faculty members are incorporating the equipment into their research programs.

Let's start of with the user-friendly features! Not all scientists are equally tall, nor are their eyes equally far apart. That's why the oculars (eye pieces) can be tilted up and down, and can they slide apart. Through both oculars shines a light!
BF100 laboratory fluorescence microscope, designed for biomedicine cell detection, immunofluorescence analysis, cell culture observation, fluorescence in-situ hybridization (fish).
New generation of infinity color corrected optical systems and professional plan semi-apochromatic fluorescence objectives, present you sharp and bright fluorescence image.
Professional fluorescence filter system, imported optical material and broadband multilayer coating, high transmissivity, mould proof, heat insulation and safety protection system, OSRAM brand mercury lamp, digital power-supply control.
Swallow tail slide switch easy to change filter cubes, three paths for fluorescence and one for bright field, four filter cubes can be mounted. OMEGA brand professional fluorescence filter cubes achieve excellent performance
Scientific research class cold CCD, high resolution, fast transmission. Intelligence Chinese fluorescence image processing software, meets any request of the most professional picture processing.
6V/30W transmission illuminator, Kohler illumination and swing out condenser enable to get full brightness at any magnifications under bright field observation. Various observations can be achievable by using dark-filed, phase contrast, polarization accessories.
The first routine and educational microscope to incorporate renowned Infinity plan optical system.
The BM500 is a built-to-last, top-of-the-range biological microscope ideal for basic laboratory use or educational purposes. Of course, the BM500 maintains the same operational ease and rigidity common to all other microscopes. And also the digital camera can be attached when the trinocular eyepiece tube is mounted.
For her special project, an excellent guest student from Ireland wanted to identify bacteria that degrade estrogen. Since it is a regulated substance, she chose estradiol instead, as it is an estrogen precursor. Another student chose androstenedione instead of testosterone for much the same reasons. Tongue in cheek: they proposed to have the bacteria do battle each other at the end of the project...
