Laboratory microscopes: Brand manufacturers and top quality

What are microscopes needed for in the laboratory?

The possible areas of application are as varied as the individual types of microscope. Highly specialized laboratories in particular often have devices that have been designed and assembled for this purpose. The benefits are always similar - the laboratory microscope produces a high magnification of an object or sample, in that the resolution exceeds that of the human eye. This makes even the smallest components, structures and particles visible, down to a maximum of 0.2 micrometers (Abbe limit).

The most common areas of application and use of microscopes range from laboratories in medicine, pharmacy, biology, technology and production to institutions such as schools, universities and research departments in the public and private sectors. The right microscope for the laboratory depends primarily on the required magnification and special equipment features. These include the following aspects:

• Number and lens curvature of the individual objectives

• Phase contrast

• Size and distance setting between eyepiece and nosepiece

• Additional illumination

• Object micrometer

• Color filters

• Dark field condensers

Microscopes for laboratories and research - our range at a glance

Not all microscopes are the same - if you want to buy laboratory microscopes, you should first take a close look at the individual options and features. Do you need clinical microscopes, upright microscopes or digital microscopes? At MedSolut, we therefore offer you individual advice as well as a wide range of different microscope types for training, medical professionals and specialist companies. This includes the following categories in particular:

Binocular microscope

As binocular microscope are devices that are equipped with multiple lenses instead of a single eyepiece and provide superior optics. This allows the image to be viewed with both eyes, which helps to protect the eyes, especially during prolonged use. In our range at MedSolut you will find binocular microscopes with advanced features from the manufacturers KERN Sohn, SHIMADZU, hund and A.KRÜSS for eye-friendly working.

Monocular microscope

With a monocular microscope is the classic design of laboratory microscopes, which is suitable for simple applications in schools and companies for examining microorganisms. These models have a simple design and can be purchased inexpensively. They have integrated lighting, an angled view and a rotatable object head; the image is displayed via a single objective. At MedSolut, you can choose from various variants in this category, including, for example, the KERN transmitted light microscope OBE-1 and the Levenhuk 50L NG.

Stereo microscope

To the stereomicroscope category includes representatives that enable a three-dimensional view through two objectives. This is achieved by different orientations of the objectives on the test material in combination with two eyepieces. This makes them the best companion for inspection and fine machining in the field of electronics. Some stereo microscopes have an additional zoom, which makes work even easier and more precise. You can find these lab microscopes at MedSolut from manufacturers such as KERN, hund, Levenhuk and A.KRÜSS.

Trinocular microscope

Fourth in the group is the professional trinocular microscope which has four objects and two eyepieces. It enables parallel observation via an additional tube so that two people can work on it at the same time. A camera can also be connected so that the digital microscope image can be transferred to a screen. Examples from our range include the SHIMADZU CX41 microscope and the Levenhuk 870T can be mentioned.

Laboratory microscope: design and operation

So that you can make full use of the microscope's comprehensive functions, it is worth taking a look at the most important components and the correct procedure for setting up such a device. The individual components may differ depending on the model and design, but the basic operation is similar in most cases.

The most important components of a microscope

Light microscopes consist of two (or more) lens systems, which are built into the eyepiece and the objective. The object to be observed is placed on the microscope slide, where it is illuminated by a light source - this beam is magnified by the lenses in the object. In detail, the structure of a standard laboratory microscope is as follows:

• Eyepiece: The eyepiece is the part at the top of the laboratory microscope through which you look when using it. It contains lenses for magnifying the specimen.

• Tube: The elongated tube between the eyepiece and the belly of the device is the tube. This provides a distance magnification so that the focal length can be individually adjusted.

• Revolving nosepiece: The revolving nosepiece also contains lenses, which in turn are divided into different objectives. These lenses are refracted to different degrees, so that various magnifications can be covered with one microscope.

• Stage: The specimen can be fixed on the stage so that it lies flat and can be optimally illuminated. Laboratory microscopes have special specimen holders or clamps for this purpose.

• Light source: The light source, e.g. LED lighting, illuminates the specimen and makes individual structures both visible and differentiable. Depending on the type of microscope, illumination is from below, from above or from the side.

• Coarse and fine drive: The coarse and fine drives are used to focus the image by changing the distance between the objective and the specimen at the smallest level.

• Stand and base: These two components are used to set up the microscope. The base provides a stable transition to the table, the stand accommodates all the important components of the device.

Important safety information

Always use the laboratory biological microscopes on a flat surface and ensure that the device is stable. Also, only lift the microscope with both hands and be careful not to touch the light source or the lenses on the object directly with your fingers - this could cause damage.

Notes on using laboratory microscopes

For ideal microscopy results, it is important to observe a few precautions and rules when using the microscope. These not only make handling easier, but also prevent damage to samples and the device:

• Place the slide in the center of the object to be examined and clamp it with the clamp when microscoping This prevents the sample from slipping or even falling off.

• First set the revolving nosepiece to the lowest magnification and then work your way down. This will give you a good overview.

• When operating the rotary knob near the object, make sure that the objective and carrier do not touch each other - otherwise both parts may be permanently damaged.

• Slowly increase the distance between the object and lens for a sharp image by turning the drive wheel. By using immersion oil, even high magnifications can be brought into focus.

• Adjust the brightness with the diaphragm and the mirror.
