Centrifuges

Most centrifuges are very simple to program. On many models, these can be stored for quick access in future runs to prevent having to continually input your centrifugation parameters.

Swing-out rotors are generally used for speeds up to 5,000rpm with pellets formed in the bottom of the tube. Fixed angle rotors generally come into their own for speeds up to 30,000rpm / 65,000g or higher with pellets being formed towards the side of the tube. 

Like any piece of heavily used equipment, the more often it is used the more regularly you need it serviced. We generally recommend a once yearly Preventative Maintenance service check.

This is normally caused by an incorrect balancing of rotors and/or buckets, for example by only placing tubes in one bucket in a 4-bucket swing-out rotor or by placing only 1 tube in a fixed angle rotor. An imbalance can cause major damage to a centrifuge although the imbalance sensor will normally stop the centrifuge to avoid further damage to the centrifuge. To prevent imbalance issues always balance opposite positions in both buckets and fixed angle rotors you blank tubes filled with water if necessary.

Relative Centrifugal Force (RCF) is the “g” force applied to the sample. This figure is comparable across all centrifuges. RPM relates only to the speed of the rotor and is only one factor used to calculate the g-force, this means setting the same RPM in 2 different centrifuges may generate very different g-forces (RCF).

Refrigeration helps maintain a constant temperature within the centrifuge, non-refrigerated centrifuges will generate frictional heat during the run cycle. Therefore, if your samples are heat labile samples a refrigerated centrifuge should be used. In many cases, scientists like to select below ambient temperatures such as +4oC .

Speeds can be programmed from 100rpm up to 22,000rpm

There are now several models available which allow controlled heating and refrigeration within the range +4 to 60 oC. Temperature is accurately controlled through the programmer.

Rotors and buckets are generally manufactured from high quality anodised aluminium. It is always advisable to use non corrosive cleaners. Prolonged use of acid or alkaline cleaning fluids can lead to corrosion. Ideally neutral pH cleaners and alcohols are best.

The life of a rotor and buckets is very much down to use. This varies widely depending on the model, frequency of use and speed of use. It is always recommended to have them checked during your annual maintenance check. Some centrifuges calculate the number of cycles a rotor has performed and will inform the user to replace it or have the rotors inspected.

No. It is very important to always use accessories manufactured for the centrifuge you are using. Using other manufacturer’s accessories is dangerous and may lead to serious damage to the centrifuge. Most centrifuges now have rotor recognition sensors ensuring only the correct accessories are able to be used.

This is normally a clear indication that samples are not being balanced properly in the centrifuge. It may also indicate another maintenance/service issue. Check the balance of your samples, if the problem persists stop using the centrifuge immediately and contact a service engineer.

If you use hermetic or biohazard sealing caps/lids all leakage and breakage should be contained. The buckets, lids and adapters can then be autoclaved or decontaminated as necessary.

Some centrifuges provide security settings to provide unauthorized use of programs or settings.

FAQ

Microscopes

The upright microscope is perhaps the most commonly used and features that the objective is facing downwards. 
Where and when an upright microscope is used?
The upright microscope, in the case of “biological” samples, is used for samples placed on a classic slide. 
The sample is then placed on a slide, treated in the best way for the observation method to which it must be subjected and then covered with a coverslip with a thickness not exceeding 0.17 mm.
Due to its construction, the upright microscope can only work with slides. 
It is not possible to work with other coverslip thicknesses: the image would not be in focus or not sufficiently clear. 
Inverted microscope, instead, has an opposite construction to the upright microscope.
In this case the objective is facing upwards and the sample with the surface to be examined is placed on the microscope stage. 
Where and when an inverted microscope is used?
The inverted microscope is mainly used in laboratories where cell cultures are treated. 
In these laboratories plastic vessels are used (Petri, Terasaki, flasks or other containers) with bottom thicknesses greater than 0.17 mm. 
Sometimes slides are also observed but in this case the specimen placement has to be opposite with respect to the upright: the glass slide thickness (1.2 mm) must be facing the objective.

Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing “large” objects that are visible to the naked eye at low magnifications (under 50x). A stereo microscope provides an upright and unreversed, 3-dimensional image of the specimen. 
A compound microscope, also known as high power or biological microscopes is used to view micro specimens that are not visible to the naked eye at high magnifications (40x-1000x). A compound microscope provides an inverted 2-dimensional (flat) image of the specimen.

There are two ways to take a photograph through a microscope. 
First, you can attach a microscope camera to either an ocular or trinocular port. 
Video cameras, as long as they are the common “C-mount” type, can be used with every Optika Microscope models.

Second, you can attach a SLR camera with an universal adapter and “T-Mount” matched to your camera brand and model.

This number identifies a finite tube length objective. 160 millimeters is the distance from the opening of the nosepiece (where the objective is screwed in) to the top of the observation tube (where the eyepiece is inserted). If this distance is lengthened, e.g. by insertion of accessories in the light path above the nosepiece, spherical aberration will result, unless optically corrected lenses are included in the accessory.

This inscription identifies the objective as an infinity-corrected objective. Light rays emerging from such an objective are in parallel bundles projected toward infinity. Such an objective, with its many advantages, requires a tube lens in the light path to converge the parallel rays so that they come to focus at the plane of the eyepiece diaphragm.

With standard colors for most manufacturers, these rings make it easy to identify the magnification of the objective:
A red ring means 4X or 5X.
A yellow ring means 10X
A green ring means 20X.
A blue ring means 40X, 50X or 60X.
A white ring means 100X.

Yes but although you may be able to screw the objective into the nosepiece, the presence of a tube lens in the light path will result in a deteriorated image.

No, because the finite system does not include a tube lens to bring the parallel rays to focus.

Yes, provided that the objective has a RMS thread.
This combination is usable, although that would not be advisable for some reasons:
1) The focal length of some producers’ tube lens (180mm) is not the same as that of other manufacturers. As a result, the magnification of the objective would not be precise. 
2) Aberrations would be introduced because other companies correct for lateral chromatic aberration in the tube lens.
3) The objective probably would not be parfocal with Optika objectives.

The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.
