Description of this part for the microscope.

microscope consists of the following elements:
- the holder into which the condenser is inserted (the so-called condenser basket)
- the clamp located inside this holder, with an internal diameter of 37 mm
- the condenser mounting / clamping screw
- and the mechanism that moves the condenser, consisting of a control knob, a shaft with a pinion, and a rack

Here I am presenting the first three elements, i.e. without the control knob, without the shaft with pinion, and without the rack.

The N-117M / DN-117M microscope is a fairly good laboratory microscope manufactured at the Chinese NYO factory and sold worldwide under various names. These microscopes are known and sold, among others, as:
- Delta Optical Genetic Pro (mainly in Poland)
- AmScope B340 / T340 (mainly in the USA and the rest of the world through Amazon)
- Labtron LEM-C10 / C11 / C12 (mainly in the UK)
- Sigeta MB-207 (mainly in Ukraine)
- Boeco Germany BM-117 (mainly in Germany)
- BestScope BS-2020 (mainly in the USA, shipped worldwide)
- Brunel N117M (mainly in the UK)
- Apex N-117M (mainly in the UK)
- Surgifield SM-DN-117M (mainly in Nigeria and West Africa)
- Eurotech DN-117M (mainly in Peru)
- Biocare DN-117M (mainly in Peru)
- Viresa N-117M (mainly in Mexico)
- Eurolab DN-117M
- Nexcope N-117M
- Novel N-117M

This is certainly not a complete list of names – many sellers give the microscopes they sell their own names without a model number (just like Delta Optical in Poland). The best way to check whether this microscope part fits your microscope is to compare the appearance of your microscope with the microscope from which this condenser holder was removed (https://www.microscopeparts.eu/microscope/optical-n-117m-388).

The N-117M model has a binocular or trinocular head, while the DN-117M model has a built-in digital USB camera (hence the “D” at the beginning of the name, for “Digital”) – but the stand is shared by both models, so this condenser holder fits both models.

When might this microscope part need to be replaced?
- if the microscope has a condenser holder in which the clamping screw is missing, bent, or broken off with a fragment remaining in the thread. This is a common fault
- if the clamp is missing from the inside of the condenser holder – this is a common problem because the clamp can be pulled out
- if the metal ring of the condenser holder has been bent as a result of an impact; in this case, the condenser simply cannot be inserted into the holder

The last photo in the gallery shows the stand of an N-117M type microscope, with an arrow indicating which microscope part is being described and where it is located. This helps prevent any confusion when identifying the microscope part.
