Immersion oil is used to increase the numerical aperture of the objective lens. Immersion oil allows you to observe microscope samples with higher resolution and magnification power. By using oil immersion technique, you significantly reduce light loss in the lens.
Initially, immersion oil was manufactured using cedar tree oil, but this oil tends to get thicker with time and lose its properties. Immersion oils used nowadays are synthetic and meet all quality standards. Thus, the immersion oil must be transparent and free of impurities that can cause clouding of the lens and image distortion. It also must have a refractive index equal to that of the lens and the slide.
We offer high-quality immersion oil that meets all the necessary standards and is safe for the objective lens. Levenhuk immersion oil can be easily removed from the lens. It is suitable for all microscope types except for fluorescent microscopes. After you finish your observations, the oil must be wiped off the lens with a soft cloth. You should also clean the slides with a cloth soaked in a cleaning solvent. The immersion oil forms a film on the lens, which should be occasionally removed with a solvent.
Storage Instructions: keep in a tightly closed container at room temperature below 30°C (86°F) away from direct sunlight.
Nominal volume: 5 ml.

Hi, what is refractive index of this immersion @ 976nm ? Levenhuk Customer Service:
Hello Pavel, thank you for interest in Levenhuk products. Currently we do not have such a specification. We will double check it with our product manager.
Can I use the oil with levenhuk 50l plus? Should I put it on a coverslip or where? Levenhuk Customer Service:
Levenhuk Rainbow 50L PLUS Microscope doesn’t have an immersion lens in the kit, so you won’t need it for work. A drop of immersion oil should be placed on the top of your cover slip.
Hello! I have two questions: 1. Oil gets thick after a few hours of use. My work involves long hours of observations, and after that it becomes much harder to remove oil from objectives and slides. Is it normal? 2. What can I use to clean it off? Special solvent or alcohol? Levenhuk Customer Service:
1. Yes, it does happen. 2. We recommend using special optical cleaning solutions and tools as they keep optical coatings safe. Check out this section: https://www.levenhuk.com/catalogue/accessories/optics-cleaning/.
What's the purpose of immersion oil? It magnifies images even more somehow? Levenhuk Customer Service:
Immersion oil doesn't magnify images. Only microscope eyepieces and objectives are capable to do that. Immersion oil is used together with powerful lenses to capture more light and make produced views more sharp.
is it synthetic? Levenhuk Customer Service:
Yes, Levenhuk immersion oil is synthetic.
