Thanks for the demonstation. I've just bought one of these and look forward to your future videos on using a centrifuge. The DNA usage mentioned in that incomprehensible instruction leaflet sounds interesting. Also, if you manage to buy some glass or clear plastic tubes for the centrifuge then please let us know the correct size and where you sourced them. Thank you again for a great video!
Plastic polypropylene tubes similar (but not identical) to the ones supplied are available on eBay. They hold 20 mL and are about 110 mm long and 21mm wide with a lip on the tube to hold it in place and a plastic cap. I've bought and tried them and they're fine. Because they're slighly longer than the supplied ones then you'll probalby need to replace them all inside the centrifuge and not try to mix and match the supplied tubes with the bought ones.
I've bought the same centrifuge a few months ago. works fine, a bit noisy. I put clear 15 ml plastic centrifuge tubes into the 20 ml tubes. Also doing some honey samples to determine pollen; good video as always.
I'm really enjoying the different things you are finding to investigate under the microscope. I couldn't tell from the video, but do you think all the motion you could see there was Brownian movement or did there seem like there was some actual motility there, too?
Awesome video as always. Thank you. I am thinking of getting a centrifuge for my classroom to separate soil samples into sand, silt and clay. We can do this without a centrifuge but it can take days for the clay and silt to settle out of suspension. This centrifuge looks like it may be an option but it looks and sounds a bit scary! lol. Is there a way to mount it to a table?
It has suction cups. Maybe possible to also screw it to a wooden board. Manual centrifuges do exist, they also spin fast, but I think that they might be a bit dangerous. Here I use a manual centrifuge: ruclips.net/video/GLAGCb5wONQ/видео.html
Did you use tap water, bottles water OR a filtered water which had the ions cat ions and organic matter removed to the ppm? for example a RO filtered water? My question is because I wanted to know if the other particles shown in the slide were from the honey or where already present in the water? thank you.
I used tap water. If the other particles were part of the water, then the water would really be unclean (at this concentration). It is possible (and even likely) that there are impurities in (tap) water, but not at that high of a concentration.
Are those smaller bits moving because of Brownian motion or are those moving bits Bacteria ? My understanding is that Honey has Anti bacterial properties therefore should be void of live cultures. Hmmm... Interesting.
I have exactly the same model that i bought on ebay for the same purpose and make my pollen catalog ; it works perfect :)
Hi Oliver, I have been looking at buying one of these for some while so really grateful for the video especially the dismantle part! Thank you.

How's the fit with the 15ml tubes?
I would greatly appreciate it if you make an informative video about staining live samples or coloring them.

Very interesting video. Thanks for teaching other people.

Would micro animals such as nematodes and tardigrades survive centrifuging?
I just both one exactly like it weeks ago. Haven’t used it yet. I notice this video is two years old. How has that one held up?
Sir can u make video on stains

Call the company, tell them for a grand in merchandise you'll rewrite their introduction paragraph into readable English :-)
well you can always use a paperfuge.
Wow. Honey is full of microbes, should I stop consuming honey....😅
