Hi can anyone ID this diatom found in filtered seawater? Sample collected off Malibu CA. Unfortunatley the filter used did not allow for good digital images. Therefore this was taken directly from the SEM screen with phone camera. Thanks!

These are great! Was pure acetaminophen, or a tylenol capsule dissolved in the alcohol?

Not the greatest for normal microscope use, but the adjustment collar (0-2mm) ring is removable, maybe useful for a stacking rig? Small WD though, 3.82mm according to spec sheet. Outside is dirty w scratches, optics are nice and clear, collar is very stiff, easily adjustable with wrenches +soft padd...

I have a nice BHS 100W for sale, binocular, no stage clips. Can outfit with left or right hand stage. Also can include 1.25x intermediate tube and polarizers, objectives, condenser etc. I can include a trinoc head with camera adapter, but its an older BH model. PM if interested. Its taking up space,...

On a traditional microscope, what are the pros/cons of having the stage move in y axis vs the objectives/head? I have two olympus BH2s, one was modified by the lab to allow the objectives/neck/head to move while stage is immobile, similar to the old AO microscopes. My stock BH2 allows the stage to m...

Nice! all single amino acids or mixtures?

I especially like the "crackle" effect on some.

Hi is this of any help?

Yes & I'll post some photos of it shortly.

I have for sale 4 sets of BH2-KPA Simple polarization attachments (pol slider and intermediate tube) and lower polarizers. I also have two 533nm Tint plates that fit in the pol slider. Looking for some number between 200 and 300 depending on what you want.

PM or reply if interested.

These are great and I definitely see the koi swimming around. These shots particularly remind me of ceramic crystal glazes : https://ceramicartsnetwork.org/daily/ceramic-glaze-recipes/glaze-chemistry/the-new-world-of-crystalline-glazes-developing-beautiful-crystals-in-reduction/ These glazes work by...

In an effort to one up those posting polarized chemicals with long names here is a contender: a mixture of a proprietary carboxylate salt, sodium phosphate, N,N-Diethyl-p-Phenylenediamine salt, and Ethylenediaminetetraacetic Acid Disodium Salt. Taken all together it may have the highest letter count...

Great, love the crystals on the 3rd one...

I like it! is this with or without coverslip? I notice theres some dark spots on the right side, is that dust on your camera/optics or dust on the crystals? When making crystal melts or solutions I really try to filter them thru coffee filter and make sure no dust lands on the slide when crystallizi...

Awesome! Love these types of diatoms. Like small little jewlery boxes. Thanks

Here are some pics of a potassium salt evaporated from a water solution. I really like this salt because you seem to get a variety of shapes and patterns. Its fun as it tends to form these clusters of trapezoid/hexagonal shapes too. 2x, 10x, and 20x objectives and 533nm tint plate used. Last two ima...
