Specimen Holder

Post by houstontx »

Where to buy or how to make a DIY specimen holder? I am currently using a piece of stiff wire which works but is a pain to get into place easily.

Thanks,

I have many different sized needles for varying insect size. I just dip the needle tip in super glue and stick it in the specimen. The needle can be stuck into clay and maneuvered easily.

I have a 'Microscope stage' from Bioquip - really its a nifty little specimen holder that allows you to rotate and reposition the specimen easily.

These look pretty cool. I used a much more basic model when i began.

I modified a similar solder station. The great thing about this one is I can alter the length of the arms :)

Specimen holder

I use pipe cleaners with a pin glued on the end and then glue the pin to the insect. Far cheaper than a goniometer and just as effective. Microscopists/macroscopists are known for their patience, so this is just another day at the office.

Welcome MAvis !

You can post up to 1024 square, with a 300kB size limit, by the way. Medium quality Jpeg should be fine.

Welcome man! I use those same arms to hold my backgrounds.


I personally use an alligator clip on an xyr stage on a precision lab jack. I find flexy arms are not reliable enough at high magnifications; something with precise controls saves headaches and time (definitely time).

Hi there houstontx,
I only use clay. Easy to get in any toystore.
This is useful for pinned insects. Position it just the way you want.
Kind Regards

Depending upon the subject, I use clay or a DIY third hand made using stiff electrical wire a small carpenter's clamp and an alligator clip.

The third hand works well with light subjects, not much heavier than a 3/8" washer. There's too much movement with heavier objects.

For heavier objects, I prop them up with the clay molded to stay out of the picture. I haven't tried using it to hold a needle yet.

I use a stage rather than a flexible arm .. I find it easier this way .. very easy to place a background...

Image

the stage allows me to lay several diffusers very easy

Image

for a specimen holder I use a ping-pong ball, cut in 2 halves, filled with plasticine (to make it heavy) and taped back to original position ... the ball over a metal ring ... this is a very chaeap way to have tilt and rotation virtually in any direction and makes tunning the insect positioning very easy
