microinjection needles -- which ones to order?

Model Organism: Worms Scientific Discussion

Which microinjection needles do you use? We have been using the following, but the company says they have been discontinued.

Dagan Corporation
FLG10
OD=1.00mm
ID=0.75mm
softens at 821°C
200 Pieces
10cm long
prism glass capillaries
612-827-5959 www.dagan.com

I think these needles have an internal filament but this is not indicated on the packaging. Perhaps there is an equivalent from the same company?

Thanks,
Morris

Hiya Morris,

We’re using capillaries from FHC (Catalogue #30-31-0):

Borosilicate (Pyrex)
1.2mm OD x 0.9mm ID/Fiber
100mm long
Omega dot fiber for rapid fill

They work quite well.
