microinjection syringe
 
--------------------------------------------------------------------------


We inject 1 cell stage embryos using a pulled glass capillary tube that is
attached to an air pressurized picospritzer. With the picospritzer we can
control the amount of time the air is released and (although we have not
measured this) also the amount of substance released from the needle.

Dear All
We would like to buy microinjection syringes to be used for
microinjection of zebrafish embryos. we have tried using the syringe with
a glass capillary tube as the needle but it did not work well, we could
not control the volume of solution injected, in addition to the problem of
easily broken needle. is there any commercially available microinjection
syringes with a metal needle that can deliver a
precisely determined volume of solution?? if the answer is no, then how
can we control the volume of solution injected? Thanks
