MicroJek produces the world's smallest commercially available microinjection needles. They have proven, in numerous trials, to drastically improve the viability of specimens, allowing experiments in arenas that were prevoiusly unavailable. Partner with MicroJek on your research project today! 

IMPROVED VIABILITY — MicroJek needles have empirically brought maximal obtainable cell viability from 55% to 90%, and from 35% to 81% for cytoplasmic and nuclear injections, respectively. Find the best needle for your research!  

MICROJEK IS THE SUPERIOR ALTERNATIVE — The industry leader's smallest needles have an OTD of 0.7 µm +/- 0.2, compared with MicroJek's 0.2 µm +/- 0.05…This is a leap forward in tip size, variance, & resulting specimen viability. Order now! 

TYPES OF NEEDLES AVAILABLE — Select 0.2 µm StemJek, 0.3 µm InJek or EggJek, our 0.5 µm outer tip diameter needle designed for pronuclear and RNA experiments. Needles are available in different tip lengths, depending on the type of research.  Tip length allows varying flexibility and flow control. Request Samples!

CUSTOM NEEDLE DEVELOPMENT & PARTNERSHIP — MicroJek  can develop needles specific to your life sciences, agro-science and micro-electronics programs. Contact us to find out how we can develop a custom needle for your project or research.
