STX4 EVOM Electrode with Removable Blades for TEER in 6.5 mm InsertsElectrode for EVOM3 and EVOM Manual with Replaceable Blades Ensures Stable Measurements The STX4 electrode is the most recent version of chopstick electrode for the EVOM3 and EVOM Manual and it is designed to facilitate measurements of voltage (potential difference: PD) and resistance (transepithelial electrical resistance: TEER) of cultured epithelia (cellular layer) grown onto permeable membrane inserts in 12 and 24 well tissue culture plates. STX4

Electrode for EVOM3 and EVOM™ Manual with Replaceable Blades Ensures Stable Measurements

The STX4 electrode is the most recent version of chopstick electrode for the EVOM3 and EVOM™ Manual  and it is designed to facilitate measurements of voltage (potential difference: PD) and resistance (transepithelial electrical resistance: TEER) of cultured epithelia (cellular layer) grown onto permeable membrane inserts in 12- and 24-well tissue culture plates. STX4 can measure directly inside the well plates with 12 and 24 inserts. The STX4 is designed primarily for 24-well hanging inserts or transwells (e.g., Corning 3470), and the electrode’s best performance can be seen in this format.

Benefits

  • Replaceable blades – This new STX4 electrode has replaceable electrode blades.

  • No chloriding necessary – Electrode tips are specially coated, requiring no chloriding (maintenance step) to ensure proper electrode functionality when measuring TEER of cellular layers like epithelial cultures. Chloriding was necessary for the  STX2-PLUS.

  • Less liquid volume needed – This electrode requires with less liquid volumes than required for STX2-PLUS electrode to keep the tips immersed and able to provide stable readouts.

  • Hands-free operation – The STX4 electrode fits perfectly in 24-well hanging transwells cell culture well plates and can stay hung on top of these transwells, allowing for hands-free operation.

  • Greater precision – The STX4 electrode offers better TEER measurement precision, because it eliminates the variability factors resulting from change in electrode spacing and positioning as seen with STX2 electrode.

  • Shielded from radio frequency interference (RFI) – This STX4 electrode has a shielded cable and eliminates or minimizes any interference (from electrical sources or cell phones) affecting the TEER measurement read outs.

The STX4 electrode sits on the well for hands-free operation, and the adjustment ring lets you place the electrode blades in the well exactly where they need to be, suspended in solution without touching the membrane or the bottom of the cell culture well plate.

NOTE: Improve your TEER measurement precision with the older EVOM2 by swapping out the STX2 or STX3 with the new STX4. STX4 can be used with the EVOM2 (previous model) by using the EVM-AC-02-01-01 adapter, which is sold separately.

Perfect fit and great quality for the price
This suit was perfect for my son. The fit was exactly as expected. The quality is excellent for the price—it feels well made and durable enough to last through multiple wears. It doesn’t feel cheap or flimsy at all. It also looks really good on him. Clean, polished, and great for formal events like weddings or parties. Overall, a fantastic value with great quality and a great fit.

Missing items
Color: Sky Blue, Size: 16
Was missing the tie that is supposed to come with it and it looked like it was tried on and thrown back in the bag. The sleeve to the jacket were rolled up.

Excellent Quality, Great Value, Great Look. Highly Recommend
Very well-made, there are some minor imperfections in the cuff sewing that aren't really noticeable when on. Liner is quality, color is spot on, and it fits true to size. If you're in the market for a toddler blazer and pants, you can't go wrong with this one in terms of quality, price, and the cut is perfect for a very polished look. There were a few loose strings to be clipped, but everything was correctly sewn and well. None of them affected the seam strength. The pants have a button and elastic on the waistband to make adjusting the waist size easier.

Great boys slim fit suit for weddings, church, or special events
Color: Medium Grey, Size: 12
Great kids suit. Comes with a jacket, pants, and tie. Does not have a shirt. Fits as expected. Classic cut on the lapels. Great quality materials. Well made pants and jacket. The color is consistent without any fade or dark spots that can happen with lower quality fabrics. Looks great on. My son loves it. Says it is not restrictive, he can move easily in it. Highly recommend for church, special events, weddings, etc.

Nice high-quality, light weight suit for a tween!
Color: Navy Blue, Size: 10
This is such an attractive suit for a tween boy! My son loves dressing up, and this is his new favorite suit. He really likes the double-breasted style and the light weight of the fabric so that it isn't too hot. The tie that came with it gives major Harry Potter vibes which we weren't expecting, but he has lots of other ties that he also enjoys pairing with it. The size seems right, and it fits him well. He says it is very comfortable. I'm happy with the quality and the navy color.
