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.

Alba packaging stinks
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Complete waste of money! I ended up tossing it out because it’s IMPOSSIBLE to use. You should be able to twist the top to lock/unlock and spray it. NOPE. The top just spins and doesn’t catch or you cannot twist it at all. It’s also virtually impossible to spray. I had to hold it against my torso and press with both thumbs to get it to spray. Meanwhile, it’s leaking, the bottle is getting slippery. And then the spray goes EVERYWHERE, it’s not a narrow spray but it’s as if you’re dusting crops. I tried to see if it needed a certain pressure point, two fingers, bloody hell it’s not a Magic Mouse you should be able to unlock and spray it with one hand. Anyway, Alba needs to do some QC on their packaging. The last pump lotion I got, the pump also did not work. It just spun and spun and could not be unlocked. I had to wash and reuse the pump from an old bottle.

Best sunscreen brand! Fair, sensitive-skinned and rely on this
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Alba Botanica is my favorite brand for sunscreen products and it checks all the boxes on my list: Excellent long lasting coverage, fine mist spray and easy coverage cream versions, great for my sensitive skin (no breakouts- I do NOT use it on my face though), the Hawaiian fragrance is pleasant, it’s reef safe (a big one for me as a snorkel/dive aficionado), and organic ingredients. The large size lasts 5 full days when on a boat all day in the Carribbean, and I only apply it twice (once in morning, and again midday.) I have fair skin, and I never burn. The spray version is, by nature of its aerosol capacity, a bit drying on the skin, but this is to be expected, and it creates a long lasting barrier. The cream version is a wonderful emollient, although not quite as long lasting. Best deal is only in the summer season at CostCo for a 2 pack... in my searches, Amazon has the best deal otherwise.

Perfect for Travel and Gentle on My Son's Skin!
Style: Spray (2 Oz)
First off, the size is perfect for going through TSA. We had no issues bringing it in our carry-on, which made traveling so much easier. The convenience of having a high-quality sunscreen that’s travel-friendly is a huge plus. What really impressed me is how gentle it is on my son's skin. He has sensitive skin that tends to dry out with other sunscreens, but this one kept his skin moisturized and protected all day. No dryness or irritation at all! And the smell is amazing! It has a pleasant, natural scent that isn’t overpowering. Applying it was a breeze, and the spray format made it quick and easy to cover all areas evenly. If you're looking for an effective, travel-friendly sunscreen that’s gentle on sensitive skin and smells great, I highly recommend the OOLA Organic Sunscreen SPF 30 Sunblock Spray. It's become a must-have in our sun care routine!

Smells great and works great too!
Style: Spray (2 Oz)
Great sunscreen and smells fantastic. Not sticky or greasy feeling, but the bottle seems a bit small for the price. Took it to the beach for the 4th of July week and it was the first time I didn't come back with my "base burn". So it really works well. Great size for carry-on travel, but again a bit pricey for the amount you get.
