Description

Rankin Bluing Reagent is buffered to a pH of 8; this closely controlled pH balanced solution provides consistent and rapid bluing of hematoxylin-stained nuclei without the risk of losing tissue sections from slides. It also allows for a higher throughput of slides. High pH bluing reagents may detach tissue sections from slides, this becomes a critical factor with frozen sections when limited tissue sections are available.

This pH-balanced bluing reagent enhances nuclear chromatin detail and initiates an insoluble dye-lake complex with nuclear chromatin, resulting in a permanent crisp blue-purple stained nucleus. It is universal and may be used with progressive and regressive hematoxylin stains.

When using the Rankin Bluing Reagent with a standard staining protocol, only thirty seconds to one minute exposure time is required and a one-minute water rinse after bluing. When used for frozen sections, a reduced time of five to ten seconds is sufficient with a water rinse of only twenty seconds. The time required for this reaction is significantly less than standard bluing reagents making it ideal for use in frozen sectioning when time is a critical factor.

Our bluing reagent is a clear colorless solution that is stable for winter shipments in cold climates. It's not a concentrate and does not require diluting before use. Additionally, an antimicrobial agent is added allowing for a shelf life of two years.

Invisible sunscreen and the brightening really helps too. Can be glossy, but if you let it absorb into the skin for 30 mins and the blot some of it off it can help with the glossy ness

A greasy mess
SUPER greasy. I have dry skin and it was incredibly greasy for me. It didn’t dry down at all and felt like it sat/slid around on my face. Obviously goes on clear since it’s a chemical sunscreen. Vaseline gel-like texture in your hand and applies like a silicone barrier. That part makes a little sense since I think dimethicone is high on the ingredient list. Unscented and didn’t test under makeup. I wouldn’t recommend this to anyone and I don’t think I’d try it again, which is disappointing cause I was hopeful with this one after reading reviews! The glowing reviews versus my experience makes me think folks aren’t applying enough SPF to get adequate sun protection. I’m a skincare girlie so it’s always a half teaspoon for this face.

Works well, smells great, goes on easily
Sun protection factor: 15 Sun Protection Factor (SPF), Size: 6 Count (Pack of 2)
It smells good. It goes on easily with the spray bottle. It keeps me from burning while out biking. It's a good price. Overall, a very nice product that does what it should. We carry it in our bike packs and in the car when we know we'll be out in the sun all day. Doesn't feel heavy when sprayed on so it smooths over your skin very well. Keeps me from burning.
