hydrometer vs refractometer reddit|are all refractometers the same : advice During the course of this experiment, I look to test multiple methods for measuring specific gravity with the goal to compare accuracy and ease of use, as well as compare the pros and cons of each piece of equipment.
The extra pressure in an autoclave means that water boils at a temperature higher than its normal boiling point—roughly 20°C hotter—so it holds and carries more heat and kills microbes more effectively.

Most commonly used media are suitable for use with alamarBlue assays. Since the media is used in the blank, and also any other positive or negative control plates, any effects of the . See more
I use both, mostly refractometer on the hot-side and hydrometer on the cold. Might as well taste the fermenting/fermented beer along the way. refractometers are definitely far more .
Refractometer is used during lauter to monitor gravity of wort (first runnings and when to stop the transfer so you’re not over-extracting, diluting the wort, and pulling a bunch of tannins) . I use both, mostly refractometer on the hot-side and hydrometer on the cold. Might as well taste the fermenting/fermented beer along the way. refractometers are definitely far more convenient, especially for 1 gallon batches (speaking as a 1 gallon brewer myself). Refractometer is used during lauter to monitor gravity of wort (first runnings and when to stop the transfer so you’re not over-extracting, diluting the wort, and pulling a bunch of tannins) hydrometer to check pre-boil gravity, OG going into fermentor, and FG to ensure fermentation is complete. They are specific tools for specific uses. Hydrometers measure density, while refractometers measure refractive index. You can get an accurate reading with either before fermentation starts. Once you have that initial specific gravity/°Brix reading, you can use either + a calculator to .

First thing the guy asked was "how are you taking the readings, refractometer or hydrometer?" He then explained that refractometer is great for original gravity, but lousy for final gravity, especially in high alcohol beers. I took the reading with my . Refractometers are great for pre-fermentation gravity readings. Can't beat the convenience of pulling a sample straight from the MLT or kettle and not having to cool it first. You'll still need a hydrometer though for post-fermentation FG readings. Refractometers are pretty useless for that.

wine refractometer vs hydrometer
Hydrometers are always more accurate when used and calibrated properly, but the convenience of a refractometer during a brewday is pretty hard to beat. Keep in mind that many of the cheaper refractometers for sale are designed for . #1. Hey Brew dogs, Do most folks use the hydrometer or refractometer? I have used both. The hydrometer increases the risk of contamination and oxygen in my mind but I'm not sure the refrac is accurate even though I calibrated it with distilled water. What's your choice and why? Nosybear. Well-Known Member. Joined. Jul 16, 2012. Messages. 10,254. There are several advantages to using a refractometer instead of a hydrometer, especially in that the refractometer does not suffer from many of the same shortcomings of the hydrometer. Here are some examples of the advantages of a . On the refractometer, try using the Brix scale and then converting Brix to SG, and comparing the result to your hydrometer reading. I've often read that some refractometers have inaccurate SG graduations while the Brix scale is correct.

Loosen caps of containers of liquids prior to loading into the autoclave; sealed bottles may shatter or explode during pressurization. Never seal a liquid container with a cork or stopper.It is possible most PGRs are more effective when added after autocalving. You can use 0.2 micron millipore filter to add them.
