6 Pint Polypropylene Lab Jars and Closures – $20.92, New Record Low


This 6 pack of polypropylene lab containers and lids has sold for up to $40.27 in the last month.  In that time it has averaged $36.06.  Several price drops have brought it down to a new record low Amazon price of $20.92.  That figures to $3.49 each.  These can be used up to autoclave temps.

Uses include: Yeast rehydration, yeast washing and slurry storage. Also an easy vessel for making and storing sanitized water.  I use similar containers to rehydrate yeast.  Check out Tip 1 on our Tips Page for more info on that.

12 Stainless Portion Cups – $6.65, Record Low, 55 Cents Per Cup

This highly rated pack of (12) 2 1/2 Ounce Stainless Steel Portion Cups has recently sold for as much as $10.86.  They have dropped to $6.65.  This figures to 55 cents per cup and is a record low Amazon price.  

These are very similar to the cups that I use in my Brew Day Box.  I use those to portion out hops and other boil additions.  Others use these type of cups for pH and gravity sample containers.  They are a great size and don’t take a lot of room since they nest together.  The ones I have cost about $1.50 each plus shipping.

Gravity to Brix Accuracy
Typical refractometers use a linear 4 x gravity to Brix conversion.  That’s fine and dandy up until around 1.049.  At that point this linear scale starts to become inaccurate.  Brix 11 does equal 1.044, but Brix 12 does not equal 1.048.  It is 1.049.  It’s only 1 point off here, but up at Brix 24, it’s up to 5 points off.  Brix 24 equals 1.101 not 1.096.

All this to say that this model of refractometer uses a more accurate, non-linear gravity to Brix scale.

From the manufacturer: “This is the only inexpensive Wort SG to be corrected. The only other corrected refrafractometers in existence are the BREWfractometer and the BREWfractometer Extreme.”

Refractometers can be used to measure gravity throughout the brewing process.  You can also estimate the alcohol content of your beer if you forget to take an OG with the use of a refractometer and a hydrometer.  Check out Northern Brewer’s Refractometer Calculators.
