Polypropylene containers are autoclavable. The recommended autoclave cycle for empty containers is 121°C at 15 psi for 20 minutes. Care must be taken to allow free air circulation into and out of vessels during the autoclave cycle, .Polypropylene containers are autoclavable.

I have a tropic Marine hydrometer that reads 1.24 salinity at 78 degrees water temp. I also have a freshly calibrated hydrometer that reads a solid 37 - converted to 1.26. I know it may not matter but it bothers me. Calibration fluids came with the hydrometer and are at room . A refractometer is likely a better choice than a hydrometer. Before the hydrometer crowd jumps in and claims that you can get perfectly good results using a hydrometer too, yes, . I have a tropic Marine hydrometer that reads 1.24 salinity at 78 degrees water temp. I also have a freshly calibrated hydrometer that reads a solid 37 - converted to 1.26. I know it may not matter but it bothers me. Calibration fluids came with the hydrometer and are at room temperature 72 degrees. Is the shift this high for temp?
A refractometer is likely a better choice than a hydrometer. Before the hydrometer crowd jumps in and claims that you can get perfectly good results using a hydrometer too, yes, that's also accurate. In terms of usability and precision, I think that refractometers have an edge over hydrometers.
Hydrometers are calibrated to be most accurate when the water is 77°F (25°C). While hydrometers are still used today, many reef aquarists have made the switch to a refractometer. So, if you're considering the switch, here’s what you need to know about saltwater refractometers and how to use them. Hydrometers are inexpensive but cannot be calibrated and you must pay careful attention to the water temperature. Analog refractometers are the mid-range price point and the most popular choice because they can be calibrated which means you . Benefits to Using a Refractometer versus a Hydrometer. After temperature, Salinity is the most important measurement of seawater you can make for your tank. Therefore, refractometers and hydrometers are the most used tool in the hobby, or at least they should be.
Hydrometers & Refractometers. Salinity is one of the most fundamentally important water parameters we track in our saltwater aquariums. There are several ways to measure salinity or specific gravity. Hand-held refractometers are popular due to their ease of use and low cost, but digital salinity testing devices are gaining popularity. I've had the Hanna HI98319 Salinity Pen, a Amazon White-Label refractometer, the Milwaukee MA887 digital refractometer, a VeeGee STX-3 & now the Misco Aquar-H2O digital refractometer. Years ago I even had the Instant Ocean Swing Arm Hydrometer.Every saltwater aquarium requires a testing instrument to measure the salinity (salt level) of the water. To do so you will need either a hydrometer, such as the Coralife Deep Six Hydrometer, or a refractometer, such as the Red Sea Seawater Refractometer. There are two items typically used by the home aquarium keeper to measure salinity, the swing-arm hydrometer and the refractometer. Each one of them measures the salinity or specific gravity of the water sample, but each of them does it differently.
Measure salt water or salinity of water, ideal for aquariums and marine monitoring. Measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand. Features automatic temperature compensation. Comes with hard case, dropper, screwdriver, user .
