  • Buret w/ PTFE Stopcock
    Quick shop

    The buret is made of acrylic for durability, and has a polytetrafluoroethylene (PTFE) plastic plunger stopcock for resistance to chemicals, moisture, and high temperatures. Acrylic is lightweight, and resists shattering, impact, and most non-abrasive cleaners including ammonia and strong detergents. PTFE plastic is a strong, low-friction material that has smooth transfer, high surface release, and nonstick properties. It has high chemical resistance, and resists moisture, high temperatures, flames, thermal expansion, and ultraviolet (UV) exposure. PTFE has low temperature toughness. The buret has 50.0mL capacity with 0.10mL graduation

    Copper Sulfate, Crystal form. Used to make liquid solutions.

    This material is used to remove hydrogen sulfide and other reduced sulfur compounds which are the source of 'rotten egg' like smells. For best results use as soon as possible after the end of fermentation, if racking the wine once or twice during fermentation didn't elimate the problem. Avoid adding excess copper. Use bench tests to determine the minimum effective dose. We also offer Residual Copper Analysis testing as well as Copper Trials to determine the appropriate amount to add.

  • Deluxe pH Meter PH56
    Quick shop

    PH55 Waterproof pH tester with large dual-level LCD that displays pH and temperature (°C or °F). The large display shows readings in an extended range from -2.00 to 16.00 pH and simultaneously shows temperature from -5.00 to 105.00°C or 23.00 to 221.00°F.

    pH55 has a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. Complete with a temperature probe for faster and more precise temperature measurement it compensates automatically for temperature.

    Calibration is made automatically in 1 or 2 points with memorized standard and NIST buffer sets. Auto power OFF saves battery power after non-use. The double-junction electrode can be replaced in a very fast and simple way! The modular design allows easy electrode and battery replacement.
