• Nitrogen Solubility Apparatus

Nitrogen Solubility Apparatus

Determines the dispersible nitrogen in soybean products under the conditions of the test. In contrast to the alternate fast-stir method for Protein Dispersibility Index (PDI), AOCS Official Method Ba 10-65, the slower stirring technique used in this method will give generally lower results. Applicable to ground soybeans, whole or ground full-fat and defatted soy flours and grits, and soy-bean meal.

  • Conforms to AOCS Ba 10-65
  • Six sample testing capability
  • Microprocessor controlled high accuracy temperature control
  • Digital Tachometer for adjustable stirrer speed

Constant temperature bath with stirrers for nitrogen solubility tests. Stirs sample-water mixtures up to 120 RPM and controls temperature with ± 0.5°C (± 1°F) stability. Immerses test beakers at the proper depth per AOCS specifications. Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by an over-temperature control circuit that interrupts power should the bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Stainless steel stirrer paddles are driven by a ball bearing type motor through an improved pulley driveroller bearing arrangement. Paddles can be raised and lowered for placement of sample beakers in the bath. Stainless steel bath includes perforated support shelf for beakers. Long-lasting polyester drive belt improves reliability. Drive train components are protected by a removable steel guard. All exterior surfaces have stainless steel or chemical resistant polyurethane enamel finishes.
