Kinematic viscosity bath

Engineered for repeatable, high-throughput viscosity testing, the K23900 from Koehler Instruments delivers laboratory-grade temperature control and uniformity (bath stability ±0.02°C and uniformity ±0.02°C relative to set point) thanks to separate boost/control heaters, plus an internal low-turbulence stirrer and baffling, and it’s built to comply with ASTM D445 temperature requirements. 

The compact 7-port top (accepts seven glass capillary viscometers) holds a 21.6 L bath of recommended 10 cSt silicone oil and is designed to maintain a constant fluid level with up to seven viscometers so immersion depth remains consistent during loading/unloading; an integrated ½" overflow outlet prevents overfilling by draining excess fluid while low-fluid and over-temperature protection guard the instrument and samples (OTP limits operation to prevent exceeding 115°C).
