Bubbles in perfusion systems are caused by solution temperature changes. As solutions warm, they cannot hold as much gas, so they off-gas. This forms bubbles in perfusion tubing. It is especially true in inline heaters where the temperature rises dramatically. The best cure for bubbles is to pre-warm your solutions. AutoMate Scientific introduces the BubbleStop™ Syringe Heater with integrated temperature sensor and feedback. S…

Brownlee's rugged yet easy-to-use amplifiers have four channels of a high gain/low noise amplification, lowpass filter and output offset control. A control knob adjusts amplifier parameters, and an alphanumeric LED readout displays values. There is a memory function for each channel. Input voltage noise is only 1.5µV rms.The Brownlee Precision Model 410 is a four-channel general purpose laboratory amplifier (one channel shown)…

In addition to the Model 410 amplifier's features, the Model 440 offers an 8-pole Bessel lowpass filter, auto-zeroing, a line notch filter, highpass filter, multiple memories per channel, and a digital voltmeter on 2 channels. A wide bandwidth of over 500 kHz at all gains insures smooth recordings.The Brownlee Precision Model 440 incorporates four channels of sophisticated amplifier and filter circuitry in a friendly easy-to-u…
