Perfusion Systems and Bath Chambers

• Reliable solution exchange for tissue oxygenation or pharmacology experiments
• 1, 4 or 8 fluid reservoirs
• Available for room temperature operation, inline-heated, or with both inline and bath chamber heating
• ValveLink8.3 and ThermoClamp Controllers compatible with SutterPatch® Software
• High reliability through low-maintenance pinch valves
• Electrically quiet circuitry for valve switching and temperature control
  
  

ValveLink8.3 Controller

• Low noise & low voltage valve control Designed for electrophysiology
• ValveGuard™ technology detects bad valves and prevents damage
• Run experiments automatically – even unattended
• Manual push buttons
• Red/green LED indicators
• 1.5 Amp, 12V AC supply included (specify 110V or 220V)
• Dimensions: 9.28 in x 1.6 in x 5.13 in
• Weight: 3 lbs | 1.4 kg
• Eight TTL inputs directly activate 8 valves or control 16 valves with only four digital outputs
• Analog input selects 8 valves
• Analog out "event marker" to record all valve activity
• Push buttons, TTL, analog and USB inputs ALL work
• Capable of switching valves in 1 millisecond
• Automatic networking of up to eight ValveLink8.3 units, connected to a USB hub and PC to create a single 64-channel controller.
• Capable of powering 12 watt (1 amp) valves and 24 watts (2 amps) total
simultaneously

Pinch Valves for reduced maintenance

• Easiest valves to clean and switch tubing
• Liquids never touch the valves
• 20 millisecond switching
• 1/32” ID silicone tube passes through and is pinched closed by solenoid activation
• Individual indicator LEDs
• Aluminum enclosure keeps the valves dry from spills and offers Luer lock ports for syringe reservoirs

ThermoClamp-3.1® or ThermoClamp-3.2®

• Auto-tuning PID (Proportional Integral Derivative) temperature control accurate to <1.0°C (often ±0.1°C) with fuzzy logic
• Extremely low noise (analog heating) designed for electrophysiology
• Over-temperature protection
• Three types of user-configurable thermal runaway protection (patent pending) with fuzzy logic constraints
• Smart voltage setpoint: digital, analog (BNC) or automatic
• Separate displays for both temperatures (control sensor and safety sensor)
• Constant USB/serial data stream output
• Automatic heater failure detection and prevention
• Utilization of the safety sensor as secondary input for feedback control
• Includes power supply, bath and safety sensors
• Ambient to 50°C
• Analog temperature output (100 mV/°C)
• Dimensions: 11.5 in x 2 in x 7 in
• Weight: 4 lbs | 1.8 kg

Inline Heater

• Combination inline heater plus multi-channel focal drug delivery
• Luer lock tube connections
• Steady 37°C at 5 mL/min flow rates through both the bath line and tip
• Designed for physiology research – No metal anywhere in the flow path
• Low noise for electrophysiology
• Internal and external grounding plus electrical isolation between liquids and heating elements

Heated QuickStage™ Bath Chamber

• Integrated spill channel
• Magnetic stainless steel tool platform holds your tubes and electrodes for the next experiment
• Release two thumb nuts to change coverslips and clean the entire stack
• Four heated and three unheated chambers available
• Adapters for 35 mm Petri dishes from Nunc, WillCo, Falcon, In Vitro, Corning, Mattek
• Standard 24 mm x 40 mm #1 thickness coverslip

Compressors
The pressurized perfusion systems (all 4- and 8-channel systems other than the gravity feed models AM-PS4 and AM-PS8) require a compressed gas. A popular source is air from a silent, industry grade compressor.
