[配件] 電刺激產生器 Stimulators

產品型號: FE155
廠牌名稱: ADInstruments
軟體控制的恆流刺激器,需與PowerLab搭配使用(另外購買),用於體外組織樣本的直接或電場刺激。
另外分離的刺激物選項也可用於活體動物和人體上神經和肌肉刺激的研究。

產品特點

此產品為配件,需搭配PowerLab生理訊號記錄系統使用

 

兩種型號的刺激器皆可供體外實驗使用,惟刺激隔離器(Stimulus Isolator)也可應用於體內實驗,如人類神經與肌肉刺激等
• 刺激器與PowerLab是藉由積體電路匯流排進行訊號交換,兩者間還需BNC纜線進行類比輸出
• 刺激器皆為電氣隔離,且可由LabChart調控恆流脈衝:
    ◦ 間隔:10μs ~ 4ms
    ◦ 脈衝頻率:體外:0.1 ~ 30 Hz
                          體內:0.1 ~ 2000 Hz
    ◦ 脈衝振幅:體外:最高達100 mA
                          體內:最高達10 mA

 

產品規格

Stimulator HC

Output

  • Connection type: Two 2 mm touch proof safety plugs
  • Output configuration: Constant-current stimulator with hardware limited repetition rate
  • Output waveform: Rectangular, monophasic pulses with software selectable pulse amplitude and duration
  • Isolation rating: 4000 V ACrms for 1 minute
  • Safety indicators: A single multi-color indicator displays the Stimulator HC status. A green flash indicates delivery of a valid stimulus. A yellow flash indicates an out-of-compliance condition (OOC).
  • Safety switch: Isolating On-Off switch flicks down to disconnect quickly
  • Compliance voltage: 100 V fixed
  • Current ranges: 1 mA, 10 mA, 100 mA full scale
  • Current rise time: <1 μs (100 Ohm load @ 100 mA) 25 μs (10 kOhm load@ 0.5 mA)
  • Current fall time: <1 μs (100 Ohm load @ 100 mA) 25 μs (10 kOhm load @ 0.5 mA)
  • Note: Rise and fall times are proportional to load resistance and capacitance.
  • Operating duty cycle: up to 20%
  • Resolution: 1% of full scale (10 μA, 100 μA, or 1 mA)
  • AC line leakage current: <200 nA p–p
  • Differential output noise: <1 μA p–p
  • Output capacitance: ~70 pF (without cable)
  • Power source: Non-isolated circuitry supplied by PowerLab via I2C connection. Isolated and high-voltage circuitry derives power from the external 12 V AC, 300 mArms, wall-plug transformer. High voltage isolation is provided by an internal isolation transformer. No batteries required.

Pulse Control (internal pulse duration control)

  • Pulse duration range: 0.02 to 5.12 ms in 0.02 ms steps
  • Duration accuracy: ±0.01% +5/-0 μs
  • Repetition rate: up to 30 Hz
  • Repetition accuracy: ±0.1% (determined by PowerLab)
  • Current rise delay: 22–45 μs (variable)

Control Port

  • I2C port: Provides control and power
  • Interface communications rate of ~50 kbits/s

Physical Configuration

  • Dimensions (h × w × d): 55 mm × 120 mm × 260 mm (2.2" × 4.7" × 10.2")
  • Weight: 1.3 kg (2 lb 15 oz)
  • Operating temperature range: 5–35 °C, 0–90% humidity (non-condensing)

ADInstruments reserves the right to alter these specifications at any time.

 

Stimulus Isolator

Output

  • Connection type: 2 × 4 mm (0.16") shrouded banana plugs

  • Compliance voltage: 100 V fixed
  • Current ranges: 100 μA, 1 mA, or 10 mA full scale
  • Current rise time: <1 μsec (1 kΩ load @ 10 mA) 25 μsec (100 kΩ load@ 0.5 mA)
  • Current fall time: <1 μsec (1 kΩ load @ 10 mA) 25 μsec (100 kΩ load @ 0.5 mA)
  • Operating duty cycle: up to 20%
  • Resolution: 1% of full scale (1 μA, 10 μA, or 100 μA)
