Product Development Update: Launch of the SPP-100 Extracellular Amplifier/Filter
Product Development Update: Launch of the SPP-100 Extracellular Amplifier/Filter


Key Features:

  • High Signal Gain: Amplification up to x20k for precise signal acquisition.

  • Flexible Filtering Options: High-cut, low-cut, and 50/60Hz notch filters for optimal signal clarity.

  • Remote Headstage: Manipulator-mounted for convenient placement during experiments.

  • Cost-Effective Standalone Design: Operates with an external DC power supply, making it an economical alternative to the modular NeuroLog System when single-signal recordings are required.

  • Broad Compatibility: Suitable for life science research labs and teaching environments,

compatible with commercially available data acquisition systems.


Versatile Recording Capabilities

The SPP-100 supports extracellular single-electrode recordings using high-impedance metal or glass microelectrodes. It is equally suited for differential recordings from paired gross electrodes such as nerve hooks. For added flexibility, Digitimer offers a range of electrode adapters and micro-pipette chambers.


Note: The SPP-100 is not a medical device and lacks isolation, making it unsuitable for human applications.


Small Product Platform (SPP) Concept

The SPP-100 is the first in a new line of products developed under Digitimer’s Small Product Platform (SPP) initiative. This modular design approach enables rapid development of new instruments by reconfiguring a shared power supply, display, and control interface with product-specific circuit boards.


Components and Accessories

SPP-100 Headstage (SPP-100HS)

  • Compact, anodized metal design with a 2m pre-wired cable and 4-pole Lemo connector.

  • Removable aluminum rod for micromanipulator mounting.

  • Input sockets for +INP electrode (2mm), -INP reference electrode (1mm), and COM/Ground (1mm).

  • Accessory kit includes input connectors and a "U"-shaped jumper for single-ended recordings.


Main Amplifier/Filter Unit


  • External power supply input and BNC signal output connection.

  • Adjustable brightness LCD screen displays gain and filter settings.

  • Multi-function rotary encoder and push-button controls.

  • Fold-out feet for an alternative viewing angle.


Trial and Evaluation Opportunities

Digitimer is pleased to offer short-term loans and user evaluations of the SPP-100. While there is no obligation to purchase, we welcome feedback from trial sites to help enhance the product and explore additional features.


If you’re interested in testing the SPP-100 for your extracellular recording applications, please contact Digitimer North America for more information.
