ALA Scientific pipette holders
MICRO-MÉCANIQUE offers the complete and configurable ALA Scientific range of electrode holders adapted to the type of amplifier, experimental configuration and compatibility with your pipette. You can also order customised models (glass diameter, connector, angle, materials, etc.).
Description of the ALA Scientific pipette holder
BNC type electrode holder (PPH-2P-BNC…)
- Compatible with HEKA, NPI, Dagan amplifiers (standard BNC connector)
- Polycarbonate body (Teflon available on request)
- Supplied with standard silver (Ag) wire, Ag/AgCl pellet option available
- For µ-pipette capillary glass with a standard external diameter of 1.5 mm (other sizes available)
- Options: head angle (0°, 30°, 45°, 90°), integrated infusion ports, custom materials.
Axon / Molecular Devices type electrode holders (AXU / AXP…)
- Compatible with Axon amplifiers (Axopatch 1, 200A, Axoclamp-2A…) via universal connector or specific Axon connector
- Same design: low-noise polycarbonate, Ag/AgCl option, 1.5 mm Ø glass available
- Similar options (angle, perfusion, materials).
Injection / Ejection electrode holders (IPH… Luer)
- Equipped with a lateral Luer screw junction for injection/ejection, aluminium handle for easy handling
- Compatible with various amplifiers depending on connector chosen (BNC, Axon, 2 mm pin…)
- Glass options (Ø 1.0 / 1.2 / 1.5 / 2.0 mm), angle, perfusion, materials available.
KCl Bridge Electrode Holder (PPH-KCL…)
- Stabilises electrode potential while excluding Cl- ions from the recording solution
- Includes a small quartz tube filled with KCl to act as a bridge between the AgCl pellet and the recording electrode
- Electrical characteristics (in 0.9% NaCl): Typical DC offset ~180 µV, Drift ~25 µV/h, Noise ~1 µVp-p
- Same adaptation options (connectors, angle, OD of glass).
Optopatcher
- Specialised system combining an electrode carrier and an optical fibre for optogenetic stimulation
- Compatible with BNC and Axon connectors; glass diameter on request.
