LMA - Multi Shank

Please enable JavaScript in your browser to complete this form.

GENERAL SPECIFICATIONS

The Multi-Shank LMA design is ideal for acute or chronic applications. Each shank can have up to 32 electrode sites, therefore multiple connectors may be needed. MicroProbes for Life Sciences may also employ the 36 contact Nano Omnetics connector, model A79022-001, which is also compatible with most headstage manufacturers.

You will need to specify the number of shanks (S) as well as the specifications associated with each prong. If no SS tube is required, which may be the case for chronic applications, then specify 0 for option (b).

Any number of channels in between will use the larger diameter tubing. For example, a 12 channel LMA with 12.5um contact sites will use a 0.018" OD tubing.

ACCESSORIES AND ADDITIONAL SERVICES

Do you require product pre-sterilization?
(Sterilization (ethylene oxide gas) will be performed by a third party and requires an additional fee to cover process, packaging, and shipping. Typical fee is $850 USD per batch. Process is not validated for human use.)
