ALZET pumps operate by osmotic displacement. An empty reservoir within the core of the pump is filled with the drug or hormone solution to be delivered.

Due to the presence of a high concentration of salt in a chamber surrounding the reservoir (but isolated from it by an impermeable layer), water enters the pump through its outer surface (a semipermeable layer).

The entry of water increases the volume in the salt chamber, causing compression of the flexible reservoir and delivery of the drug solution into the animal via the exit port.

 

 

Privacy Policy

Welcome to www.alzet.com. This site is owned by DURECT Corporation. Privacy is very important to us. We also understand that privacy is very important to you. This Privacy Policy is designed to inform you about our practices regarding collection, use and disclosure of information that you may provide via this site. Please be sure to read this entire Privacy Policy before using or submitting information to this site

Use and Disclosure Information
Except as otherwise stated, we may use your information to improve the content of our site, to customize the site to your preferences, to communicate information to you (if you have requested it), for our marketing and research purposes, and for the purposes specified in this Privacy Policy.

We do not sell, rent, trade or otherwise market your information (demographic, contact, or otherwise) with ANY third party. Your information remains solely in our possession.

Your Consent
By using this site, you agree with the terms of this Privacy Policy. Whenever you submit information via this site, you consent to the collection, use and disclosure of that information in accordance with this Privacy Policy.

About Children
This site is not intended for children under the age of 13. We will not knowingly collect information from site visitors in this age group.

Active Information Collection
Some areas of this site may require you to submit information in order for you to benefit from the specified features (such as requests for information packages or special promotions). You will be informed at each information collection point what information is required and what information is optional.

Passive Information Collection
As you navigate through our Web site, we may collect your Internet Protocol (IP) address and navigational data. An IP Address is a number assigned to your computer by your Internet service provider so you can access the Internet and is generally considered to be non-personally identifiable information, because in most cases and IP address is dynamic (changing each time you connect to the Internet), rather than static (unique to a particular user's computer). We use your IP address to diagnose problems with our server, report aggregate information, determine the fastest route for your computer to use in connecting to our site, and administer and improve the site. We use your navigational data (“log files” and “server logs”) for system management to improve the content of the site, market research purposes, and to communicate information to visitors.

This site DOES NOT use session cookies, nor persistent cookies.

Access and Correction
To keep your personally identifiable information accurate, current and complete, please contact us as specified below. We will take reasonable steps to update or correct personally identifiable information in our possession that you have previously submitted via this site.

Security
We take reasonable steps to protect your personally identifiable information as you transmit your information from your computer to our site and to protect such information from loss, misuse, and unauthorized access, disclosure, alteration or destruction. You should keep in mind that no Internet transmission is ever 100% secure or error-free. In particular, e-mail sent to or from this site may not be secure, and you should therefore take special care in deciding what information you send to us via e-mail.

Links to Other Web Sites
This site contains links to other Web sites. Please be aware that we do not control other Web sites and that, in any case, this Privacy Policy does not apply to those Web sites. We encourage you to read the privacy policy of every Web site you visit.

Opt Out/Opt In
DURECT allows users to opt out from receiving e-mail communications from us. Users may unsubscribe at any time by sending an email message to alzet@durect.com with the word “Remove” in the subject line.
