1. Who We Are
This Cookie Notice applies to websites operated by LGC LIMITED – Company number 02991879 (collectively referred to as “LGC”, “we”, “us” and “our”). We are a global leader in life science tools, partnering with customers to find solutions that diagnose, treat, feed and protect our growing population.
LGC’s registered address is: The Priestley Centre, 10 Priestley Road, Guildford GU2 7XY.
For the purposes of the UK General Data Protection Regulation (“UK GDPR”), the EU General Data Protection Regulation 2016/679 (“EU GDPR”) and the Data Protection Act 2018, LGC is the data controller of the personal data processed through cookies on this website. LGC’s ICO Registration Number is Z7494404. For full information about how LGC processes your personal data, including the categories of data we collect, the purposes for which we use it, and your full range of data rights, please see our Privacy Notice, available at: https://www.lgcgroup.com/privacy-notices. This Cookie Notice should be read alongside our Privacy Notice.
This Cookie Notice explains what cookies are, how we use them on this website, what choices you have, and how to contact us if you have any questions.
2. What Are Cookies?
A cookie is a file containing an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
Cookies may be either “persistent” cookies or “session” cookies: a persistent cookie will be stored by a web browser and will remain valid until its set expiry date, unless deleted by the user before the expiry date; a session cookie will expire at the end of the user session, when the web browser is closed.
Cookies can be set either by us directly (these are called first-party cookies) or by third-party organisations whose services or features we have integrated into our website (these are called third-party cookies). Third-party cookies are set by a domain other than our own, and the third-party provider may have access to and use of the information collected by those cookies, including for their own purposes.
3. How We Use Cookies
We use cookies on this website for the purposes set out below. Where cookies require your consent, we will ask for it via our cookie banner when you first visit this website. You can manage or withdraw your consent at any time using our cookie management tool – see Section 6 below.
We use the following categories of cookies:-
3.1 Strictly Necessary Cookies
These cookies are essential for the website to function and cannot be switched off in our system. They are usually only set in response to actions you take, such as logging in, filling in forms, or setting your privacy preferences. You can set your browser to block or alert you about these cookies, but if you do, some parts of the website will not work as intended.
These cookies may be first-party (set by LGC’s domain directly) or third-party (set by a provider of a core functionality tool, such as a live chat service). Where they are set by a third party, that is indicated in the schedule below.
These cookies are exempt from the requirement to obtain consent under UK PECR, as they are strictly necessary to provide a service requested by you.
3.2 Analytical/Performance Cookies
These cookies allow us to count visits and understand how visitors move around our website, including which pages are most and least popular and how visitors navigate the site. The information these cookies collect is used to improve the way the website works. These cookies may be first-party (set by us directly) or third-party (set by an analytics provider acting on our behalf).
Where analytics cookies are used solely to measure website audience, the data is not used for any purpose beyond this, and the service is operated solely on LGC’s behalf (with appropriate safeguards in place), those cookies may be deployed without prior consent but you may still opt out at any time. This is indicated in the schedule. For all other analytical cookies, your consent is required.
3.3 Functional / Preference Cookies
These cookies enable enhanced functionality and personalisation, such as remembering your language or region preferences. They may be set by us (first-party) or by third-party providers whose services we have added to our website. If you do not permit these cookies, some or all of these enhanced features may not function correctly.
3.4 Marketing / Targeting Cookies
These cookies are set through our website by our advertising partners (third-party providers). They may be used to build a profile of your interests and show you relevant advertisements on other websites. They do not store directly personal information, but work by uniquely identifying your browser and internet device. These are third-party cookies.
