Cover Slides x100

We aim for next working day delivery for most orders placed before 2:30 pm, Monday to Thursday, provided the item is in stock. For live fish, we use a specialised DX overnight courier service, available Monday to Thursday.

While the delivery itself is next day, please note that livestock orders require a minimum of 24 hours' notice before dispatch. Please be aware that all deliveries rely on third-party couriers. While we do our best to ensure timely arrival, we cannot be held liable for any delays. Someone must be present to sign for livestock deliveries.

For full details on our delivery services, including specific charges and our DOA policy for live fish, please read more about our delivery policy.

At Exclusively Koi, we offer a 28-day return policy on most items, provided they're unused and in their original packaging. Please note that livestock is non-returnable due to biosecurity reasons. If you need to start a return or have received a damaged/incorrect item, contact us at info@exclusivelykoi.co.uk.

For full details on our returns process, including information on exchanges and refunds, please refer to our returns policy.

A microscope glass slide is a thin flat piece of glass around 24 mm x 60 mm. Your mucus sample from the koi goes on to the glass slide and then the cover slip (around typically 22 mm x 22 mm x 1 mm thick), goes over the sample. The glass cover slips are used to hold the mucus sample in place for examination under a microscope.

Typically both the glass slide and cover slip are placed together under the microscope for viewing.
