Leja counting chamber slides are disposables created for sperm counting and motility analysis.

Although, they were developed to be used with sperm, they can be also used for the concentration assessment of other cellular elements, as microalgae, or any other cell suspension.

There are several counting chamber formats available for the concentration and motility assessment.

Leja for SCA®

Slides optimised for SCA®

Features:
– 10 micron – 4 chambers
– Appropriate for human sperm analysis
– Reference: 10.4.25

Easily operated

Leja permits to easy load the sample into the chamber and start a fast counting process.

Sample is distributed for capillary action homogenously.

As they are disposable, no washing is required, avoiding any contamination or influence due to the re-use effect.

Adaptable

The counting chambers are present into different formats to accommodate user´s needs. Find some examples:

> 10 microns depth chambers are the most appropriate for human and stallion sperm analysis as allow having all the spermatozoa focus in one layer. They can be of 2 or 4 chambers.

> 20 microns depth is present in formats of 2, 4 or 8 chambers per slide. This is the best configuration for most of the animal species.

> 100 microns chambers are the format for vasectomy analysis and toxicology (Rat and mouse sperm analysis).

Uniqueness

Sperm viscous samples are also easily inserted into the chamber, and can actually be used to determine the viscosity value by measuring the time needed to fill the chamber.

One of the main advantages is the special coating that in one side ensures that no air bubbles will be present when loading the sample, and on the other has very low toxicity level.
