Leja slides are high quality disposable counting chambers especially made for semen analysis. Due to its characteristics, Leja slides will save time performing a semen analysis, as well as increase the level of accuracy and precision.

Leja, a Dutch company founded in 1995, invented a special technique concerning screen-printing; with a resin containing spacers. By doing this, a chamber consists of defined chamber depth. All slides are covered with a special coating to prevent air bubble formation and to prevent sticking of the semen to the chamber surface. Both resin and ink are non-toxic.

The Leja slides have an excellent low limit of quantification and can handle high sperm concentrations. There is a direct clinical impact: you will be very well equipped to determine the thresholds for the various modalities of Assisted Reproduction Technologies (waiting for natural conception, IUI, IVF or ICSI) and in the decision which treatment is optimal for a couple.

Because of high accuracy and precision of the Leja chambers, your results can be compared to other laboratories, which allows combining scientific data concerning the relationship between semen parameters (concentration, motility, viscosity) and fertility.

During the production process there is a continuous quality control of the slides (chamber depth between defined limits, no air bubble formation during filling and not toxic for boar semen). A certificate of analysis is provided with all slides.

All Leja slides have the following product qualities:

The Leja slide is made using non-toxic glue, ink and coating. Samples therefore remain viable and can be counted for up to 45 minutes after loading the chamber.

No bubbles.
Due to the consistently accurate chamber depth and specially developed coating, no air bubbles will occur when the Leja slide is loaded with a sperm sample.

Less diluting.
Leja slides have a specially designed air vent that allows even viscose samples to spread evenly throughout the whole chamber.
