The BIRR disposable counting chamber BB2-V-20 is specially designed for the assessment of low sperm numbers, like check after vasectomy. Each of the two BB2-V-20 chambers contains a grid, dimensions 10,0 x 5,0 mm. The grid is divided in 5 blocks of 1.0 x 10.0 mm. To improve the finding of the grid the lines are extended at both side 1.5 mm.
The counting chambers are made of a standard microscopic slide and a cover slip. The chamber is made of a standard microscopic slide (L x W x H; 75.0 (±0.2) x 25.0 (±0.2) x 1.0 (±0.1) mm) and a cover glass (32.0 (±0.2) x 24.0 (±0.2) x 0.7 (±0.1) mm). As a result of our strong focus on quality, we managed to set a high standard on the consistency of the actual chamber height and the absence of toxicity. The actual chamber height and the non-toxicity of the slides are depicted in the quality sheet of a specific batch. Moreover our packaging limits the damage of moisture, and increase the shelf life of our counting chambers.
