產品介紹

INTRODUCTION >> Counting Chambers

Sedgewick Rafter and Cover Glass — S50, S51, S52

For use in water analysis, culture inspection, and any fluid where particles per unit volume need to be determined. Available in two versions:

S50 is an economically priced plastic cell.
S52 is made from glass, with a chromium surface image. This is intended for professional use and when using phase contrast. In each type, a central cell is filled with fluid and a coverglass limits the volume to 1 milliliter. The grid subdivides this into micro-liters.
S51 is the spare cover glass for S50 and S52. Each cell is supplied with one cover glass.

Sedgewick Rafter 計數盤(Sedgewick Rafter Counting Chamber)是一種專門設計用來在顯微鏡下計算液體中微小顆粒或微生物的工具,廣泛應用於環境監測、生物學研究、水質分析等領域。

主要用途

  • 浮游生物計數:特別適合用來計算水樣中的浮游藻類、原生動物等微生物數量。
  • 水質分析:在飲用水、湖泊、河流或海水樣本中檢測微生物濃度。
  • 微粒濃度測定:可用於統計單位體積液體中的懸浮微粒或細胞數量。
  • 培養液檢查:用於觀察微生物培養液中的細胞密度與分布情況。

結構與特性

  • 標準容量:計數池通常為 1 mL 容積,計算區域為 50 mm × 20 mm × 1 mm,剛好為 1 立方公分。
  • 格子設計:底部刻劃為 1000 格,每格體積為 1 微升(μL),方便統計與換算。
  • 材質選擇:有玻璃與塑膠版本,玻璃適合重複使用,塑膠則適合一次性或有限次使用。
  • 觀察便利:搭配厚蓋玻片使用,可在顯微鏡下清晰觀察樣本分布。

使用建議

  • 在計數前,讓樣本靜置約 15 分鐘,使微生物或顆粒沉降至底部,有助於準確計數。
  • 適用於細胞密度低於 10,000 cells/mL 的樣本;若密度更高或細胞較小,建議使用血球計數板(Haemocytometry Counting Chambers)。

S50

S50 Plastic Sedgewick Rafter Counting Chamber

Sedgewick Rafter Counting Chamber in Plastic. Includes 1 cover glass.

An economically priced cell, for one time (or possibly several time) use and for educational/training exercises. Used widely in water analysis, culture inspection and for other applications where particles per unit volume in fluid must be determined.

Overall Dimensions 76mm x 40mm x 2mm thick
Volume 1ml
Chamber Dimensions 50mm x 20mm x 1mm deep
S51

S51 Spare Coverglass

Coverglass for Sedgewick Rafter Cells S50, S52 and S53

Spare Suitable for S50, S52 and S53
S52

S52 Glass Sedgewick Rafter Counting Chamber

Sedgewick Rafter Counting Chamber in Glass. Includes 1 cover glass

Reusable tool for the professional user. The cell is made of high quality optical glass with a chromium surface image. It is intended for continued professional use and whenever using phase contrast. Used widely in water analysis, culture inspection and for other applications where particles per unit volume in fluid must be determined.

Usage Note:
When using Lugols, we advise to clean the cells as soon as the analysis is complete and dry them thoroughly, preferably without heat (as thermal coefficient of glass and metal frame are different). This will help extend their life. Obviously the use of any acids or solvents could cause breakdown of the cement used.

Overall Dimensions 76mm x 40mm x 2.28mm thick
Volume 1ml
Chamber Dimensions 50mm x 20mm x 1mm deep
S53

S53 Plain Glass Sedgewick Rafter Counting Chamber (No Grid)

Sedgewick Rafter Counting Chamber in Glass. Plain version with no grid pattern. Includes 1 cover glass.

Reusable tool for the professional user. For many applications, particularly where larger plankton are being analysed, there is no requirement for a counting grid printed onto the slide, hence the introduction of this slide with a plain glass base. This chamber can be used with either upright or inverted microscopes.

The S53 can be used in conjunction with an eyepiece reticle, such as a Whipple grid (NE29), where detailed counting/sizing is required.

Overall Dimensions 76mm x 40mm x 2mm thick
Volume 1ml
Chamber Dimensions 50mm x 20mm x 1mm deep
