Description
Bacterial cell spreaders, L-shaped at 90°, are stainless-steel laboratory tools designed for even distribution of microbial suspensions across agar surfaces in Petri dishes. Each spreader measures L 195 × W 40 × Ø 4 mm, giving a compact L-profile that reaches the full plate radius while keeping the handle clear of the lid and rim. The rigid stainless-steel construction supports repeated flame sterilisation and routine cleaning between samples, making the instrument suitable for microbiology, molecular biology and cell-culture workflows where consistent lawn formation is required. Supplied as a single piece from manufacturer Hammacher, the spreader weighs 0,025 kg and is ready for immediate bench use. Its defined 90° bend and slender 4 mm rod diameter help operators apply gentle, uniform pressure without gouging the agar, supporting reproducible colony counts and plating efficiency. Ideal as a dedicated accessory alongside Petri dishes and other plating consumables, this L-shaped bacterial cell spreader offers a durable, reusable alternative for everyday culture work in research and quality-control laboratories.

Questions about Bacterial cell spreaders, L-shaped, 90°, stainless steel, L 195 x W40 x Ø4mm
What is this article?
Bacterial cell spreaders, L-shaped, 90°, stainless steel, L 195 x W40 x Ø4mm is the article on this page. Luminix Health distributes Hammacher for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
