Chromatography Sprayers, with Rubber Bellow
Product Code : EL-CC-10207
Quick answer: A chromatography sprayer is a glass reservoir fitted with a rubber squeeze-bellow that atomizes a visualizing reagent (such as an iodine or ninhydrin solution) over a developed thin-layer or paper chromatogram, so separated spots become visible for identification. This sprayer is made in heat-resistant borosilicate glass and is available in 100mL, 150mL and 250mL capacities.

Visualizing Spots After Chromatography
Once a thin-layer or paper chromatogram has developed and separated a sample into its component spots, those spots are often colourless and need a visualizing reagent to be seen. Squeezing the rubber bellow draws reagent from the glass reservoir and atomizes it in a fine mist over the plate or paper, giving even coverage without soaking the medium the way dipping would. Choosing a capacity of 100mL, 150mL or 250mL depends mainly on how many plates are sprayed between refills.
Frequently Asked Questions
What is a chromatography sprayer used for?
It is used to apply a fine, even mist of visualizing reagent over a developed thin-layer or paper chromatogram so that separated, otherwise colourless spots become visible.
Why is the reservoir made of heat-resistant borosilicate glass?
Heat-resistant borosilicate glass withstands contact with a range of chemical reagents and is stable enough for repeated laboratory use.
Which capacity should I choose?
100mL suits occasional, low-volume spraying; 150mL and 250mL suit labs that spray more plates between refills.
