Key Details

What Is a Three-Way Syringe Tap Used For?

In chemistry and physics practicals, a three-way tap lets one syringe be connected to two different destinations without pulling fittings apart. Typical uses include drawing a gas sample from a reaction flask into a syringe and then turning the lever to push it into a second syringe or tube, measuring the volume of gas given off in a reaction, and moving small volumes of liquid between two syringes in a closed system.

Push the Luer fittings together with a slight twist so they seal, and check which two ports are open before moving any liquid or gas. Turn the lever slowly during an experiment to avoid sudden pressure changes. Rinse the tap with water after use and let it dry before storage.

Polypropylene Tiles (Product Code: SLE/P/18) are white spotting tiles used to carry out drop-scale colour tests and small reactions side by side in school and college chemistry and biology laboratories. Each tile measures 118 × 93 × 11 mm and has 12 cavities of 22 mm diameter, so a dozen samples or reagent combinations can be compared at once. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM lab equipment manufacturer, at its own factory in Ambala, India.

Specifications

What Are Polypropylene Spotting Tiles Used For?

A white spotting tile makes small colour changes easy to see. Students place a few drops of a test solution in each cavity and add an indicator or reagent, for example to test for starch with iodine, to compare the pH of household liquids with universal indicator, or to preview the end-point colour of a titration before the full run. Twelve cavities let a whole series of samples or concentrations be laid out in order, so results can be read and recorded at a glance.

Polypropylene tiles are lighter than ceramic spotting tiles and less likely to chip when handled by students. Rinse the cavities with water straight after use so coloured residues do not stain, and dry the tile before storing it. They make a compact addition to any chemistry teaching kit for schools in India.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures these polypropylene tiles as the OEM (original equipment manufacturer) at its own licensed factory at Saha, Ambala, Haryana, India. Because the tiles come straight from the maker, schools, colleges, dealers and importers can order classroom quantities and repeat batches without a middleman.

At 38 mm they suit small-volume filtrations with folded filter paper, and the plastic is listed as unbreakable, which makes them a safer choice than glass on student benches. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Polythene Filter Funnels Used For?

In soil practicals, students shake a soil sample with distilled water and pour the mixture through filter paper in the funnel to obtain a clear extract for pH or nutrient tests. The same funnel separates precipitates from solutions in chemistry, for example when collecting an insoluble salt, and clarifies small water samples before testing. Its compact size suits the short filtrations common in school practicals, and it is equally useful as lab equipment for colleges in India running soil and water analysis.

Fold a filter paper circle into a cone, seat it in the funnel and wet it with a little distilled water so it clings to the wall before pouring. Support the funnel in a stand or on a small flask, pour down a stirring rod, and never fill the paper to the rim. Wash the funnel after soil work so fine particles do not carry over into the next filtration.
