Syringe
Syringe (Product Code: SCL-563/031) is a plastic syringe used in the chemistry laboratory to demonstrate the effect of pressure on boiling point. It works as a simple reciprocating pump: a plunger, which in modern syringes is really a piston, fits tightly inside a cylindrical barrel, and pulling or pushing it takes in or expels liquid or gas through the discharge orifice at the open front end. Because the seal is tight, the same syringe can lower or raise the pressure on a small sample in seconds, which makes an abstract idea visible to the whole class. The syringe is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among the lab consumables it offers to schools and colleges.

Typical Use
For the boiling point demonstration, draw a little hot water – hot but no longer boiling – into the syringe, point the tip upwards and push out the trapped air. Seal the tip with a fingertip or a cap and then pull the plunger back steadily. The space above the water is now at reduced pressure, and the water starts to boil even though it is cooler than its normal boiling point. Push the plunger back in and the boiling stops. Students see directly that boiling point depends on the pressure above a liquid, the same reason water boils at a lower temperature on a high mountain and food cooks faster in a pressure cooker.
Hold the barrel with a cloth because the water is hot, keep the tip firmly sealed while pulling, and never heat the plastic syringe directly over a flame; warm the water separately instead. The sealed syringe also gives a quick feel for Boyle’s law, since trapped air pushes back harder the more it is compressed, and this makes a good introduction before students take measured readings on a Boyle law apparatus.
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab from Ambala, Haryana, and sources plastic ware and other lab consumables, this syringe included, for institutions in India and international markets. Read the ScienceLab company profile for background.

- Boyle’s Law – Simple Type — for measuring the pressure and volume relationship the sealed syringe hints at.
- Three-Way Tap for Syringe — for routing gas or liquid between the syringe and other connections.
- Thermometer — to check how hot the water is before the demonstration.
- Boiling Tubes — for heating water at normal pressure as a comparison.
- Bunsen Burner — heats the water separately from the syringe.

Frequently Asked Questions
What is the syringe made of?
Plastic.
What capacity is it?
The capacity is not stated in this listing. Tell us the volume you need through our contact page and we will confirm what we can supply.
How does it show the effect of pressure on boiling point?
Pulling the plunger while the tip is sealed lowers the pressure above hot water in the barrel, so the water boils below its normal boiling point; pushing the plunger back stops the boiling.
Can the syringe be heated directly?
No. It is plastic, so heat the water in separate glassware and then draw it into the syringe.
Does it work with gases as well as liquids?
Yes. It takes in and expels either liquid or gas through the orifice at its front end.
What should an institution include in its enquiry?
The quantity, the capacity you need, the delivery location and the billing details for your GST invoice. We supply buyers in India and international markets.
