Manometer Cylinder with Piston Temperature Meter
Product Code : SCL-CL-11877
Manometer Cylinder with Piston Temperature Meter (SKU SCL-CL-11877) is a Boyle's law apparatus: air trapped in a graduated cylinder is squeezed or expanded by a screw-type plunger while a manometer reads the pressure and a digital thermometer checks that temperature stays constant. It suits Class 9–11 physics and chemistry gas-law practicals. Science Lab Supplies sends it from Ambala, India in response to enquiries from schools, colleges, training institutes, distributors and tender contractors.
Specifications
The table gives each specification of this Boyle's law cylinder on its own line. In short, the graduated cylinder shows the air volume directly, the screw plunger changes it in controlled steps, the manometer reads pressure in pascals with 5% accuracy, and a digital thermometer monitors ambient temperature to confirm the constant-temperature condition.

Applications and Experiments for the Manometer Cylinder with Piston
The apparatus lets students verify Boyle's law themselves: halve the air volume and watch the pressure roughly double, while the thermometer confirms temperature has not drifted. It fits the gas-law topics of NCERT Class 11 chemistry (states of matter) and physics (kinetic theory), and introductory college labs.
- Class 9 science: compressing air to show that gases are compressible, then contrasting it with reduced pressure in the Microscale Vacuum Apparatus with Hand Pump.
- Class 11 chemistry and physics: plotting pressure against volume and against 1/V.
- Discussing the pressure, volume and temperature relationship for a fixed mass of gas, cross-checking room temperature with a −10 to 120 °C Thermometer (with no Mercury).
- Diploma and first-year college labs: introducing gas-law measurements and experimental error.
Turn the plunger slowly and pause before each reading, so the air returns to room temperature after compression.
Standard Scope of Supply
The apparatus is supplied as the graduated cylinder with screw-type plunger, the manometer scaled in Pa and the digital thermometer. Any optional accessories you request are listed separately on the quotation, so the scope can be checked against a tender specification before ordering.
Packing, MOQ and Lead Time
Science Lab Supplies will quote a single unit for demonstration or several for group practicals, stating packing, delivery time and price for that number. As a chemistry lab instruments supplier, it can put other gas-law and pressure apparatus on the same quotation for one delivery.
Holding an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Gas-law benches can be priced by placing this cylinder in the enquiry cart or by writing on the contact page; the lab tender page covers purchases made through tenders.
Frequently Asked Questions
Which law does this apparatus demonstrate?
Boyle's law: at constant temperature, the pressure of a fixed mass of gas is inversely proportional to its volume. Compression raises the pressure; expansion lowers it.
How accurate is the manometer?
The pressure scale is in pascals with an accuracy of 5%, adequate for verifying the inverse relationship and plotting a clear P–V graph in school and college practicals.
Who supplies the Manometer Cylinder with Piston Temperature Meter?
Science Lab Supplies dispatches this apparatus from Ambala, India, preparing quotations for the exact quantity of units needed by schools, colleges, training institutes, distributors and tender contractors.
Why is there a thermometer?
Boyle's law holds only at constant temperature. The digital thermometer lets students check that the room and the trapped air have not warmed during the readings.
