Simple appliances for cooking gases lighter than air Manufacturer,Supplier and Exporter in India

Simple appliances for cooking gases lighter than air (Product Code: SCI-988/09) is a test-tube gas generator used to prepare gases lighter than air and collect them by upward delivery, a basic item of school chemistry lab equipment. An 18 mm × 160 mm glass test tube holds the reactants, and a straight 8 mm glass outlet through a holed rubber stopper points the gas upwards. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Apparatus for Gases Lighter than Air Used For?

In this catalogue name, “cooking” means preparing: the set generates a gas and lets it be collected by upward delivery, also called downward displacement of air. A dry receiving tube is held mouth-down over the straight outlet, and because the gas is less dense than air it rises into the tube and pushes the air out at the bottom. The method suits light gases such as hydrogen, and ammonia, which is lighter than air but too soluble to collect over water. It fits naturally into a chemistry teaching kit for lessons on preparing gases.

Clamp the generating tube upright so that the straight outlet points vertically, and hold the receiver steady and close over it. Hydrogen and air form an explosive mixture, so keep flames away from the generator, use small quantities and test a filled tube with a lighted splint held at arm's length. Ammonia irritates the eyes and nose, so prepare it in a fume cupboard or a well-ventilated room.

What to Specify When Ordering

• The number of sets for your class or practical groups.
• How many receiving test tubes you need, as they are not part of the listed set.
• Spare straight outlet tubes and holed rubber stoppers.
• A stand and clamp, if you do not already have one to hold the generator upright.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, makes this upward-delivery gas set as the OEM (original equipment manufacturer) at its own licensed factory at Saha, Ambala, Haryana, India. Because the apparatus comes factory-direct rather than through a trader, schools, colleges, dealers and importers deal with the maker itself on quotations, repeat orders and replacement parts.

Frequently Asked Questions

What does “cooking” mean in the product name?
In Simple appliances for cooking gases lighter than air, “cooking” means preparing or generating a gas; no cooking or kitchen use is involved. The glass set produces a gas lighter than air and delivers it upward into an inverted receiver.

What is included with the Simple appliances for cooking gases lighter than air?
The Simple appliances for cooking gases lighter than air comprise a glass test tube 18 mm in diameter and 160 mm long, a straight glass tube with an outer diameter of 8 mm, and a rubber stopper with a hole to hold the glass tube.

Which gases can be collected with this set?
The Simple appliances for cooking gases lighter than air are intended for gases less dense than air, such as hydrogen or ammonia, collected by upward delivery into an inverted tube. Gases denser than air, like carbon dioxide, need a downward-delivery arrangement instead.

How is collected hydrogen tested safely?
With the Simple appliances for cooking gases lighter than air, hydrogen is tested by holding a lighted splint at arm's length to the mouth of a small filled tube; a squeaky pop confirms it. Keep flames away from the generator itself and wear eye protection.

Who manufactures the Simple appliances for cooking gases lighter than air?
The Simple appliances for cooking gases lighter than air are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and are supplied factory-direct to institutions, dealers and importers.

Can the sets be ordered in bulk for several schools?
