Bell Jar (Plant Physiology) Manufacturer,Supplier and Exporter in India

Bell Jar (Plant Physiology) (Product Code: SCL1455/020) is a bell-shaped glass cover, 20 x 10 cm, used to enclose a small plant, specimen or piece of apparatus so that the air around it can be controlled and observed in plant physiology practicals. Made of thin, transparent, heat-resistant glass with care for optical clarity, it can also contain a vacuum when set on a suitable plate. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Plant Physiology Bell Jar Used For?

To show transpiration, a well-watered potted plant is placed under the jar with the pot and soil wrapped in polythene; within a few hours droplets form on the inside of the glass, and cobalt chloride paper placed inside turns from blue to pink. For photosynthesis, a destarched plant kept under the jar beside a dish of alkali that absorbs carbon dioxide is compared with a control plant, and the leaves are then tested with iodine. Germinating seeds under the jar with a dish of lime water show that respiration releases carbon dioxide.

Stand the jar on a smooth glass plate and seal the rim with a thin film of petroleum jelly whenever the enclosed air must be isolated. The clear glass lets students watch changes without lifting the cover, which is why the bell jar remains standard botany lab equipment in India for these three classic experiments.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this bell jar and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because it is made by the company rather than bought in from a trader, schools, colleges, dealers and importers receive it factory-direct, and repeat orders or replacements after breakage are handled by the manufacturer itself — just ask. More about the company is on its profile page.

Related Biology Lab Equipment

Materials and apparatus used with the bell jar in plant physiology work:

• Cobalt Chloride Paper — changes colour to show water vapour released under the jar.
• Lime Water — turns milky to show carbon dioxide from respiring seeds.
• Iodine Sol — for the starch test on leaves after a photosynthesis experiment.
• Vacuum Pump, Hand — for demonstrations that need the air removed from under the jar.
• Bell Jar, Knobbed — an alternative style with a knob for easier lifting.

Further plant physiology apparatus is listed in the Biology Lab category.

Frequently Asked Questions

What size is the Bell Jar (Plant Physiology)?
The Bell Jar (Plant Physiology) measures 20 x 10 cm. If the fit over a particular pot or base plate is critical, confirm the height and diameter with ScienceLab through the contact page before ordering.

Can the Bell Jar (Plant Physiology) be used for vacuum demonstrations?
Yes. The Bell Jar (Plant Physiology) can contain a vacuum, but it needs a flat base plate, a sealed rim and a suitable pump. As the glass is thin, use a gentle vacuum, keep students at a distance and wear eye protection.

Is a base plate included with the Bell Jar (Plant Physiology)?
A base plate is not listed with the Bell Jar (Plant Physiology). Please state in your enquiry whether you need one, along with any pump or indicator papers, so that ScienceLab can confirm the items in the quotation.

Can the Bell Jar (Plant Physiology) withstand heat?
The glass of the Bell Jar (Plant Physiology) is heat resistant, which helps with warm-room and sunlight experiments. It should still never be placed over a direct flame or exposed to sudden temperature changes, as the thin glass can crack.

Who manufactures the Bell Jar (Plant Physiology)?
The Bell Jar (Plant Physiology), code SCL1455/020, is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is supplied factory-direct to institutions and dealers.

How should the Bell Jar (Plant Physiology) be cleaned and stored?
Wash the Bell Jar (Plant Physiology) with warm water and mild detergent, wipe any petroleum jelly off the rim, dry it with a soft cloth and store it upright on a padded shelf where it will not be knocked.

Can schools order several Bell Jars (Plant Physiology) at once?
Yes. Several Bell Jars (Plant Physiology) can be quoted together; include the quantity and delivery location in your enquiry. ScienceLab supplies schools and colleges in India and international markets directly from its Ambala factory.
