Plunger penetration apparatus
Plunger penetration apparatus (Product Code: SLE/CE/52) is a drop-plunger instrument used to determine the consistency of masonry cement and building limes in construction-materials laboratories. A 90 g plunger assembly falls 100 mm into mortar held in an 80 mm diameter test cup, and the penetration depth shows how stiff or fluid the mix is. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of engineering lab equipment, at its own factory in Ambala, India.

What Is the Plunger Penetration Apparatus Used For?
Masonry cement and lime mortars must be brought to a standard workability before their other properties are tested, and this apparatus puts a number on that workability. Fresh mortar is filled into the test cup in layers with the tamper and levelled, the cup is placed in the recess of the steel base, and the plunger is released from 100 mm above the surface. The water content is adjusted until the penetration falls within the range your test procedure specifies.
Students quickly see how a small change in water alters penetration, which makes it useful technical educational equipment for building-materials practicals. Keep the plunger shaft clean and dry so it falls freely, release it without pushing, and wipe the cup between mixes so old mortar does not change the next reading.
What to Specify When Ordering
- Number of apparatus units required
- Additional test cups (80 mm diameter × 70 mm deep) for testing several mixes in sequence
- Whether a spare tamper should be included
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and manufactures the Plunger penetration apparatus as the OEM at its licensed factory at Saha, Ambala, Haryana. Buyers therefore order from the maker itself, and consignments are dispatched factory-direct to colleges, testing labs, dealers and importers.
Additional test cups and tampers for units already in service can be requested from the manufacturer — ask us with your order reference. The manufacturer’s background is described on the ScienceLab profile page.

Frequently Asked Questions
What does the Plunger penetration apparatus measure?
The Plunger penetration apparatus (SLE/CE/52) measures the consistency of masonry cement and building lime mortars by how far a 90 g plunger assembly penetrates the mortar after dropping from a height of 100 mm.
What is supplied with the Plunger penetration apparatus?
The Plunger penetration apparatus is supplied complete with a test cup 80 mm in diameter and 70 mm deep and a tamper. The steel base has a recess that locates the cup, and the vertical column carries the plunger assembly.
How heavy is the Plunger penetration apparatus?
The Plunger penetration apparatus weighs approximately 6 kg. Its steel base keeps it steady on the bench while the plunger drops, yet it is light enough to move between laboratory work areas or store in a cupboard.
How is the plunger penetration test different from a flow table test?
Both assess mortar consistency, but the Plunger penetration apparatus reads the depth a falling plunger sinks into the mortar, while a flow table measures how far mortar spreads after repeated drops. Your test specification decides which method applies.
Who manufactures the Plunger penetration apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Plunger penetration apparatus, producing it at its own factory at Saha, Ambala, Haryana, India, and supplying buyers in India and international markets directly.
What should I include in a quotation request for the Plunger penetration apparatus?
For a Plunger penetration apparatus quotation, include the number of units, any extra test cups or tampers, and the delivery location. Send the request through the contact page or add the product to the enquiry cart.
