How Does It Compare with Other JLab Sealers?
| Model | Operation | Controls | Sealing length |
|---|---|---|---|
| Laboratory Heat Sealer (EL-LS-5109) | Fully pneumatic, heated sealing bar or die | Microprocessor with digital display, PID temperature control, force 15–180 kg, dwell 0.0–9.9 s | 150, 300 or 500 mm |
| Sealer Machine | Hand sealing machine with a sealing transformer | Changeable time control system; dual timer for cooling | Up to 310 mm |
Choose the Laboratory Heat Sealer when seals must be made under set, repeatable force, temperature and dwell conditions, for example when comparing films and laminates. The Sealer Machine is the simpler hand-operated choice with a timer control.
What Is the Laboratory Heat Sealer Used For?
Heat sealing joins one thermoplastic material to another, or to a second material that carries a thermoplastic layer, by pressing them together under heat so the plastic softens and welds along the contact path. In this sealer a constantly heated bar or die does the heating, and because force, jaw temperature and dwell time are each adjustable on a microprocessor-based machine with a digital display, seals can be made under known conditions and repeated. Its applications are heat seal connectors, films, thermally activated adhesives, foil sealing and plastic ports.
Typical settings are packaging development and quality-control labs that work with films and laminates, polymer and materials-science labs in universities and engineering colleges, and R&D units that prepare sealed samples for later testing. The three jaw patterns give different seal faces, and running the upper and lower jaws at different temperatures can help when the two layers being joined respond differently to heat.
What to Specify When Ordering
- Sealing length — 150 mm, 300 mm or 500 mm.
- Jaw pattern — plain, straight line or diamond knurling.
- The films, foils or parts you plan to seal, and the number of machines.
- Your compressed-air arrangement, since this is a fully pneumatic model.
Frequently Asked Questions
What materials can the Laboratory Heat Sealer seal?
Thermoplastic materials and packaging materials. It joins one thermoplastic to another, or two different materials where one has a thermoplastic layer, and is used for heat seal connectors, films, thermally activated adhesives, foil sealing and plastic ports.
What sealing force does it apply?
The force exerted on the film sample can be adjusted from 15 to 180 kg to suit the job.
Can the upper and lower jaws be set to different temperatures?
Yes. The upper and lower jaws can be adjusted to different temperatures, controlled by an imported PID temperature controller.
How long can the jaws stay closed?
Dwell time is adjustable from 0.0 to 9.9 seconds.
Which jaw patterns and sealing lengths are offered?
Three jaw patterns — plain, straight line and diamond knurling — and optional sealing lengths of 150 mm, 300 mm or 500 mm.
How does it differ from the JLab Sealer Machine?
The Sealer Machine is a hand sealing machine with a sealing transformer, a changeable time control and a sealing length of up to 310 mm. This model is fully pneumatic and microprocessor controlled, with adjustable force, dwell time and separate jaw temperatures.
What information is needed for an export quotation?
Send the number of machines, the sealing length and jaw pattern, the destination country and port or city, your delivery terms (for example FOB or CIF), any packing requirements and a tender reference if applicable.
Who manufactures the Laboratory Heat Sealer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The heat sealer is built at JLab’s own works rather than bought in from a trader, so laboratories, institutions, dealers and importers deal directly with the maker, each machine is visually inspected before dispatch, and follow-up orders and parts are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Lesotho in Southern Africa, Afghanistan in South Asia, Turkmenistan in Central Asia, Estonia in Northern Europe and Peru in South America. Institutional buyers can find tender information on the JLab lab tenders page.
Other Sealing Equipment
- Sealer Machine — a hand sealing machine with a sealing transformer, a dual set timer for cooling and a spare heater bar assembly.
- Bottle Cap Sealing Machine Hand Operated — a portable, hand-operated cap sealer with two extra cap holders of different sizes.
- Ampoule Filling & Sealing Device — an electrically operated syringe-piston filler with adjustable fill volume and a burner for sealing.
