HSB-1 Laboratory Heat Sealer

Laboratory heat sealer for standard determination of heat seal threshold. Produces seals 5-25mm wide and up to 350mm long.

Benefits:

Choose heat sealing bar configuration, either single (upper) or dual (upper & lower, meets ASTM F2029)
User can easily change sealing bar for various surface areas or surface finishes
Accurate and repeatable seals due to precision ground sealing faces and jaw alignment system
Versatile applications for flexible materials, blister packs and pots
Low Maintenance - 12 months between calibrations

Features:

Pressure calibration of standard surface area jaw face
Temperature digital controllers, pressure and dwell time dial controllers (upgrade to precision digital controllers as required)
Jaws constructed in aluminium and silicone with precision ground faces
Range of jaw face surfaces including Matched Crimp and Teflon Coating
