Condition: as good as new (ex-display), Year of construction: 2019, operating hours: 50 h, functionality: fully functional, machine/vehicle number: 19101105, roller width: 1,100 mm, Equipment: full service history, type plate available, The SDFM-1100 roll-to-roll laminator is a multifunctional laminating machine. It is designed for cold and hot laminating. The paper is laminated on one side with the foil. Then the web is re-rolled onto the roll. For cold laminating, the foil is coated with a water-based glue and dried using a heating roller with a warm air drying system. The winding system sends the paper to the laminating section, where the paper is covered with the foil by heating and roller pressure. The rollers use a heated water circulation system with constant temperature control. The paper roll is held by pins, which are controlled by a pneumatic brake. The paper is unrolled to the leveler, which is equipped with automatic leveling of the paper web before laminating, which ensures even coverage of the web with foil. In the laminator, the non-adhesive film is coated with a water-based adhesive and then dried with a heating cylinder or the film already coated with adhesive is unrolled into the laminating cylinder. The laminating cylinder is heated using induction heaters. Under the laminating cylinder, the paper is joined to the film using temperature and pressure generated by the lower rubber roller, which presses the film with the paper against the laminating cylinder. The laminated web is wound onto a core on a shaft in the receiving section, after which it can be transported to subsequent production processes.

Condition: excellent (used), Now in stock at Glendale we have this GMP QTopic 380 Laminator with Foiling/Sleeking rewinder. Having been within a small digital implant, this laminator has had little use. The laminator is in perfect working order and includes the air compressor and foiling unit. Raising ordinary print work to 'extra-ordinary'.GMP QTopic 380 has been developed to meet specific print finishing requirements and built to exacting technical standards – with fully controllable pressure and heat processes, devised to deliver optimum results with today's digital print output. The GMP QTopic 380 offers pneumatic pressure which is required to get a great finishing when laminating and/or foiling is required. The pneumatic pressure is supplied by the integrated silent air compressor housed in the Qtopic 380 stand. This semi-automatic system is hand feed with automatic sheet separation. Capable of working at speeds up to 10 metres per minute the QTopic 380 can laminator over 1300 SRA3 per hour. Turnaround times and waste are further minimised with the unique 'burst separation' system. The laminating film is micro-perforated on the edge by the robust marking device and then separated by the pneumatic burst roller. This easily separates the laminated sheets prior to the actual edge of the media, leaving clean and square datum edges from which to measure, cut, fold or guillotine. Faultless lamination. Class-leading lamination for the commercial and digital printer. Using state-of-the-art technology, combined with integrated pneumatic pressure, the QTopic 380 delivers superior bonding and faster production times – compared to standard systems. In addition, the fully adjustable heat and pressure combinations enable a wider range of laminates to be used with litho or digital printed media. Stunning foiling. For today's printers who demand stunning results with that extra ‘wow’ factor – the GMP QTopic 380 delivers more than just class-leading lamination. Metallic, coloured, patterned or holographic style foils can be added to digitally printed materials in either spot or flood treatments. This decorative effect traditionally would involve costly custom die production to create these effects. However, the QTopic can deliver instant and affordable results - and with upgraded pneumatic pressure, an even wider choice of media is now suitable for great results!

Condition: used, This listing is for 1 of 3 Hamilton Microlab 600 series dual syringe dispenser The units are in full working condition and ready for immediate use General Description The Hamilton Microlab 600 Series Dual Syringe Dispenser is a semi-automated liquid handling system designed for laboratories requiring high-precision, high-accuracy fluid transfers. Built on Hamilton’s world-renowned syringe technology, it leverages positive-displacement mechanics to ensure consistent performance across a broad range of fluid viscosities and characteristics. Semi-Automated Liquid Handling With a simple touch of the hand probe button or an optional foot switch, users can actuate the dual precision syringe drives to aspirate or dispense exact fluid volumes. This ergonomic control reduces hand fatigue and enhances repeatability in routine workflows. Precision by Design Microlab 600 diluters and dispensers achieve precise and reproducible results through positive-displacement syringe drives that are independent of fluid viscosity, vapor pressure, or temperature. This makes the instrument highly suitable for complex or sensitive fluid-handling tasks such as: Serial dilutions Titrations Standard preparations Nwsdsxhfztspfx Af Roi Reagent distribution Sample aliquoting
