The power supply converts AC line voltage into 20kHz electrical energy. This high-frequency electric (more)al energy is fed to an inverter where it is converted into mechanical vibrations. The heart of the transducer is a lead zirconate titanate electrostrictive element that, when subjected to an alternating current, expands and contracts. The transducer vibrates in a longitudinal direction and transmits the motion to the horn tip which is immersed in the solution, causing cavitation. The implosion of microscopic bubbles or voids in the solution results, intensively stirring the molecules in the medium. The Sonifier functions in two modes: Pulsed and Continuous. In Pulsed Mode, ultrasonic vibrations are transferred to a solution at a rate of one pulse per second. This pulse duration can be adjusted from 0.1 to 0.9 per second, allowing the solution to be processed at full ultrasonic intensity while the temperature builds up – particularly valuable when processing warm volatile solutions and temperature-sensitive material. In continuous mode the Sonifier can be set for continuous duty. Used for: sample preparation, cell disruption, nanoparticle dispersion, mixing, homogenization, DNA, cell lysis, protein extraction

MARSHALL Select MS-OT40LE Overhead Stirrer, 40L Maximum Stirring Quantity 40L Speed Range 50 to 2,2 (more)00 RPM Maximum Viscosity 50,000 mPas Features - High torque of 60 Ncm suitable for viscous medium stirring - Brushless DC motor ensures long life, maintenance-free operation, and safety in explosive environments - LED display for precise monitoring of actual speed - Over torque protection and safety circuits provide safe stop functions in anti-stall or overload conditions - Large chuck diameter supports many shaft types, increasing versatility - Through-shaft design allows for easy adjustment of the impeller position - Automatic resumption of stirring at preset speed after power loss - IP21 protection class offers basic protection against solid objects and dripping water - Analog speed controls displayed on the LED for easy adjustments and monitoring - Designed to accept pass-through stirrer rods for flexible setup options - Visual alarm alerts for immediate notification of system issues or malfunctions - Explosion-proof motor enhances safety in volatile environments The MARSHALL Select MS-OT40LE Overhead Stirrer stands out for its high reliability and superior performance, engineered to manage stirring tasks up to 40L. It features a versatile speed range from 50 to 2,200 RPM, suited for a wide variety of laboratory needs. This stirrer is equipped with a brushless DC motor, renowned for its long life, maintenance-free operation, and explosion-proof qualities. The MS-OT40LE includes an LED screen that displays the actual speed, ensuring precise control over your mixing processes. It's capable of handling high viscosities up to 50,000 mPas with a maximum torque of 60 Ncm, making it ideal for stirring viscous mediums. The large chuck diameter supports many shaft types, enhancing its adaptability. Safety is a paramount feature of this device, with integrated circuits that provide a safe stop function in conditions of anti-stall or overload, where over torque protection automatically stops the motor. Additionally, the through-shaft design allows for easy adjustment of the impeller position to suit varying laboratory needs. In the event of a power outage, the stirrer automatically resumes operation at the preset speed once power is restored, ensuring continuity and efficiency. The IP21 protection class provides basic protection against solid objects and dripping water, further securing the unit in active laboratory environments. INCLUDED: The MARSHALL Select MS-OT40LE Overhead Stirrer, 40L includes: - Key of Drill Chuck - Power Cord - Operator's Manual - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Precision of WLC balances Fast, accurate and repeatable weight determination. Energy-efficient elect (more)ronics and display, combined with an internal rechargeable battery, are the perfect duo to allow you to work without access to mains power. Precision not just in the name When we designed this balance, we took care of the smallest details – both those you can’t see, hidden in the solid housing, and those you can touch. This balance is the result of a combination of our experience and true precision. The power of steel The use of stainless steel for the pan guarantees you a long life for the balance. It is not afraid of contact with moist objects or accidental splashes. It has been with us for years, and will stay for a long time to come The LCD display has accompanied us for long years. During this time it has proven its reliability. It guarantees the readability of the result from many angles and is energy efficient. Internal power The internal rechargeable battery combined with the energy-saving display and electronics allow many hours of operation without mains power. Time counts The balance is equipped with a real-time clock that provides accurate time measurement in a way that is independent of external power supply. There is potential Printer, computer, flash drive or additional display – you can easily connect them thanks to the fact that the balance is equipped with interfaces: 2 x RS232, USB type A and USB type B. You can find all accessories in our regular offer. And if you have questions about compatibility, our experts will help you. Good ALIBI The ALIBI memory used in the terminal allows for safe storage of weighing records without the possibility of unauthorized interference. A single measurement remains in the ALIBI memory up to a preset limit number of days of storage, counting from the date it was taken. Under-pan weighing Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook. THBR 2.0 System Cooperation with THBR 2.0 System for ambient conditions monitoring.

The series of MUYA electromagnetic high resolution modules is designed to be incorporated into custo (more)mer’s weighing systems. A new generation’s MUYA 5 ultra-microbalance module is designed to fulfill our customers’ high expectations regarding mass measurements carried out with the greatest precision. The system of internal adjustment improves the quality of work even more by affecting measurements results. Operation of MUYA electromagnetic high resolution module is based on an electromagnetic digital converter. Compact design and inbuilt electronics ensure great possibilities when it comes to module's adaptation capabilities. Due to high precision of a measurement it is recommended to build the module into the customer's device (e.g. anti-draft chamber), thus limiting ambient conditions influence. Power supplier for MUYA weighing module comes standard.
