Class M1 mass standards are versatile measuring tools characterized by their high precision and vers (more)atility in laboratory, industrial or commercial applications. Classified as M1 metrology class, they are valued for their versatility and accuracy in mass measurement. M1 mass standard: flat polygonal sheet Nominal value: 10 mg Material: nickel silver M1 Class Mass Standards – Key Features High-Level Precision - M1 class mass standards are designed to ensure precision in mass measurements. Permissible deviations from the actual mass are set with strict standards. Versatility of Applications - Characterized by versatility, M1-class standards are used in fields such as laboratories, industry, commerce and other areas requiring precise weight measurements. Measurement Stability - M1-class mass standards are stable over time, meaning that they maintain their measurement precision even despite prolonged use. This feature is especially important for tools that are used regularly. Operation in a Wariety of Ambient Conditions - M1 class mass standards are designed to cope with both laboratory, industrial and commercial conditions. Application 1. Analytical Laboratories In analytical laboratories where precise measurements are crucial, Class M1 mass standards are used to calibrate medium-precision balances. 2. Manufacturing Industry In the manufacturing industry, where product quality control is important, M1 class mass standards can be used to calibrate balances used in the manufacturing process. 3. Weighing Trade In the weighing trade, where measurement precision is required by law, M1 class mass standards can be used as a reference for calibrating commercial balances. 4. Testing Laboratories In research laboratories, Class M1 mass standards can be used to ensure precise weight measurements. Class M1 mass standards are versatile tools that are used in various areas of life. Their ability to adapt to different conditions makes this class of standards highly valued in the world of science, industry and commerce alike.

Millipore Milli-Q Academic Water Purification System Cat no. ZMQS50001 This item was removed fr (more)om a university lab where it was surplus to requirements. The unit powers on with the water running, but it says that cartridges need changing. It was not tested further. It is in reasonably good cosmetic condition, with some marks from use.

Boekel Scientific 115001 Block Heater w/Touch Screen, 1 Block, 115V The Programmable Heating Blocks  (more)are designed for precise controlling of sample temperatures. Heating Blocks, also known as dry bath incubators, use aluminum inserts to suit the use of many types of laboratory test tubes, plates, and containers. Boekel programmable heating blocks are designed to be used with standard aluminum dry blocks (nominally 3” deep x 3 ¾” wide x 2” high) of varying configurations for heating test tubes, microtubes, and other small vessels. The Programmable Heating Blocks use an advanced touch screen control system to create and store programs. Programs can have a maximum of five different temperature steps and there is a repeat function for thermal cycling procedures. An option external temperature probe is available for spot temperature checking and controlling the unit temperature. *Block sold separately* Features •Readily Recognizable Icons to Start, Stop and Pause Temperature Control on a Bright Color Touch Screen •Save up to 25 Programs for Rapid Sample Processing •One, Two, and Four Block Models to Fit Your Workflow •Slim Design to Conserve Bench Space •Optional External Temperature Probe •UL, CE, CSA approved Modern laboratories require modern equipment to reduce repetitious procedures and increase accuracy and throughput. The Boekel Scientific’s programmable heating blocks are designed to accommodate the most basic sample incubation procedures to multi-step heating processes and thermal cycling procedures. The slim One, Two and Four block design allows for more bench space and a configurable work flow. The optional external temperature probe is great for spot checking temperatures or controlling block temperature based on the actual sample temperature.
