This Leica MZ12.5 Stereo Microscope with CLS 150 X Light Source was removed from a university lab wh (more)ere it was surplus to requirements. The unit powers up and is in good cosmetic conditionwith only minor marks. Key features of this unit are :-- High-performance stereo microscope with 12.5:1 zoom - Magnifications up to 640 x - Resolution up to 600 line-pairs / mm - ZeroStat anti static coating

The automatic feeder is dedicated for automatic dispensing of small objects onto the weighing pan of (more) RADWAG-manufactured balance to which it is connected. The feeder ensures regular feeding of the elements in accordance with determined time intervals. Operation and Compatibility The PA-04/H feeder cooperates with XA 4Y and AS 3Y analytical balances and PS 3Y precision balances. Both the feeder and the balance are automated devices. The balance carries out analysis of dosed elements and sends signal to the feeder to dispense subsequent element. The feeder features diodes, signalling its operation, and keypad allowing to control the process. Automatic feeder is equipped with function of automatic emptying of the storage bin. Vibrating Feeder Cylindrical vibrating feeder with storage bin enables safe and precise dosing of elements. The storage bin has a conical and stepped shape and is continuously welded. The stainless steel surface of adequate roughness reduces elements grating during dosing process. Variety of Applications The feeder is appropriate for dosing pills of diameter ranging from 3 to 25 mm, round and oblong, as well as details of similar shapes and dimensions Design The device is equipped with powder-coated steel housing and stainless steel cover. The storage bin features transparent lid that allows verifying quantity of remaining elements. Compatible with scales: All analytycal XA 5Y.A All analytycal XA 5Y Microbalances: - XA 21.5Y.M.A - XA 21/52.5Y.M.A - XA 52.5Y.M.A - XA 53.5Y.M.A Microbalances: - XA 21.5Y.M - XA 21/52.5Y.M - XA 52.5Y.M - XA 53.5Y.M Note! To make the feeder work, simply buy the PT0453 cable, which is not part of the set.

Accuris P7700-1000 NextPette Variable Volume Pipette, 100 to 1000ul Inaccuracy ± 1.5 to 0.6% Impreci (more)sion ± 1.0 to 0.6% Compatible Tip Size 1000ul Features - Market leading accuracy & precision - One handed volume adjustment - Convenient volume lock - Easily visible, 4 digit display - Ergonomic, thumb shaped plunger button The NextPette development project started with feedback from a wide range of researchers and technicians. The Accuris engineering team then set their sites on creating an ultra-lightweight, and ergonomic pipettor without any sacrifice in terms of durability, accuracy and precision. The NextPette incorporates many significant features and advantages truly appreciated by today's research laboratories.The easily accessible volume adjustment system reduces the time and inconvenience associated with volume selection. The uniquely positioned volume dial is located above the pipette handle, allowing for easy one handed adjustment with the user's thumb. The volume display is located on the side of the pipettor that faces the user. Unlike traditional pipettors, the NextPette does not require a second hand to rotate the pipettor 180° to observe the display.The NextPette also features an innovative, asymmetrical designed plunger button that can be rotated to match the comfort preference of the user. This button is freely adjustable to rotate continuously between wide setting, resulting in the more traditional feel of a round, larger diameter plunger button, or to a more narrow (thumb shaped) contour preferred by the majority of researchers.The NextPette's materials and components were carefully selected to minimize weight and ensure durability and a long service life. Internal components include precision plungers made of stainless steel (1ul, 10ul, 5000, and 10,000µl models) or ceramic (20ul, 200ul, and 1000ul models) and all use durable PTFE seals. The pipettors have also been designed with service in mind. They are easy to disassemble, and seals are easy to replace. Silicone lubricant is included with each pipettor. Recalibration can be done in the lab - no tools are required and the instruction manual includes full details on how to properly check pipetting accuracy and how to recalibrate if necessary. The entire pipettor is autoclavable at 121°C and resistant to UV exposure. All pipettes are factory calibrated in accordance with ISO 8655 standards and include a factory calibration certificate. INCLUDED: The Accuris P7700-1000 NextPette Variable Volume Pipette, 100 to 1000ul includes: - Calibration Certificate - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
