EM TRIM2 Specimen Trimming Device

Accurate, Safe, and Fast Sample Trimming Conventional trimming of embedded samples involves the use of razor blades and a great deal of skill by the ultramicrotomist. The shape of the block face and the straightness of the edges of the trimmed sample has a profound effect on the sectioning characteristics. Parallel edges top and bottom are a must. To achieve this quickly and safely is challenging and potentially hazardous with a razor blade especially on hard and brittle industrial materials. Important specimens can be destroyed by a minor inaccuracy in trimming. Perpendicular viewing Milling...

With the EM TRIM2 a perfect pyramid and cutting face of both biological and industrial samples can be produced safely, rapidly and accurately within less than 60 seconds: >> With accurate, parallel edges >> With the angle of the pyramid sides set to user-preferred angle up to 60° >> With smooth and clean surfaces >> Any part of the sample can be targeted >> With perpendicular viewing of the embedded sample to determine its position for accurate milling >> With a 1 µm step rate and an ergonomically positioned feed hand wheel >> In any desired size from approximately 0.2 mm square upwards >> With...

FUNCTION AND DESIGN, EASY TO USE The EM TRIM2 is a high speed milling system with an integrated stereo microscope and LED ring illuminator for trimming of biological and industrial samples prior to ultramicrotomy. A pivot arm and adjustment assembly holds the specimen carrier for optimum orientation. It can be used with either tungsten carbide or diamond milling tools. The area of interest can be centred and a flat block face milled onto the front face of the sample. For TEM and LM, the sample must then be trimmed to shape by adjusting the angle of the pivot arm and trimming the desired block...

Various diamond and tungsten carbide millers are available. EM TRIM2 with accurate sample removal With the ergonomically positioned feed hand wheel a step advance of 1 μm per click stop can be performed. The dynamic behaviour...

During operation the user is: >> Not in contact with dangerous components as the miller is located under a protective cover. >> Safe, as the instrument will not run unless the cover is closed. >> The spindle motor stops quickly as soon the cover is opened. >> To be easily accessible the miller ON/OFF switch is integrated into the control lever for the milling action. >> Hazardous waste, resin dust and fragments, which under razor blade trimming become airborne, are drawn into an extraction and filtration unit fitted with a Hepa-filter (optional). Waste connection to the extraction and filtration...

FOR ADVANCED TRIMMING PERFORMANCE - EM RAPID In addition to the unique features of the EM TRIM2 the EM RAPID offers further opportunities to perform high end sample trimming. EM RAPID offers: Lever sample trimmed (front face observation) >> Variable milling speed between 300-20000 rpm allows settings to be adjusted for different materials. >> Pre-selection of the miller advance in steps of 0.5, 1, 10, 100 μm with each click stop of the hand wheel encoder. >> AUTO-Feed function allows safe and fast layer removal without operating the feed hand wheel. Embedded Si sample (perpendicular view) >>...
