Therefore, the tubing has to be fitted with stoppers.\u00a0<strong>We use rollers of very large diameter<\/strong>\u00a0\u2013 this leads to the elimination of such strains and prevents tubing motion. A larger portion of tubing is compressed with better pressure distribution. The\u00a0<strong>elasticity of the tubing is protected<\/strong>.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Instead of rollers we use\u00a0<strong>special plastic ball bearings with glass beads<\/strong>. The gliding of such rollers requires only a minimal force and the\u00a0<strong>corrosion resistance<\/strong>\u00a0in the case of spill is excellent.<\/p>\n<p>A special off-centre lever using a spring of non-corrosive material applies the compression force on the tubing softly and gradually.<\/p>\n<p>The final pressure of the liquid is reduced by the spring to 0.1\u20130.2 MPa (according to the tubing used).\u00a0<strong>The pressure does not increase even when the line is blocked.<\/strong><\/p>\n<p>The\u00a0<strong>pump head is large<\/strong>\u00a0and has two centers of asymmetry, which reduces pulsation several times. The head is made of hard, chemically stabilized material<\/p>\n<p>The stepping motor or BLDC motor, driven by\u00a0<strong>quartz-controlled electronics<\/strong>, assures a\u00a0<strong>high precision of the flow rate<\/strong>. The ratio of speed control is 1:1000.<\/p>\n<p>The laboratory space is very expensive, therefore we have\u00a0<strong>made our peristaltic pumps as compact as possible<\/strong>\u00a0(all have just 1 l of volume). They are several times smaller than other peristaltic pumps on the market and therefore, so handy in use.<\/p>\n<p>&nbsp;<\/p>\n<h3>Benefits of great importance for your laboratory<\/h3>\n<ul>\n<li>Even without any fixation the tubing will not move at all in and out of the head.<br \/>\nSince the lateral forces on the tubing have been eliminated,\u00a0<strong>no stoppers are required<\/strong>.<\/li>\n<li><strong>Tubing life increases considerably and flow rates remain constant<\/strong>, since the tubing compression is kept in the range of elasticity of the tubing.<\/li>\n<li>The tubing economy is very important. Low cost tubing can be used with good results.<\/li>\n<\/ul>\n<p>[\/cmsmasters_text][\/cmsmasters_column][\/cmsmasters_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[cmsmasters_row data_padding_bottom=&#8221;50&#8243; data_padding_top=&#8221;20&#8243; data_bg_color=&#8221;#ffffff&#8221; data_color=&#8221;default&#8221; data_bot_style=&#8221;default&#8221; data_top_style=&#8221;default&#8221; data_width=&#8221;boxed&#8221; data_shortcode_id=&#8221;zzje5dk3dk&#8221;][cmsmasters_column data_width=&#8221;1\/3&#8243; data_shortcode_id=&#8221;ihyfec7ld&#8221; data_animation_delay=&#8221;0&#8243; data_border_style=&#8221;default&#8221; data_bg_size=&#8221;cover&#8221; data_bg_attachment=&#8221;scroll&#8221; data_bg_repeat=&#8221;no-repeat&#8221; data_bg_position=&#8221;top center&#8221;][cmsmasters_image shortcode_id=&#8221;0bfz11b97f&#8221; align=&#8221;center&#8221; animation_delay=&#8221;0&#8243;]14500|https:\/\/attekno.com\/wp-content\/uploads\/2018\/04\/Reliable_lab_peristaltic_pump__LAMBDA-277&#215;300.jpg|medium[\/cmsmasters_image][\/cmsmasters_column][cmsmasters_column data_width=&#8221;2\/3&#8243; data_shortcode_id=&#8221;1d4cth5ftf&#8221;][cmsmasters_text shortcode_id=&#8221;r69e1hbr4s&#8221; animation_delay=&#8221;0&#8243;] were developed as the result of twenty years of laboratory experience and involved the systematic elimination of the imperfections found in other peristaltic pumps on the market.
