But do we know how heavy they are? Are there scales that could be used to weigh a single tardigrade?  <\/p>\n\n\n\n<p>&#8220;Theoretically, yes,&#8221; confirms Dr. Fabian Ehmke, Managing Director at ESSMANN | Waagen &amp; Automation. &#8220;With a high-precision, fine-resolution ultra-microbalance, the weight of a single tardigrade could be determined.&#8221;<\/p>\n\n<\/div>\n<h2 class=\"wp-block-heading\">Ultra-microbalances, the superbalances in laboratories<\/h2>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"gb-block-image gb-block-image-f8abadf4\"><img loading=\"lazy\" decoding=\"async\" width=\"599\" height=\"599\" class=\"gb-image gb-image-f8abadf4\" src=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/5995995Y-3-U.webp\" alt=\"\" title=\"5995995y 3 u\" srcset=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/5995995Y-3-U.webp 599w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/5995995Y-3-U-300x300.webp 300w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/5995995Y-3-U-150x150.webp 150w\" sizes=\"auto, (max-width: 599px) 100vw, 599px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>Ultra-microbalances are used in research laboratories, for example, and can weigh substances from 0.04 micrograms. A microgram (\u00b5g) corresponds to one millionth of a gram (0.000001 g) or one thousandth of a milligram. Examples of such substances can be tiny quantities of chemicals, biological samples or active pharmaceutical ingredients.  <\/p>\n\n\n\n<p>&#8220;To determine the weight of an active tardigrade, it must be placed in a humid environment, which must first be tared with its Petri dish. Since an ultra-microbalance, such as the UYA 6.5Y microbalance from Radwag, is capable of weighing with an accuracy of seven decimal places (0.1 \u00b5g), the weight of a tardigrade can therefore be determined theoretically.&#8221;<\/p>\n<\/div>\n<\/div>\n<div class=\"gb-container gb-container-74ef850c\">\n\n<h2 class=\"wp-block-heading\">How does an ultra-microbalance work?<\/h2>\n\n\n\n<p>This is made possible by a highly sensitive load cell, which enables samples weighing up to 6.1 g to be weighed extremely accurately.<\/p>\n\n\n\n<p>Most microbalances used in the laboratory, including ultra-microbalances, work on the principle of electromagnetic force compensation. A coil in a permanent magnetic field generates a counterforce that corresponds to the weight of the sample to be measured on the weighing pan. <\/p>\n\n\n\n<p>This technology enables the ultra-microbalance to weigh extremely small quantities with exceptional accuracy. However, it is important to note that due to their high sensitivity, these scales must be operated in a controlled, contamination-free environment to minimize interference from factors such as temperature, air pressure and humidity. <\/p>\n\n<\/div>\n<h2 class=\"wp-block-heading\">Our recommendation: The UYA 6.5Y microbalance<\/h2>\n\n<p>The UYA 6.5Y microbalance is manufactured in Europe by Radwag, one of the leading manufacturers of modern electronic scales and accessories. It is characterized by its exceptional accuracy and its ability to precisely weigh very small quantities. <\/p>\n\n<p>The UYA 6.5Y microbalance has a weighing range from 0.04 mg (minimum sample weight, U=1%, k=2) to 6.1 g and a readability of 0.1 \u00b5g, which is the smallest readability in the world.<\/p>\n\n<h2 class=\"wp-block-heading\">Special features of the UYA 6.5Y microbalance<\/h2>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>The UYA 6.5Y microbalance has various features, such as an automatically opening, wind-protected weighing chamber and a fully automatic leveling system. It can verify the user using a password, RFID card, fingerprint reader, facial recognition mechanism or any combination of these. A 10-inch display provides all relevant information in one place and informs about maintenance requirements as well as regular checks of the scale&#8217;s accuracy and sensitivity.  <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"gb-block-image gb-block-image-5e7951d0\"><img loading=\"lazy\" decoding=\"async\" width=\"307\" height=\"337\" class=\"gb-image gb-image-5e7951d0\" src=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/Gesichtserkennung.jpg\" alt=\"\" title=\"face recognition\" srcset=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/Gesichtserkennung.jpg 307w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/Gesichtserkennung-273x300.jpg 273w\" sizes=\"auto, (max-width: 307px) 100vw, 307px\" \/><\/figure>\n<\/div>\n<\/div>\n\n<h2 class=\"wp-block-heading\">Areas of application<\/h2>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"gb-block-image gb-block-image-ca3cb7e5\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" class=\"gb-image gb-image-ca3cb7e5\" src=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/scientists-working.jpg\" alt=\"Researcher in the clean room\" title=\"Researcher in the clean room\" srcset=\"https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/scientists-working.jpg 1200w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/scientists-working-300x200.jpg 300w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/scientists-working-1024x683.jpg 1024w, https:\/\/essmann.com\/wp-content\/uploads\/2023\/10\/scientists-working-768x512.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>Microbalances are often used in the pharmaceutical industry, research facilities and medical institutions as they are designed for weighing very small quantities of valuable samples.
