Convenient Snip & Pour Teflon Tubes
Just snip the top of the Teflon tube and pour the contents into the sample container or extraction apparatus. The precise volume of HEM is delivered to the LCS or Matrix Spike sample. HEM contents do not adhere to the sides of the single-use Teflon tube. Inexpensive Snip & Pour tubes eliminate pipets and require no warming prior to use. Twenty 10mL tubes per pack. Each G3025 tube contains 40mg of extractable HEM per 10mL aliquot while each G3026 tube contains 10mg extractable HEM.
Oil and grease standards are also available in 30mL screw-cap bottles.
Question/Answer
Hi Environmental Express, I purchase your 10 mg HEM standards. The certificate that comes with the standards has the concentration but not the uncertainty associated with the 10 mg. Please send to me.
The uncertainty of our cat# G3026 standard is 10mg +/- 2% HEM.
