The super-soft gel cushion conforms to the patient's face to ensure a gastight
fit that is more secure than the PVC cushion and has a lower profile on the face.
The latter is usually done by brief hot melting two sheets of packaging material together to form a gastight
1g/mL) were consecutively added via a gastight
syringe under argon into the reaction vial.
Yet contacts that counteract cold creep to form a reliable, gastight
connection are available.
The action of waves and currents was recreated by adding 2 1 of FSW and 4 g of slick oil, with a gastight
syringe, to a stainless steel blender pitcher (Waring CB15; Waring Commercial, Torrington, CT).
Scales on the tubes were calibrated by adding 50 [micro]m of water, from 50 to 2000 [micro]m, using a syringe (1700 Series Gastight
Syringe; Hamilton Co.
For methane determination, 500 u l gas was sampled from the headspace of incubation vessels in an gastight
(r) Syringes, Hamilton Bonaduz AG, Switzerland) into SRI310 gas chromatograph equipped with a thermal conductivity detector (TCD) and Carboxen - 1000 column (mesh side 60/80, 15 FT x 1,8 INS.
They also offer gastight
connections to meet the needs found in some hazardous and controlled production environments.
Gas samples were collected from the chamber headspace approximately 1 h after chamber closure using a 25-mL gastight
syringe and immediately transferred to pre-evacuated 12-mL glass vials (Exetainer; Labco, High Wycombe, UK).
Key statement: A tire with a built-in self-sealing layer includes an external rubber tread, a carcass reinforcer, a gastight
layer arranged towards an inside location relative to the carcass reinforcer, an anti-tack layer arranged furthest towards the inside location and a self-sealing layer adjacent to the anti-tack layer and arranged towards the inside location relative to the gastight
Apos 1 hora, amostras de 1 [micro]L de gas foram coletadas dos recipientes atraves de um septo de silicone, com auxilio de uma seringa (Hamilton, Gastight
, Nevada, EUA) e analisadas em cromatografo marca Thermo Finnigan, modelo Trace 2.
A total of 850 g material was filled into 1500-ml gastight
polyethylene jars (Duytan Corp.
