Polyethylene capsules

TEM measurements The samples after LTOC measurement were ground in an agate mortar, transferred into a polyethylene capsule and mixed with Epon812 embedding medium. Volatile substances were removed under vacuum (1.33 pa, room temperature... 

Pneumatic tube systems are also useful for rapid transference of samples irradiated In a reactor (17 ). In one such facility the sample to be Irradiated Is placed In lusteroid or polyethylene capsules and Is Inserted In a polyethylene rabbit which runs through the pneumatic tube to the side of the reactor. After Irradiation, the rabbit is returned to a hood in which chemical operations can be performed, is quickly opened and the sample removed. The pneumatic tube system la operated by vacuum rather than by compressed air to minimize... 

The irradiation time usually varies between a few hours and several days. During the irradiation, the samples, as well as standards and reference samples, are enclosed in sealed quartz ampoules, or, especially at shorter irradiation times and dry samples, polyethylene containers or foils. However, irradiation in heat-sealed polyethylene capsules has been reported to cause considerable loss of mercury, especially from standards (Brune... 

Soft gelatin capsules are not an inexpensive dosage form, particularly when compared to direct compression tablets [3]. There is a more intimate contact between the shell and its liquid contents than exists with dry-filled hard gelatin capsules, which increases the possibility of interactions. For instance, chloral hydrate formulated with an oily vehicle exerts a proteolytic effect on the gelatin shell however, the effect is greatly reduced when the oily vehicle is replaced with polyethylene glycol [3]. 

Transfer to polyethylene or gelatin-embedding capsules containing complete resin. Polymerize overnight at 45°C and then for 24 h at 60°C. 

Transfer tissne to polyethylene-embedding capsnles or gelatin capsules, fill the capsules with complete resin, and cap. Oxygen will inhibit polymerization. 

Transfer tissue to polyethylene-embedding capsules or gelatin capsules, fill the capsules with 100% LR Gold + initiator, and cap. Oxygen will inhibit polymerization. Polymerize the plastic with UV light (366 nm, two 15-W Sylvania F15T8/BLB bulbs) placed 10 cm from the capsules. Expose the capsules to the UV light for 24 h at -20°C. 

Transfer tissue to polyethylene embedding capsules or gelatin capsules, fill the capsules 100% LR Gold + initiator and cap (see Note 20). 

S)(l S,2 R) configuration. It has a molecular formula of C 25 H 35 N 3 6 S. The capsules are available for oral administration in strengths of 50 and 150 mg. Each 50-mg capsule contains the inactive ingredients D-alpha toco-pheryl polyethylene glycol 1000 succinate (TPGS), poly-... 

Each liquid-filled capsule contains 30 mg nimodipine in a vehicle of glycerin, peppermint oil, purified water, and polyethylene glycol 400. The soft gelatin capsule shell...
