Jan 01, 2012 · Two reagent bottles were filled with nitrate stock solution with the addition of glucose and Na 3 PO 4 .12 H 2 O so that the ratio C: N: P was again 80:7:1. Experiments carried out at room temperature (one with and one without access of air), the determination of nitrate was carried out on the 8th and 15th day. 2.6.

Triple thread permits user friendly opening and closing with only a three-quarter turn Cap offer a linerless, integral lip seal DWK Reagent Bottle Wide Neck Soda ...

Common cap sizes include 33-430 (33mm), 38-430 (38mm), and GL 45 (45mm). Caps range in size from narrow mouthed to wide mouthed and often a glass or plastic funnel is needed to properly fill a reagent bottle from a larger or equal sized container's mouth. Reagent bottle caps are commonly said to be "autoclavable".

• Outer Cartons – easy to open and close. • Environment – environmentally friendly packaging for 4×2.5L Glass Bottles • Dry Reagent Bottles – Square, tamper-evident, plastic with wide neck access. • Stronger Plastic Bottles – 2.5L Plastic Bottles with a more robust design. • 500ml bottles to 20L drums (metal and plastic)

7.4 Florisil—PR grade (60/100 mesh). To prepare for use, place 100 g of Florisil into a 500-mL beaker and heat for approximately 16 h at 40°C. After heating transfer to a 500-mL reagent bottle. Tightly seal and cool to room temperature. When cool, add 3 ml of reagent water.

TeleScoop is a versatile sampling system with exchangeable tools for a wide range of applications. The tools (angular beaker, pendulum beaker, bottle holder, stainless steel beaker and catch net e.g. for taking solid and organic samples from water courses) are attached to the rod by a practical snap-in joint.

If the reagent bottle happens to be wet with deionised water, then it must first be rinsed with a little of the standard solution before the bulk of the solution is transferred to it. Were it not rinsed, then the solution would be diluted by the water, making its true concentration slightly less than its calculated value.

To maintain the highest standards with regard to purity and sterility, Bürkle has developed a single-use sampler product line. In particular, the disposable samplers from the LaboPlast™ and SteriPlast™ brands are manufactured and individually packed in a class 7 clean room (10,000).

The DURAN ® evolutionary process is, like all others, characterised by diversification and branching. At its core is the Original GL 45 laboratory bottle, made of borosilicate 3.3 glass, with easy to read scales and large labelling field for easy marking, in fired-on, highly durable white ceramic.

The samples were collected in sterilized plastic bottles of 1000 ml capacity for physico-chemical analysis while 100 ml sampling bottles were used for bacterial analysis. Water samples collected were properly labeled, stored in cooler containing an icebox to maintain stable temperature of 4 °C and immediately transported to the laboratory for
