Description
Micro reaction vessels 5,0 ml brown are laboratory glass vessels intended for micro-scale sample work, intermediate storage and reaction steps that benefit from light protection. Fabricated from brown glass, they provide a nominal volume of 5,0 ml and reduce exposure of photosensitive solutions. Each unit includes a screw cap of size N-20, a conical inner base and a ground bottom for stable placement and thorough sample recovery. External dimensions are 64 × 21 mm. Offered in packs of 12 pieces from manufacturer Witeg, these amber vessels suit analytical, preparative and quality-control routines where small liquid volumes must be sealed and handled safely. The threaded N-20 closure supports secure capping during mixing, short-term holding and transfer between workstations. With a compact 64 × 21 mm profile and conical ground base, they integrate readily into standard racks and benchtop workflows. Brown glass, defined geometry and practical pack size make them a dependable option for laboratories processing light-sensitive reagents, extracts or intermediate samples at the 5 ml scale.

Questions about Micro reaction vessels 5.0 ml brown
What is this article?
Micro reaction vessels 5.0 ml brown is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Microcentrifuge & reaction tubes, inside Microplates, PCR & reaction tubes, in Consommables.
A microcentrifuge tube, the familiar 1.5 mL or 2 mL flip-cap tube, holds a small reaction or a spin-down. The cap style, the centrifugal-force rating and whether the tube is low-binding are the specification. A PCR tube is thinner and is a different article.
A microplate is an array of wells so the same step can be done many times. A deep-well plate holds more volume. A PCR plate or a strip of tubes is thin-walled so the temperature of a cycler reaches the liquid quickly. A seal keeps the well from evaporating. The well number, the working volume and whether the plate is skirted for a robot are the choices. Diagnostic test systems are listed under ISO in vitro diagnostic systems. Methods are on PubMed.
