Roche Diagnostics Sodium Bio HT, 200 tests
Kit for determination of sodium. This product is intended for quantitative determination of sodium in aqueous solutions using the Cedex Bio HT Analyzer.
Roche Diagnostics OD Bio HT, 400 tests
The most common method to monitor the growth in bacterial and yeast cultures is the determination of the optical density of the culture suspension, which relates to the number of cells per culture volume. The manual procedure to prepare the required diutions and to perform the measurements on a photometer is usually very imprecise, error-prone and laborious. The automated testing using a Cedex Bio or Cedex Bio HT Analyzer, offers a standardized OD determination with high precison, reliability and convenience.
Chemglass Life Sciences 30mm PTFE Flake Retaining Cup
30mm PTFE Flake Retaining Cup. Cup is designed to catch all flaking that occurs with PTFE stirrer bearings. Made entirely of PTFE, the complete item consists of a compression fitting, deep perforated PTFE cup and a 50 micron porosity PTFE filter disc.
Bellco Glass, Inc. Adjustable anti-foam probe works by conductance. Rising level in bioreactor contacts the probe to trigger the controller for addition of anti-foam or addition / withdraw of media to maintain proper liquid level. Fits into 18 mm port on 3L metric head plat

AdipoGen Woollins Reagent
Chemical. CAS 122039-27-4. Formula C12H10P2Se4. MW BD9837. Woollins Reagent is an organophosphorus compound that finds widespread utilization as a reagent in organic synthesis. Woollins Reagent participates in diverse reactions, such as yielding spiro heterocycles when combined with benzoic hydrazides, generating secondary amines, forming 10-membered phosphorus-selenium heterocycles in conjunction with aromatic diols, and facilitating ring-opening deselenation and phosphorus-phosphorus coupling. Woollins? Reagent has contributed to the synthesis of biologically active compounds, including anticancer drugs, antibiotics and antiviral agents.
AdipoGen Thiamethoxam-d3
Chemical. CAS 1294048-82-0. Formula C8D3H7ClN5O3S. MW 294.73. Thiamethoxam-d3 is deuterium labelled Thiamethoxam, which is a neonicotinoid insecticide. Neonicotinoids NNIs are a family of active substances used in plant protection to control harmful insects and also in veterinary medicine. Neonicotinoids act selectively on the insect nicotinic acetylcholine receptors nAChRs, initially stimulating postsynaptic receptors, increasing Na ingress and K egress and then paralyzing nerve conduction, resulting in rapid death. This compound can be used as a reference compound, in the determination of several neonicotinoid insecticides present in bee pollen, using ultra-high performance liquid chromatography UHPLC coupled with mass spectrometry MS.
AdipoGen C14-DL-HSL
Chemical. CAS 98206-80-5. Formula C18H33NO3. MW 311.5. Synthetic. N-Tetradecanoyl-DL-homoserine lactone is a small diffusible signaling molecule and is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones AHL are involved in quorum sensing, controlling gene expression, and cellular metabolism. The diverse applications of this kind of molecule include regulation of virulence in general, infection prevention, and formation of biofilms. It appears later than shorter acyl chain AHLs in developing biofilms and, like other long chain AHLs, stimulates bacterial growth. C14-HSL also alters the proteolytic activity and enhances the migration of some strains of Proteus mirabilis. Induces violacein expression in a Chromobacterium violaceum mutant usually not able to produce homoserine lactones.
