The 1000 series is a mid volume Gastight® syringe. Gastight® syringes are ideal for dispensing both liquids and gases. They have a precision machined PTFE plunger tip which creates a leak-free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.

These ODS columns are suitable for non-polar and moderately polar analytes including acids, neutrals and lipophilic compounds. All column phases are endcapped.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.

Supplier: Restek

Ultra amino columns are made of high-purity, spherical shaped type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications. Aminopropylsilane provides reproducible retention and efficiency for normal-phase or HILIC analysis of simple sugars.

Supplier: Agilent

The Hypersil BDS is both base deactivated and encapped to improve peak shapes of basic solutes by minimising interaction with unreacted silanols. Hypersil ODS adds a monolayer of octadecyl silane (C18) to the hypersil silica support.

Supplier: Avantor

Avantor® Partisil® was one of the first commercially available irregular silicas with a large surface area giving it a high loading capacity.

Supplier: Avantor

Very popular PEG high polarity MS phase for a wide range of applications, including (for example): essential oils, flavours and fragrances also alkanols. HI-WAX MS is an MS grade low bleeding cross-bonded column.

Supplier: HAMILTON BONADUZ

The 700 series syringe is the original hand-fitted Hamilton syringe. This series of syringes is ideal for dispensing volumes from 0,5 to 500 µl. The stainless steel plunger is manufactured to fit the glass barrel with a tolerance smaller than 100 millionths of an inch, resulting in unsurpassed syringe life. Each syringe is manufactured to achieve the highest level of accuracy and precision possible.

Supplier: MICROSOLV

RSA™ (Reduced Surface Activity) high quality and extremely consistent autosampler vials and caps due to reduced surface activity glass manufacturing and control processes. Excellent for low abundance or low dosage form analytes or samples that are pH sensitive, or basic in nature.

Supplier: MICROSOLV

These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level. This is an excellent choice for small, polar compounds by LCMS or HPLC.

Supplier: Biotium

Phalloidin is a toxin isolated from the deadly Amanita phalloides mushroom. It is a bicyclic peptide that binds specifically to F-actin. Fluorescent conjugates of phalloidin are convenient tools to investigate the distribution of F-actin in fixed and permeabilised cells or tissue sections. One unit (U) of phallodin is sufficient to stain one sample (200 µl staining volume). A highly selective actin filament stain for fixed and permeabilised cells. Labeled phalloidins have similar affinity for both large and small filaments.

Supplier: Thermo Fisher Scientific

Superior comfort, performance, reliability and easiness of maintenance in one of the lightest pipettes available in the market.

Supplier: Restek

These biphenyl coulmns have a greater degree of dispersion than conventional phenyls and a greater degree of polarisability than phenyl hexyls, creating higher selectivity and a greater range of usability. With heightened interactions shows substantial increases in retention for dipolar, unsaturated, or conjugated solutes and enhanced orthogonal selectivity when using methanol mobile phases.

Supplier: ProSci Inc.

Maturation of cytoplasmic tRNAs includes splicing of introns, which are located 1 nucleotide 3-prime from the anticodon in all intron-containing tRNA genes. In tRNA-leu(CAA), the first position of the anticodon, C34, is converted to 5-methylcytosine, a modification necessary to stabilize the anticodon-codon pairing and correctly translate the mRNA. NSUN2 encodes a methyltransferase that catalyzes the intron-dependent formation of 5-methylcytosine at C34 of tRNA-leu(CAA) (Brzezicha et al., 2006 [PubMed 17071714]).
